Reverse: 1999 | How to Get 100/100 on All Thief of the Thieves Missions (A-Rank Mission Guide)

Thief of the Thieves is a unique side activity which has arrived in Reverse: 1999 alongside the version 1.1 flagship event, The Theft of the Rimet Cup. This exclusive game mode reveals the backstory of Malenia, the master thief who also joined Re1999 as a 6-star Beast unit, via four curated missions which challenge your decision-making skills. As Malenia, you are tasked with guarding (or stealing) a certain prized relic on display at a gallery or museum and you must make the correct decisions to ensure that you are successful: make a mistake or choose the wrong thing and everything can come crashing down.

While the missions themselves are already quite entertaining, scoring a high rating on them is important if you want to claim all of the rewards that the game mode has to offer. Each mission has a Rating score out of 100 and, if you manage to score above 90 points, you’ll earn an A Rating and get a bunch of useful in-game materials. Scoring big is also required to get certain other rewards, such as a challenge in the Roar Jukebox which awards 1150 Decibels. Getting 100/100 can be difficult, though, so we’re here to guide you through the process for all 4 of the available event missions. 

Here’s how to score 100/100 in all four of the Thief of the Thieves event missions in Reverse: 1999.

What is Thief of the Thieves in Reverse 1999?

Before we go any further or explain how to get the best rating and score possible in Thief of the Thieves, what actually is this event? Thief of the Thieves is a little side activity that arrived in R1999 as part of The Theft of the Rimet Cup event, the flagship event of version 1.1. Alongside a unique event story involving master thief Malenia and Pickles the arcanist border collie, the event also brings several exclusive activities to take part in, namely the Bio of the Great Thief and Thief of the Thieves game modes. If you wish to learn more about the other game mode, Bio of the Great Thief, you can check out our guide on its tricky final mission here. 

Thief of the Thieves is a big departure from anything else in Reverse 1999. In each of its four missions, you’re tasked with either defending a priceless artefact from those who wish to steal it or with actually carrying out the theft yourself. This process involves making a variety of decisions which will impact your final score and rating: make the correct decisions and prioritise the right events and your score will increase, earning you more rewards in the process, but the inverse is also true, with poor decision making resulting in a lower rating. 

The event is a super fun brainteaser and works brilliantly. Unfortunately, even if you wanted to dive into Thief of the Thieves as early as possible, it’s locked off until you progress far enough in The Theft of the Rimet Cup event storyline. To be more specific, you need to complete the sixth event mission – ‘Confluence of the Routes’ – to unlock Thief of the Thieves. Once you’ve done that, though, you’re free to ignore the story and complete all four of the side activities at your leisure. 

Thief of the Thieves Event

Thief of the Thieves Availability

Lastly, as a limited event, Thief of the Thieves isn’t sticking around forever. The Theft of the Rimet Cup is split into two phases, with the first phase lasting from November 9th to November 23rd and the second phase lasting from November 24th to December 7th. Once the second phase of the event begins, two new game modes – The Puppy & The Hippie and Pickle’s Free Translation – will go live and take the place of the previous two modes. 

Alongside Bio of the Great Thief, Thief of the Thieves will become unavailable once the phase 2 game modes launch on November 24th. With that in mind, you have from November 9th to November 23rd to complete all of the Thief of the Thieves activities and claim all of their associated rewards in Reverse 1999. If you leave it too late, all of the rewards, including the Clear Drop, will disappear and become unavailable so make sure to get this event done as quickly as possible.

How to Get 100 Points in All Thief of the Thieves Missions in Reverse 1999

Mission 1: Disc of Turin

The first mission you have access to is the Disc of Turin. This is the first artefact Malenia had to look over once she became the new head of the Ramirez security company and it’s the most important part of the Italian History section in the museum. 

Each mission is split up into 5 stages, each of which has 2 AP. Resolving an Emergency or Daily Affair requires you to spend 1 AP, limiting the number of actions you can do on a single day: for example, if there are two Daily Affairs active at once but you only have 1 AP left, you need to determine which is more of a priority. If you choose incorrectly, it could even result in a loss of points once the day has concluded, so figuring out which Affairs are the highest priority is of the utmost importance. 

Mission 1, Disc of Turin

Day 1: 

• The first Daily Affair involves an old guard who has worked for Malenia’s father for many years and is claiming that the CCTV doesn’t work. In response, choose “Check it yourself” for a +5 Rating.
• As for the second Daily Affair, choose “Drive him away” in response to the man claiming to be a friend of Malenia’s father. This will also net you a +5 Rating.

Day 2: 

• For today’s Emergency, you’ll need to “Mediate the issue” with the upset plumber to earn +10 to your Rating.
• For the Daily Affair, see if you have the one at the top of the gallery with the famous collector. If you do, choose to “Refuse his request.”
• If the previous Daily Affair isn’t available, select the exclamation mark closest to the paintings near the bottom of the gallery and choose “Clean the flowerbed” of the dog’s gift. Cleaning it will result in a +5 Rating, whereas leaving it alone will result in a -5 Rating.

Mission 1, Day 2 Emergency

Day 3: 

• The next Emergency asks you to choose between upgrading the gallery with more guards or more arcane props. Of these choices, pick “More arcane props” for a +10 Ratings boost.
• Of the two remaining Daily Affairs, ignore the one regarding spirits and focus on the one regarding the rats. Pick to “Drive them away” for an easy +5 Rating. 
• Ignoring the Spirits will also add +5 to your Rating during the Expired Issue section once the day ends. 

Day 4: 

• The Emergency for day 4 involves forcibly calming down two drunkards, which results in a short combat encounter. Beat back the drunks and you’ll net yourself +5 Ratings.
• As for the remaining Daily Affair involving a shady man wandering the gallery’s halls, you’ll want to “Test him” for a hint for the Mainedonty mission and +5 to your Rating. 

Once you reach Day 5, you’ll only have one available Emergency to deal with where you must beat back the thieves who have tried to infiltrate the facility over the last few days. Like on day 4, this results in a small fight which shouldn’t be too hard. This final activity will add another +10 to your Rating, leaving the final Rating total for the Disc of Turin at 100/100.

Mission 2: Mainedonty

After successfully guarding the Disc of Turin, your next goal in the Thief of the Thieves event in Reverse 1999 is to defend the Mainedonty. This artefact is a strange type of coin which, seemingly has both a mind and will of its own (as well as a few sharp teeth, to boot).  

Just like in the first mission, you’ll have to defend the object and deal with Emergencies and Daily Affairs across 5 days. This mission is where you’ll start seeing a lot more variance and change run-to-run. In certain days or stages, some Daily Affairs only have a chance of spawning. This means that you could get one that I or some other player didn’t get. We’ve tried to catalogue all of the variance we’ve noticed, but just be aware of it going forward. 

Mission 2, Mainedonty

Day 1:

• The first Emergency for the Mainedonty exhibit tasks you with dealing with some outlaws who have broken into the gallery. “Stop them!” by defeating them in a battle, earning you +5 Ratings.
• Of the two remaining Daily Affairs, choose the one regarding the guard who was bitten by the Mainedonty coin. From here, choose to “Compensate the guard” for his injury which will add +10 to your Rating.
• The other Daily Affair had to do with the guard and the CCTV from Mission 1. By leaving him alone, he’ll soon figure out the CCTV by himself, netting you another +5 points. 

Day 2:

• For day 2’s Emergency, “Call an ambulance” for the unwell gentleman. This won’t get you any extra points, but it will remove the Plans Effect from the final fight. 
• There will only be one Daily Affair remaining after this. The shady man from Mission 1 warned you not to trust the woman taking pictures so, following his words, “Refuse her request” to get +5 Ratings.

Taking Out the Outlaws

Day 3:

• This day’s Emergency is another one asking for a choice between mundane security methods or more Arcane props. Like before, pick “More arcane props!” to remove the Specialization Effect. from the final battle. 
• After this, there are a few different options. Four potential Daily Affairs can potentially appear here and, with only 1 AP remaining, you can only select one. The highest priority Affair has to do with a rich man wanting to see something behind the glass. “Refuse his request” to earn some Rating points but, most importantly, avoid a Rating deduction in the Expired Issues section at the day’s end. 
• If you don’t have that Affair, the next highest priority activity has to do with the dogs again. Like before, choose to “Clean the flowerbed” to avoid a Rating reduction and earn +5 points.
• If you don’t have either of those, you’ll either have to “Use more guards to maintain order” or “Drive him away” to secure your Rating bonuses. 

Day 4:

• Day 4’s Emergency only has one option – “Darn it!” – but will still get you +10 Ratings. 
• Of the two remaining Daily Affairs, help the guards who have raised objections about the night shift schedule. Instead of agreeing with them, “Insist on the schedule” to get 10 more Rating points.

Like before, Day 5’s Emergency is a set battle where you need to “Protect the exhibit” from an invisible man who has snuck in to steal the Mainedonty. Get it over and done with and another 10 Ratings will come flying your way. If you follow everything correctly, you’ll end the Mainedonty mission with an A Rating and 100/100 score.

Mission 3: Crystal Skull

The third mission in Thief of the Thieves is the Crystal Skull. After failing in her duties to defend the artefact stolen by Sean the Great, Malenia has decided to play the role of the thief so she can better learn the ins and outs of security work. As such, the objectives of the Crystal Skull (and its subsequent mission, The Football Match) are quite different to the first two tasks.

Additionally, each mission is now split up into 6 Stages as opposed to 5 Days. With an extra stage added to the mission, you’ll have more opportunities to either gain or lose points. 

Mission 3, Crystal Skull

Stage 1:

• The first Emergency asks you to begin thinking like a thief. Instead of searching for blind spots, “Talk to the guards” to learn the shift schedule and get +10 Rating points. 
• For today’s Daily Affair, answer “Enable the smoke alarm” in response to Acey’s question for a +5 Rating. 

Stage 2: 

• For stage 2’s Emergency, choose to focus your plan on “The guards” and ignore the ventilation ducts. Acy will praise you on a wise choice, earning you +a 10 Rating. 
• Out of the two remaining Daily Affairs, pick the exclamation mark at the top of the gallery. You’ll be asked how, hypothetically, you will escape if you are caught when checking the ventilation duct and you should respond with “Use the Sweet Dream Hallucinogen.” You’ll get a +5 Rating gain and avoid a -5 Rating loss in the Expired Issue section. 

A Wise Choice, Malenia

Stage 3:

• Select “Perhaps a bit of Sleepy Popping Beans” for the stage 3 Emergency. This will net you 10 more points for your Rating. 
• As for the second Emergency of the day, simply choose to “Enter the hall.” The Sleepy Beans from before will have the guards sleeping like logs, removing the Well-Trained Effect from the final fight. 

Stage 4:

• To get positive points (+5 Rating) on stage 4’s Emergency, you need to select “Check the nearby exhibits” instead of choosing to search the guards. 
• After that, one of two Daily Affairs will spawn. For the Daily Affair regarding an emergency exit, choose “Jump out of the window.”
• Meanwhile, if you have the Daily Affair regarding the curious cat, “Use the Bubble Distractor” to keep it nice and occupied. 

Stage 5:

• For the day 5 Emergency, “Use the Sticky Balls” on the big bloke guarding the Crystal Skull. This will remove the Coffee Lover Effect. 
• The remaining Daily Affair, stop the Crystal Skull’s singing by choosing to “Wrap it in clothes.”

This will take you to the stage 6 final fight against the big bloke and his goons. Wipe them out, escape the exhibition with the Crystal Skull and this mission will be complete. If you did every step correctly, you should also be walking away with 100/100 and an A Ranking.

Mission 4: The Football Match

Finally, the last Thief of the Thieves mission you’ll get access to is The Football Match. This is easily the most difficult mission in the event with a lot of variances and chances to mess up and lose points. If you want to be the one to steal this famous oil painting, you’ll need to be on the top of your game. 

Compared to the previous three missions, it’s important to note that The Football Match has 3 AP available at each Stage instead of having just 2 AP. This gives you an additional Emergency or Daily Affair to deal with each Stage which, of course, comes with either the risk or reward of losing or gaining Rating points. However, just follow our guide as best as you can and you should come away with an easy A-Ranking and 100/100 score.

Mission 4, The Football Match

Stage 1:

• The most important event in the first stage of the Football Match is the Emergency. Instead of talking to the guards, “Look up the Guidance on Security” to find some flaws in Iverson’s defences, earning you a +5 Rating. 
• Next, you’ll have to contend with a second Emergency where you need to exploit the flaws in Iverson’s security. At this point, select “Check the CCTV.” This won’t actively improve the Rating, but it won’t lower it, either.
• As for the last activity of the stage, you’ll have one of two Daily Affairs to undertake. If you have the security room question from Acey again, pick “Enable the smoke alarm”, whereas, if the shady man from Mission 1 comes back, choose “Pay him” for more information. 

Stage 2:

• As soon as you start Stage 2, there will be two new Emergencies to take care of. For the Emergency at the top of the room, “Take out Guidance on Security” to remove the Zealousness effect from the final boss.
• For the second Emergency, you’ll be asked whether or not to give up your Sleep Popping Beans due to a crackdown on food and drinks at the gallery. Despite that hurdle, choose to “Use it anyway” for a positive +5 Rating. 
• Of the two remaining Daily Affairs, pick the one on the left. In response to Acey’s question, respond that you’ll “Roll it up” as an answer to how you’ll get The Football Match painting out of the gallery. 
• Just to note, you may end up losing 5 Rating points here due to not checking the ventilation ducks but, even if this happens, you’ll still come away with 100/100 points if you continue following the path for future stages.
  
  

  “Guidance” on Security

Stage 3:

• This Emergency will ask you to plan a safe route into the hall: respond with “Leave it to me!”
• With 2 AP remaining, you’ll be able to undertake both of the Daily Affairs left in Stage 3. For the curious cat Affair, “Use the Bubble Distractor” to keep it entertained. 
• On the other hand, with regards to the malfunctioning robot, opt to “Avoid it” to gain some crucial Rating points.

Stage 4:

• The first Emergency for stage 4 of The Football Match will start combat when you “Try to escape”. Don’t worry, though, as this still results in your earning Rating points. 
• As for the second Emergency, decide to “Retreat for now.”
• Lastly, you’ll once again be faced with the escape plan question for your Daily Affair. Respond the same way as last time – “Jump out of the window” – to earn some more points.

Stage 5:

• This stage starts with only one Emergency available to choose from. After clicking it, choose “Read Guidance on Security” instead of relying on Ms. Acey. This act will remove the Emergency Charge effect from the final battle.
• Then, after the next Emergency appears, choose “Replace The Football Match with a counterfeit.”
• After this, one more Emergency will pop up with only a single option available. Click it, beat down some robots and clear stage 5. 

Finally, after all that work, you’ll reach Stage 6 of The Football Match job. Before you can claim your in-game rewards and goodies, you’ll need to face the final boss of the gallery, which is a massive Security Robot called The Brain. Beat the Brain and it’s tin-man soldiers and you’ll come away the victor, hopefully with 100/100 on the mission Rating.

That was how to score 100/100 on all of the Thief of the Thieves missions in Reverse 1999.
