Halo 5: Guardians players have received a pizza-themed gift known as the "Pizza Party" Req pack. Given by Halo developer 343 Industries, the pack includes a pepperoni pizza-themed weapon skin, Last Slice, as well as the Hot Pie banner.
The pack is to commemorate the confirmation of Halo: The Master Chief Collection for PC, which was done by referring to a pepperoni pizza. This came about when a Halo Reddit thread began following the teasing of the game. In it, a fan had stated that they’d "buy the first 343 employee that comments on this pizza if MCC for PC gets announced.” The 343 community directed got involved with the thread and agreed with the free pizza and so the delivery was set.
In the excitement of the confirmation though, fans sent so many pizzas to 343's office that community manager Brian Jarrard had made a post on Twitter to plead fans to kindly stop sending pizzas. However, in a token of their gratitude, it was announced that players will receive a complimentary Last Slice skin. To claim it, players simply have to log into the game online starting on March 17th.
On another note, it's been announced that Halo: The Master Chief Collection will be available for PC and Steam. For more info, check out our news post. To add on, a brand-new Halo game titled Halo Infinite is coming to Xbox One and PC. Further details will be discussed at E3 in June.
