Minecraft

Minecraft is a survival sandbox video game developed by and released in 2011. The player can freely change the playable character's appearance, also known as skins, in the game to anything they desire on the Microsoft Windows and versions, but when the console versions released in 2012 and later, Mojang and Microsoft decided to release free and paid DLC skins and textures for the players to enjoy, including a handful of skins based on Rare's IPs.

Halloween Charity Skin Pack
The "Halloween Charity Skin Pack" was a downloadable skin pack for charity that was made available from October 26th, 2012 to November 26th, 2012 and included many Halloween-themed skins. It cost 1.99$ USD, with all proceeds going to charity. The pack featured three skins based on Rare's games, them being of Gregg the Grim Reaper from Conker's Bad Fur Day, the Ancient Mummy from Grabbed by the Ghoulies, and a Zippy Zombie from Kinect Sports.

On October 23rd, 2015, Microsoft released the "Halloween Mash-up pack", which brought back the skins from the "Halloween Charity Skin Pack".
