So the game in question is this Voxel ish game of sorts.. I do recall it has a lot of masks/helmets in it and you can wear various helmets/masks to do things like in the funny vid in it's steam page shows a character put on a zombie mask then lead zombies to attack villagers..

I know the game is procedurally generated, and even to have quests like that.. it was over 4 years ago I saw that it was early acess so im sure its prolly not early no more. I think it has destructible environment as well as the ability to pick up anything in the world that your character is able to I sorta recall watching a video of someone throwing a npc..

The trailers for the game were goofy.. and I think they had various masks a lot of masks that were tied to "guilds"
