You get 4 people and kill a bunch of zombies together. Classic.

Lets you do a survival game with your friends, which can be fun if you enjoy slowly taking over a world/a more long-term game.

You can have fun getting 3-4 people on an airship together and owning the randos who have to play solo. Different roles mean something for everyone.

Solid 4p co-op game without much real time or skill investment needed.

it has consumed many a life

I recommend Hat Simulator for any lover of fine hats or owner of a rapidly crumbling mental state who wishes to hasten their descent into the void.
