Aliens, crazy guns, battle, gangs, and Way more fun stuff.

Open world and guns i think thats enough.

Open world, quests, Guns, Cars, Boats, Gangs, and Shops

Guns, Battle, quest, open world, and even Flame throwers.

Its awesome it has gamemodes, workshop items, and you can make anything.

Zombies thats all i have to say "Z" "O" "M" "B" "I" "E" "S"

Most of my freinds play team Fortress 2 becuase you can fight, capture, and find items.
