That’s why Call of Duty added a zombies mode so people would have content outside of the campaign. Same with Titanfall 2 and their horde defense modes. And also Halo with Firefight and Spartan Ops.

I think it’s insane that Dead Space never made an endless mode with necromorphs. Or Battlefield never made their own PvE experience.

Dang, Half-Life don't got that

At least we have Left 4 Dead and Alien Swarm.

Plus there’s probably a bazillion mods that include a horde survival mode. I wouldn’t be surprised.

The problem with books is that they end

Yeah, it's true I wish they had a free play mode

GTA games are story based games but they let you play freely too if you completed the game or haven't started any mission yet.

That's true but not allot have that
