Oh, damn, this is going to be an easy one...
Goddamn Spec Ops (don't remember which one, but it was an old one.)
Gameplay was bad, controls were clunky, game was hilariously short, and there's no motivation to do anything in the game.
It was like Call of Duty if you castrated it. And I don't even like CoD that much (but the Special Operations missions are fun as shit, though.)
