For me, it has to be Alien: Colonial Marines as it’s terrible due to inconsistent frame rate (moments the game ran smooth and times where lag was insane, even with the best hardware). Both player & enemy AI is crap since the combat wasn’t even that immersive plus Xenomorph AI isn’t as intimidating due to it being poorly implemented.
MIB was weird. It tried to be everything, including a point and click, action game and platformer, all with fixed camera and clunky tank controls.
It sucks at everything. There’s a hint of a mediocre point and click in there, maybe if they’d remove everything else. With the action it’s unbearable.
