10 Video Game Achievements You Only Get For Being A JERK To Other Players
5. Empty Gesture - Portal 2
Portal 2's introduction of a co-op mode has added a whole lot of chaos to the already crazy test chambers of the Aperture Science laboratories.
Two brains thinking with portals are bound to eventually use their physics-defying guns for mischief and look for ways to screw each other over.
Which is a good thing because Portal 2 rewards the average gamer's sadistic instincts with the Empty Gesture achievement!
As the name suggests, gaining the award requires you to cause the death of your teammate as they're in the middle of emoting. To do so, you have to reach the portion of the game that introduces light bridges into the puzzles and then pull one from below your partner's feet while they're above a chasm.
The requirements of the achievement are the definition of a jerk move, especially since you're supposed to do it when your partner is trying to be friendly with you, but then again it's Portal 2.
Chances are, you're going to do it shortly after they try to kill you with another deadly puzzle mechanic.
