Eridan played a lot of World of Warcraft when they were on the meteor — but he also played a lot of PvP shooter games (Primal Carnage, Counterstrike etc.) with Karkat and Sollux. Even though Eridan dislikes Sollux, it was a good outlet for him — especially since Eridan is such a good shot that whenever he headshot Sollux, his screams of frustration brought him great joy.

Coming from publisher Reverb Software and developer Lukewarm media is a trailer for the upcoming First-Person Shooter, Primal Carnage. The game is being sold as a Man vs. Pre-Historic Beast online deathmatch, which I imagine will be some kind of player versus dinosaur battle arena type of thing.
