I got a kick *** random time but I don't own Halo 4 (might not buy it) or Dead Space 3 (will definitely buy it when I someday possibly can maybe dream of someday perhaps having a portion of half the money needed to buy it). I'll still add you, and you probably
own a lot more than just Halo 4 and DS3 (20k+ gamerscore), so we'll likely find a matching game to play. Message me so I can remove someone from my list (full list at the moment) if you want to add me. Regardless, good luck and game on.
