While you are over at humble bundles. Destiny 2 for 12 bucks is an amazing deal If you want a Halo / Borderlands / Warframe game. Picked it up a week ago and have played it non stop. The shooting mechanics in there are top notch. Very good. Feels like insurgency with how responsive it is. Has aliens though.... and laser guns... No worse than borderlands though. Has 3 person coop through all but the first opening of the game (30-40 min). We've got a group playing it from SimHQ and agw.

Us that reference link and it gives me 8 bucks credit which I've been using to gift people copies of the game that might like it.
