After struggling to get all 4 of us connected in Torchlight 2 last week, we moved on to (back to) Sanctum 2 last night. We played *Sanctum 2* 5(!) years ago and had fun, so when the 3 DLCs were on sale, we picked them up. It's a tower defense game where you build walls and add turrets to defend The Core(tm). But as an added bit of fun, you pitch in as a defender shooting at the marauding monsters. The "teamwork" in getting the defenses laid out can get exhausting, but it is fun in the end.
