A bit of a Necro Bump on this... I may post a new thread but this fit.
A friend of mine and I were heavy Borderlands players. Sometimes just going on the hardest levels to see how fast we could go through them (at the end). Eventually, we got bored and moved on.
Looking for more games that allow a bit of shoot-em-up or adventure multiplayer (w/o subscription) is what we are after but most seem to be single player (Bulletstorm, Fallout, Stalker) or just too involved/convoluted to enjoy on a casual basis (Magika).
Any recommendations?
