I liked it a lot and put 50 hours into it, which was enough to finish the main campaign but not enough to max out my PC. I found the multiplayer to be unexpectedly fun, which surprised me since I usually avoid multiplayer games. The community is very open and helpful and always willing to laugh it off it someone flubs an easy shot or accidentally grenades themselves. I think the cooperative nature of the missions helps lend the in-game interactions a positive tone, as opposed to the adversarial atmosphere you get with PvP.
I won't pretend the game is for everyone, but I really enjoyed it and wouldn't hesitate to recommend it to Shadowrun fans.
