So final thoughts now that the beta is over, pretty similar to what 07 posted above. It's a fun game, lots of typical Ubisoft staples in there, and I don't think I'm going to buy at release for a full $60.
I still think there is too much downtime in between rounds. They should have it where you pick your attacker class and defender class at the beginning of the round and stick with it unless you change when you are dead and waiting on the next round. Don't have the 45 second time prep in between rounds.
I see this as pretty similar to evolve, it's fun and has some interesting and new gameplay concepts, but being multiplayer only I just feel like it will get old quickly and you won't get maximum enjoyment if you don't have a group of friends to regularly squad up with.
TL : DR - Good game, but not a release day buy for me.
