If you're playing with people who communicate well - the game is a lot of fun. If you're playing with people who have no idea what they are doing - and not playing their assigned roles it is not fun and more grueling.
It's terrible when someone is playing as say... the medic and playing like they are Rambo...
The monster is a lot of fun to play with at times, but really difficult to master.
I've discovered that - though she can be slow at times - the 'dog' Daisy really helps in finding the monster. She'll always go after the monster - always.
Playing as the monster, you can set 'decoy' tracks if you want by going off on a path, sneaking, and jumping to another area. If a team doesn't follow Daisy and only follows the tracks, you can get away quite quickly and evolve to the next stages even faster.
I've played enough to unlock Hyde - the second assault guy. I'll have to try him out later today because the Alpha has been extended until tomorrow!
