I love this game - it has all the fun of TF2 (if not the balance), but it's hyoomins vs dinos, which I can't believe hasn't been a regular subject of FPS - so much more fun than shambling slackjawed zombies.
The character classes are all sufficiently interesting and different in their skillsets to keep it interesting, and the maps all have different strengths and weaknesses for both dinos and humans.
As for the lack of balance? The dinos have the upper hand in strength and agility, so humans will lose more often than not. And that's as it should be - I don't care if it's realistic or not.
Also, GIANT T-REX STOMPS ON PEOPLE AND EATS THEM ALIVE! HOW AWESOME IS THAT I ASK YOU VERY AWESOME INDEED THANKYOUVERYMUCH. The only thing more fun is tracking a wounded t-rex and emptying your magazine into him from a safe distance, so that his massive scaly weight piledrives him into a crumpled cartwheel. To think that I should have lived to see this glorious day! I can now die content, but only after I've racked up another 80 hours on this excellent shooter.
Well done Lukewarm Media.
