Tank...
I chose to be a mutant tank, so the second opponent cannot be won, i pushed "Repeat" for like 10 minutes, without hitting my enemy at all, the enemy wont hit me neither, and if he does, i dont take damage.
So give a slight chance of critical accuracy or something so the game could move a little for these inaccurate charecters.
Story line seems extremely fascinating as i am a post-apocalytpic fan.
