The picture of the massive artillery gun and the two tanks is taken from the book "My Tank is Fight!" by Zack Parsons. Go buy it, it's f*cking awesome.
I KNEW I recognized this general art style(and the jetpack sound effect)! Great job, Bubs, you're really pushing the envelope for Unity games.
Also I wouldn't even bother finishing the Crobos if I were you--if anything, it'd be better to wait for DRL's Blaster Master thing that hopefully won't be horribly crippled by a shitty overbearing physics engine.
Kills should go to the last person to hit someone within the past 2 seconds if they crash to try to avoid giving someone credit for the kill. This is being abused really hard right now.
Game is absolutely killed by the ridiculous dependency on spending real money, the way it's impossible for a newbie to get started, and the lack of campaign to help new people rack up some AP.
