Hardest hard badge I've ever seen. Deserves to be an impossible, at least! So far, out of over 100,000 people who have played this game, only 100 of them have the badge.
So, I maxed out my stats after 7 minutes. Now I am sitting on a ton of XP with nothing to spend it on... Needs more upgrades. The game was dead easy, up until the upgrades ran out and the enemies didn't... which lasted until I realised that if you stand next to the right hand edge, NOBODY SPAWNS. In a survival game, this kind of defeats the purpose...
