Toss the Turtle The New Cocaine
I've played some pretty addictive games here, but this is insane.
Replay value? Out the freakin' roof.
The first time I sat down and played this I went at it for over two hours and got every medal... then for some reason it didn't save any of them. However, when I played it a second time I retained the tank and all my sweet guns.
I'll be playing this for weeks.
