Simple.  Build a robot. Move him around. Watch him kill people.  Build more robots.  It’s as awesome as it sounds.  This game with the overly long yet descriptive name is an addictive romp of destructive power with cute animations and a surprising amount of challenge.  You can unlock new robots and put together an army of robots to take out the cute little stick figures.  Destroy the stick figures.  This is what Flash was made for.
