According to the trailer and description:
Morphies Law is a body morphology driven 3D Shooter. The basic rule of the game is simple: each weapon hit transfers mass from the victim's inflicted limb to the corresponding limb of the wielder of the weapon.The game's core mechanic works to level the playing field considerably. Really good players become huge targets, while bad players become much harder to hit. In addition, the mass transferring can imbue players with extra skills such as long legs being able to jump higher and big feet being good to absorb fall damage. As the trailer explains, individual body parts swap mass, which opens a world of potential silliness.
This game sounds like it may become one of the most versatile and fun shooters ever. Morphies Law is one strange looking game, but I hope its distinct gameplay helps it become as huge as the giant players in game. I'll definitely be on the look out for it as they try to get it on Steam Greenlight.
