They were handing out demos of this. Just played through it at home.
Basically, you play the president of the USA, and you pilot a mech and blow the shit out of everything for some reason. Controls are 100% Halo / Mechassault, but the graphics are of the insano variety; imagine Otogi with mechs. Huge frickin weapons, the ability to demolish EVERYTHING, and weapons that will nuke entire buildings full of bad guys. Very fast and fun. YOu can dash in the air, dash into
Also, the voice acting and localization are really fucked up, but in a good way. The president says stuff like "YOU GUYS ARE ROAST CHICKEN!!!!" and then the navigator girl says "BUT YOU STILL HAVE A DELICIOUS DESSERT FOR ME!", and "Hahaha Mr President! Look at all the pretty lights on that building, TOO BAD YOU HAVE TO DESTROY EVERYTHING HAHAHAHHAHAHA!!!!", "Oh, those guys must want punishment, LETS HAVE FUN AND KILL THEM ALL HAHAHAHAHHAHAHA!"
