the full game is pretty fun, i got it after playing the flash version, much larger campaign and map modes.

Game trainers are programs made to modify memory of a computer game thereby modifying its behavior using addresses and values, in order to allow cheating. It can "freeze" a memory address disallowing the game from lowering or changing the information stored at that memory address e.g. health meter, ammo counter or manipulate the data at the memory addresses specified to suit the needs of the person cheating at the game.

There's a cheat engine table posted http://forum.cheatengine.org/viewtopic.php?p=5534301#5534301 that works great without having to copy/paste these AoBs.

*edit* I should note this is for the steam version I haven't tested on the online/unity one.
