damm 139!!11 i just move around like crazy until i crash the big green one that are 1 hit ko... also the robot in zombie mode is already maxed out or only maxed according your stats in campaing mode?
Finished the game and tried with another charac the hack/glitch thing and lost the first battle and got all stages, infinite money and skill points then suddenly the flash codes crashed and the enemies had infinite HP and they died and got stuned an revived and so
Got all badges, nice game btw.
Just need more thinking about doing the equipment and leveling part.
Tip to beat the doctor: just use subversion he will at 990 hp or something so just use subversion just before he does so he will "heal" 2000k and will just kill himself.
