The idea of fighting others online with tricked out robots gets pretty dull after a few hours. Sure, there are three ways to play, player versus player, a team battling a larger, more powerful robot, and battles in which you blow up another's base of operations. And, yes, there are loads of upgrades for your robots, even robots you can purchase, er, rent for about $10 for a year. And, yes, it's a wonder to see your robot temporarily transform into a huge, powerful behemoth ready to wreak havoc on the opposition.
Another drawback is that the game doesn't present enough of the tougher "boss" battles. A boss like CodeRed, with his very strong whirlwind attack, is fun to watch and tough to kill. Almost as awesome is Blaster, with his larger than life gun and stunning jumping attack. Unfortunately, there's just aren't enough of these tough boss opponents. The bottom line is that this MMOG can be real fun for a while, it's just not that deep. You create your Bot. You get online. You throw some punches and some bombs or raise an energy field. You kill or you die. You upgrade your Bot. Then you repeat the same process.
