Suprise its actually not a kids game
Gameplay:
Addictive. plain and simple. Not one box went by in the level i didn't have the urge to bust open for bolts. the shooting is sound, and the upgrades and over the top weapons make charging through as entertaining as any blockbuster game i've played.
Graphics:
PS3 quality cartoon graphics, the settinga and worlds look great, the art direction even though cartoony has a great, just fun feel to them, at no point did i not feel like the setting was dark and gloomy, every world had a setting that let you know, this game is light hearted and fun, i really liked that.
Overall
I just enjoyed the game, you don't have to put much into the game. You can get home from work, throw it on, and just blast away a couple hours and want to do more. For about a week, i wanted to go home from work and keep playing that game, when i was going through Video Game A.D.D. it kept my attention, and its a pretty cheap grab now.
