You'd think the series couldn't get better as they went, but that'd be wrong. These games are a fun, silly adventure where you get attack by a zillion things at once and hope to come out alive in the middle of it. You've got some funky, but useful weapons that get cooler as the game progresses with your little robot buddy, and colorful and interesting levels to explore and blow up.
Try and play 1 and 2, and with this one, good luck collecting enough bolts and solving all the extras.
Talk about mayhem, there are numerous times in this game where you just hold down the fire button, spin around in a circle, and go; "Aaaaaaaaagh!"
Well, that's what I do.
