I keep thinking of the kamikaze guys from Serious Sam, the headless guys with bombs for hands who run towards you screaming despite having no heads.
On a related note, where's Sparkster? I never played that game either, but I heard people loved that. Why don't we have Sparkster yet? And why isn't Sparkster available on XBox Live Arcade yet despite the cool previews we got a long while back? I thought it was coming soon.
*reads, finds that there's a new trailer and preview of it on IGN, released on... April 1* it could have been ANY other day! WHY THAT DAY!? God IGN, you'll make it look like Sparkster for XBox Arcade is all a hoax.
Dynamite Headdy from looks reminds me of Plok, Aero the Acrobat (played it, too hard for me on a casual playthrough), and Rayman (only played the game for N64).
