Dyno Blaze

Dyno Blaze is a cancelled beat 'em up that was in development by Bonsai Entertainment for the Genesis / Mega Drive, Mega CD and 3DO in 1994 and it would have been published by Virgin. A playable prototype of the game was somehow leaked online in 2008, in which you can try a series of (almost empty) levels where to move your rollerblade-dinosaur to fight enemies with an hockey stick. The levels are incomplete and bugged but it's possible to go trought them waiting for a bit at the end of the area and pressing the jump button.
