Hard-Head

In 2017 a PAL copy of this game appeared on Ebay UK complete with a label. We now know that the game is called Hard-Head. Unlike most Activision games, Hard-Head has no game variations. However since this is still a WIP, game variations may have been planned later on. The left difficulty switch controls the game difficulty (A=Easy, B=Hard), while the right difficulty switch appears to control how your character climbs the blocks. Although this prototype appears to be nearly complete, there are still a few bugs in the game. It's unknown why this game never got released. One possibility is that the programmer may have left Activision before the game was completed.
