Monster Dunk is a cancelled arcade basketball game that was in development by Mindscape Inc for the Nintendo 64, as a part of Nintendo’s “dream team” of developers that were working on titles for their “Project Reality”. It seems that the game was announced at E3 1995 but the developers never shared any official screenshot, even if the project could have been at least in a concept / prototype form, maybe if we are lucky some images could resurface some day.
In the original press release we can read:
The game takes a unique and humorous twist on the basketball game genre, featuring famous monsters playing two-on-two basketball. “Monster Dunk” will take advantage of Nintendo Ultra 64′s unique capabilities, such as providing players with dozens of stunning special-effects moves (for example, one character becoming a cloud of smoke, morphing into a bat, flying above the basket and dropping the ball through), creating dozens of random court hazards (hands periodically reaching up from the floor and grabbing players’ legs), and including humorous game- and season-ending winning team sequences (the winning team throwing the losing team out of the stadium).
In 1996 Mindscape was in huge economic problems, with expected loss of 46 millions GBP following a loss of 6.9 millions GBP in 1995, and they decided to stop the development of Monster Dunk for the N64.
