Aero the Acro-Bat [Model T-15056]

Released in August 1, 1993 in USA.

For many years David Siller had ideas for the game's character in his head. He first sketched the concept of Aero in 1992. Although Aero's early designs resemble a human acrobat, Siller always intended him to be a bat. The gameplay mechanics were partly based on Namco's Mappy series. By this time, Siller had agreed to join Sunsoft of America.

The final concept was designed by David's son Justin Siller, who was inspired by mixed themes from the 70s and 80s. Some of the enemies, items and in-levels that Siller proposed never made it in the finished game. The concept included a mission objective feature, which was not added in the original release. Originally Aero was going to be released for the original NES, but by this time 16-bit consoles were on the market, so the NES version was cancelled. Much of the game's work took place at Orange County, California. Both the SNES and Genesis versions were being worked on simultaneously, but the Genesis version was released earlier as the SNES version reached its final stages of development.
