Corncob 3D

Pie in the Sky is a 2.5D and 3D first-person shooter engine developed Pie in the Sky Software and primarily used in the mid to late 1990s. It was also known as Power 3D and the 3D Game Creation or 3D Game Creation System engine. The engine was used in two games by the company as well as many other independent games and amateur projects after it was turned into a commercial game creator, largely because it minimized the amount of programming needed to make 3D games.
