Blitz3D 1.8

Blitz3D helps you to create 2D and 3D Games for Windows.
Blitz3D provides a simple yet powerful environment for game creation - simple, because its based around the popular and easy to use BASIC programming language; and powerful, thanks to a highly optimized underlying 2D/3D engine.

Blitz3D includes many commands to help you out with game creation - but not too many! Rather than confuse you with tons of commands, Blitz3D's command set has been carefully designed to provide maximum flexibility for minimum effort.
Blitz3D terrains can be used to generate apparently HUGE scenes! This is achieved through a trick known as LOD (level-of-detail) reduction. This completely automatic process works by picking a set of polygons which approximates the shape of a very high resolution heightmap. Blitz3D terrains can also be modified in realtime - great for blowing holes in things!
