I have just released the first tech demo of our upcoming OpenGL 3D engine Vivid3D.
It is the classic Space Invaders, but in 3D with models made in Blender3D.
You can download it for free here. It's a RAR with two exes, one of which enables bloom post processing.
Controls are.
W/A/S/D Or Left/Right/Up/Down cursor keys = Move
Space bar = Fire laser.
