Game 116: AstroFire (1994), by ORT Software.
A modernized version of the classic Asteroids with fancy ray-traced images and UFO enemies that, unlike the helpless pieces of space rock, fire back at you.
There's also power-ups that give you extra firepower and to keep you alive a bit longer, if you can to get them in time.
Just as timeless as Asteroids is the program the graphics were made with: POV-Ray, which was last updated 2 years ago, 31 years after its first release!
