Planet Attacker 2009 for Mac

From YSFlight:

Planet Attacker 2009 is a simple 3D flight action game. The purpose of the game is to destroy all the enemy fighters and ground objects by flying your fighter. The objects in the game are imaginary space fighter (sort of), but there is an additional configuration called "USAF version" in which the fighters and ground objects look similar to the those actually used in military. This game has originally been developed in 1991 for a Japanese PC called FM-TOWNS, manufactured by Fujitsu, which had 80386, 16MHz, and 2MB RAM. Not 2GB, 2MB. It even didn't have a floating-point processor. Therefore, I had to cut down polygon count as much as possible, and the low polygon count gives a retro-game like appearance of this game.
