Alien Force is an arcade style shooter written by Robert Epps where you pretty much blast anything that moves.
But while the rules are pretty simple, the game is anything but. Every level of the arcade game get's harder and harder. Ships in later levels get smarter and shoot more often. You have to keep moving and thinking to stay alive.
Controls:
Arrows steer the ship.
Space shoots a bullet.
S key stops the ship.
Tips:
Each ship destroyed is worth 100 points. Bonuses are awarded for level completion. The score will drop when the player does nothing so it is best to keep attacking.
Requirements:
While the game was designed for Win 3.0, it works great on 2000,XP,Vista and 7.
The game is based from an old TRS-80 game called "Attack Force".
