A "scrolling shooter" or "shoot em up" game inspired by the arcade classic Defender..
Zap the aliens with your laser gun whist avoiding their bullets. If things get really tight you can employ your smart-bombs and kill everything in sight.
The aliens come in four different varieties:
1. Infantry... the troops, they shoot at you.
2. Mine-layers... they deposit a trail of deadly mines.
3. Emergers.... these come out of nowhere and start rapid fire shooting.
4. Exploders!... if you shoot one of these they die with a last-gasp spray of bullets!
Defender Force employs a unique move-and-shoot mechanism that allows the user to play the game with just one finger. This may take a minute or two to get used to, but once mastered, you'll wonder why all shooters don't work this way.
Much more exciting than space invaders.
Warning: This retro shooter/space war is addictive!.
