Halley Wars — About this game
Halley Wars is a vertically scrolling space shooter with a second concern beyond keeping your own craft alive: threats that slip past can harm Earth. Sweep your beam across approaching formations, but keep an escape lane when the screen fills. Auxiliary weapons provide another way to break a dangerous situation. Before launch you can choose difficulty and the beam setting. Learn the early waves at a comfortable level, then practise choosing which target needs attention first. A tempting pickup should never draw you directly into a collision.
