Killer Bees is an aim-and-shoot game, where the player faces swarm after swarm of... really, you can probably take an educated guess. Each wave of attack is composed of five buzzing enemies, to shoot them down, get them within your crosshair and fry your target with a pair of lasers. But don't let the title mislead you: the bees themselves are perfectly harmless. It's your energy that keeps draining away, and if you run out, it's game over.

At the end of a wave, you're scored by your remaining energy: shooting takes energy, too, so accuracy counts as much as speed. The next wave will drain your energy faster than the one before. You may pick a difficulty from 1 to 10, which determines the wave you start on.
