Harmotion is a 2D online space shooter. It is completely free, and very easy to play. You fly around in a space ship in your half of the screen, while your opponent flies around in their half. You have a choice of 6 different ships to play. Once you start getting some wins, it starts to get addicting. While I was in the middle of writing this post, I went on to check out a few things and ended up playing it for about 15 minutes. The graphics are very good for a free game, and the sound effects aren’t bad either. When flying around you can pick up items to use against your opponent. Some of the items I have seen are missiles, shields, invincibility, and mines. It’s a great way to waste some time.
