Dodge does away with all of that, while keeping the very essence of a space shooter: Dark background, fast action, and stuff blowing up all over the place.
Your vector-looking spacecraft is the fastest thing on the screen, most of the time. And as the header implies, you have absolutely no weapons; you can't get any, either. All you have is agility and maneuverability.
Your opponents shoot heat-seeking missiles at you; the missiles lock on and start tracking you. The trick is to dodge the missiles while putting them in the path of one of your enemies, thus letting them have a taste of their own medicine.
There are three types of enemies, at least in the first few levels: "simple" spaceships which fire slow projectiles, "tanks" which seem to be more serious and take more hits to destroy, and "circles." The circles simply explode, spewing twenty or thirty very fast projectiles. This sounds dangerous, but is actually great once you learn to use them; they are very destructive for tanks, and can even blow up other circles.
The soundtrack is very techno, but it meshes very well with this type of game. Intense fun!
