The game is simple to learn, but is very addictive. Your objective is to destroy all the fortresses on the screen by shooting laser beams at them. You control your ship by pressing the cursor keys or moving the mouse, and shoot by pressing SHIFT or left mouse button. That's all there is to the game - but that's more than enough to keep you glued to the screen. Crisp graphics, nonstop action, plenty of enemy fire from 360 degrees, and smooth gameplay make Wkobo one of the best coffee break games I have seen for action fans. There is even a neat little radar screen you can use to track where enemy ships are coming from. Highly recommended, especially if you enjoy simple-but-fun shooters. Two thumbs up!
