とある科学の超電磁砲

Follow the multi-branching plot through five chapters of suspense, mystery, action, and comedy where your choices determine the outcome. When it's time to do battle, press the correct buttons displayed on the screen and watch the Railgun girls lay the hurt on their foes in awesome CG fight sequences. And of course no Railgun game would be complete without shower and swimsuit scenes! [from J-List]
