This is a very straightforward Infinity Scenario, nothing new. Find the chip, flip the switch & kill the aliens, which always come in bunches & make life easy. Although all text is in German & lengthy, you can pick out "reactor" and the like. Pretty good use of platforms. Standard aliens too with one potential suicide area, but keep at it. Anyway, shut down the reactor, close the Bay doors, etc., etc. Can kill an afternoon, no sweat. This game is extremely clean by the way. Try it if you don't want too much of a challenge, the author did okay.
