For some reason, this reminds me of WWI. But Machtkampf is German for "Power Struggle". So, I'd guess its about a power struggle occurring within - the narrator has a darker side that seems to be taking control of him/her. The narrator seems to be unable to reverse the dark side, and is in a struggle to "End this game" - to make the step to eliminate the alien force.
My favourite song on Doomsday Machine.

Anyway, that's just my interpretation.
