Me and six mechs from Achron to build me a secret underground chronoporter. I will then look around me. If there are a thousand copies of myself, each with a rocket launcher, then I will charge out and fight. If there are not, I will hide in my base for an hour, then travel back in time to a point just before my past self starts counting up how many copies of myself there are. If my past self decides to attack, I attack with him. If not, I wait with him until he travels back in time, at which point I follow him.
I think you see where this is going.
