Too few Nazis - want more

[NaziHunter]

I love killing Nazis. It's just so satisfying. Being stealthy doesn't do it for me, I just want to machine-gun the goose-steppers. The Polish Surprise mission is a good one with the superman, unlimited ammo, and invisibilty cheats switched on. I like to chop 'em up good on the main staircase, and watch the ragdoll physics as they flop lifeless down the steps. Anyway, 75 Nazis is just too few. I'd prefer popping caps in a couple of hundred. How can I increase the enemy population?
