My situation is pretty much what it says on the box: I'm stuck on the beginning of the Church level without ammo, as the previous two levels in the ruins sapped every last bullet I could spare.
I'm not the kind of guy to make 10,000 backup saves for this sort of scenario, so I have nothing to revert to. On top of this, my dumbass saved right when they noticed me, so I'm basically on a ~five second timer until Blazko becomes a leaky lead statue.
I tried cheats, but the loading exploit that turns them on automatically failed and I really don't want to install a whole launcher just to cheat one segment in a video game. Do I need to start over, or is this solvable?

I'm using RealRTCW 2.2, in case that's important.
