Off the Level

This is a rules hack for playing Slipgate Chokepoint without levels inspired by Cairn, Gamma World, and Arduin's HP system. It fully encourages changing things to suit your preferences. 

There are suggestions for both one shot play and short campaign play with only a few missions. Conversely, there  are also ideas on how to incorporate stat upgrades to characters during short campaign play. It's totally not the same as gaining levels, I swear.

One thing I've realized about this is that it forces the PCs to be even more concerned about getting better weaponry instead of gaining XP, which mirrors the FPS experience very nicely.

Kill, die, respawn, kill more, and enjoy!
