For Pulp style games I have used my classes for Mythos and Mayhem disregarding the hit point cap at 5th level/HD.
Also of use are my rules for firearms, vehicles (land and air combat), etc. These can be found in the Mythos and Mayhem page and the Operation White Box WW2 page.
I will be re-editing the Mythos and Mayhem classes for Pulp specific posts and revamping this page with direct links to specific rules such as firearms, air combat, etc.
I am also in love with Night Owl Workshop's Raider of the Lost Artifacts game. I will be posting a few of my classes revamped for that system.
