I've been playing through a lot of doom mods, Brutal doom is fun. But the latest of my favorites is Project MSX. I liked it so much I made a fan film. I also recorded a later level of an awesome megawad called Hellbound. It's pretty good. Check them out!
It looks like punching things is fun ins this. D: I mean seriously, you can't EVER go wrong with punching things in the face!
