All the cheats do work if your running v1.11(SP). I will look for the blood, BAR and nade mods.
Edit:
The BAR in DOA's real world mod fires really fast so you should try it. (

You also might want to try the jedi mod. It makes everything more accuate, more powerful, and fires a lot faster. (

I couldn't find the blood though. But you should try any of these: 'Real Blood', sharpBlood, [MoD], Mr. Jingles, or DaGrooves' Ultimate Gore. It all depends on how much blood you want.
