I posted this question on the mod's page, but I haven't had a response yet. I noticed a lot of people saying this mod wasn't working properly, and one particular person said it clashes with MMM and they had to disable ACE. I'd love to try this mod out with my current game, but I have a few questions about it:

1) Is this compatible with MMM?
2) Does this work like it says it does, and does it work with melee weapons as well as guns?
3) Can I add this to an existing saved game without ruining it?
