A problem that a lot of gun packs have imo is that they're mostly made for a single setting, and more often than not that setting is modern military. More gun packs should have stuff for other settings than just a generic modern military setting.
Also, more often than not, gun packs are either stuffty Models, good scripting/balancing, or stuffty scripting/balancing and good models, and this mod has good models (for the most part) and mediocre balancing.
Still a rad mod, though.
Why did i make this wall of text? I don't know, i just felt like it.
