K, I checked it out and found a couple of problems to consider fixing.
1) The custom crosshair for the shotty doesn't work in GPP for some reason. You might have to go stock on that one, but if you do I want the shotty's crosshair on the chaingun. It's the coolest one IMO.
2) The bordered HUD components are cool, but they don't look good on some HUDs. Please add an option to remove them.
3) and finally, the reddot is conflicting with the reddot in my HUD, so it kind of looks like a multicolered blob in the middle. Option to remove.
Good mod, otherwise. Now here are some sigustions
1) Steal the Mass Driver sound from WolfBr's mod. It sounds like a beast, and he used some of your components, so fair is fair.
2) Use most of the rest of WolfBr's sounds except for the rifle and the lasgun. (This is open source here.)
3) More particle effects. Didn't the 1.1 version have those along with dynamic glow, etc? Maybe you temporarialy deleted for compatability purposes.
4) Bullet holes. Black smudges make me mad.
That's about it! I realize this is a beta and I'm not a teacher telling you what to do. This is just what I would do, you might have different prioritys. Good job though! I'm going to use this and eagerly await an update.
(and how did you get it semipured?)
