Now that I am learning more and more about what I can do, modding wise, I've made some really needed changes to this mod and have updated the link in the first post.

The most important one is that the Silencer kicks rear now. He won't lose half his life anymore by a pistol shot in the head and can take a very generous amount of punishment. Don't expect a godlike being though.

I also recorded the graviton shield sizzle sound from the original game and used it as a replacement for the blood/metal impact sound.

Made some other small changes, mainly the GL-303 explosion and some minor things.

1.3.1;
Silencer now sparkles blue (shield) when hit.
Other minor changes, see readme in zip.
