Hi all,
I just subscibed my mod to this database. I think this site is awsome. I'll tell you a bit about Infiltrate Mod.
It was started about 1 year ago to be a Singleplayer mod with just new maps and modified damage for the half-life weapons, but hey, that sucks.
We started to code, model, skin and animate. We happen to have one of the best moddelers of the world in our team (Shrike). And luckely his friend LoneWolf wanted to make some skins! See for yourself:

The code is done by [NL]Mox. For now we have implemented the following in our Apha 2.5 (for team-members only):
Weapon: USP Match By Shrike and LoneWolf
Weapon: M4A1 By Shrike
Weapon: Mossberg Shotgun By Shrike
Weapon: Maglite By Shrike
Weapon: Knife (just code)
Ammo: .45
Ammo: 5.56
Item: Bomb (also trigger_bomb)
Grunt: Multiple heads
Grunt: With Handgun
Grunt: Deathsentences
Grunt: Bleeding models
SP Level(s): Mission 1
