I found A BMS Weapons (Mod Version) packs on youtube, and actually its really good except the sounds are actually on low quality, and some of them were bad on goldsource, so you may use Xash3D or rechanged the sounds with the better one.
So I rig Crossbow and Squeak, to BMS steam hands, and added bloods, and here is the video
Unfortenantly I don't know who made this ports, im not sure if its the Youtuber, or somebody else
Here is the link to the Video on the youtube: Youtube.com
The video is actually spanish I think. The link to download is down in the description, and its 201 MB, with some rechanges on the sentence to spanish, so, if you dont want the sentence changes, you may just copy models, and sounds/weapons .
