Ok, here is the detailed intructions about how to use the model for TWCTF 4.5:

This part here only applies if you have the pak0.pak that came with 3waveCTF 3.0, otherwise skip 
down.

First go out and get yourself an pak utility.  I suggest using winpak which is available either
by ftp our on our site.  Look in the files section to find winpak on the ThunderWalker site.
Or go to ftp://ftp.cdrom.com/pub/quake/utils/bsp_pak_tools/wpak1332.zip

Fire up winpak and open the pak0.pak file in your CTF directory.  Click extract all.  After it
extracted all the files, rename pak0.pak to pak0.bak.  

Then unzip the tw45_cl.zip in your Quake directory using either winzip or pkunzip -d.  Make sure 
you use the -d option if you're using pkunzip.  This should place a new player.mdl in the 
quake\ctf\progs directory.  Make sure that our player.mdl overwrites the one that you have.

That should do it.  If this is not clear, write me at marc@geek.net and I will attempt to create 
a more instructive document.
