The updated and until now unreleased M5 version of the MelPyth mod introduces three new weapons--the sniper rifle, revolver, and M79 grenade launcher--and a revised version of the shotgun from M4. The files for a combi-stick are also in the mod but it is not yet known how to make it available if at all. I also demonstrate a new command that provides explosive tipped rounds to certain marine weapons.
A million thanks to Melanikus for making this available!
This video was recorded with Fraps on a 2004 Dell computer. To get this mod to work properly, you will need an old computer with AvP Gold on it. You can technically install it to your AvP Classic folder but you'll only be able to experiment with these weapons with the Image Intensifier on because of a graphical incompatibility with newer graphics cards and the old version of DirectX.
The MelPyth mod was made by astro_muppet and Melanikus. M5 dates to 2007 and is available here: Indiedb.com
