I wanted to modify some of the M23 weapon sprites while staying fairly close to their original appearance. Particularly the pistol, assault rifle, and rocket launcher. The original pistol sprites mostly have had their scopes neatened up. For the other two I pulled the HD weapon sprites from the Community/Freeverse plugin and tweaked them a bit to fit. All of these end result sprites are the same size as the sprites they replace and have already been converted to the standard color table.
I did this for my own personal interest but definitely wanted to share in case anyone is interested.
