If you miss the MP5 but prefer the HD pack, this skin is for you. While you could change a couple files yourself, this is much more accurate. Gone are the days of soldiers holding M4s that magically turn into MP5s upon death. Now you can have an MP5 sprite in your hud instead of the M4.
I spent a few good hours trying to figure out how to make a HD soldier hold an MP5 instead of an M4. So if I need to keep explaining this skin, it basically replaces the HD packs M4 with the classic valve MP5. If you tried to replace the w_9mmar or v_9mmar files, you would still see soldiers holding m4s or seeing an m4 on your hud. This pack corrects this.
