Obviously still working, new progress:
*Hawk & Little Rapidfire SMG (Kriss Vector)
*Arena modshop blip and marker, basic teleport to the arena modshop (as bonus the maze bank arena interior is loaded by default and one of the entrances now has a teleport to the modshop)
*Exterior banners for arena are now loaded
*Added a check for DLC, if it's missing then it will prompt about it and the mod will be disabled
More soonTM

Animations can't be modded

@Cass Then you would have to install the whole dlc again with one slightly change
The point of patchday (and update.rpf) is to overwrite files from other archives so you wouldn't have to download whole after hours again because they made one small change, like when they edited the version.txt in update.rpf and you had to download 900mb

You can use this to your advantage and make your own patchday that will replace existing files, meaning you don't have to replace anything and your mod will be complete add-on
