Fully Automatic UPM61
Halves the fire rate and turns on automatic rate of fire. Works out of the box!
1. First and foremost, if you haven't set your launch options, do so now. 1a. Open Steam, right click Just Cause 3, click Properties, click 'Set Launch Options...', copy this:
--vfs-fs dropzone --vfs-archive patch_win64 --vfs-archive archives_win64 --vfs-archive dlc_win64 --vfs-fs .
2. Copy dropzone to your Just Cause 3 folder. 2a. If you're prompted to replace w118_assault_rifle_up_61.wtunec, chances are, you've already installed a mod that affects the UPM61 in some way. 3. Run Just Cause 3 and have fun!
