First of all, this is (almost) a total rip-off of Alcat101's mod "P90 Tactical modpack".
This means all credits to Alcat101, without him and his help in doing this mod i wouldnt be able to sort out meanings of all those code lines and what to edit.
What this mod does:
With new AP ammo the damage goes to a level of high-powered rifles and submachine guns, but you can carry only two of those clips now - one loaded in the gun and the other is in your back pocket. In a pinch, if you search all your other pockets realy hard you can find extra 5 bullets to load in (i wanted to delete them but the game engine wont let me). The ammo pickup was further nerfed.
So basically with this ammo P90 among the other SMGs becomes something what five-seven is among other pistols.
What this mod does in short:
Increasing damage to 80-109 depending on skills.
Decreasing total ammo to 105.
Decreasing ammo pickup into 30% of default.
The mod was tested several times with and without its original.
For everyone who does not agree with this kind of balancing: all mod's resources are open, go and edit it as your soul demands, just dont bother me with "oh but its too OP, it needs -100 accuracy and stability debuff!", i dont care. So, go do it, no one stops you.
To install this mod simply put it in Steam\steamapps\common\PAYDAY 2\assets<strong>mod_overrides
