I basically took this mod : https://modworkshop.net/mod/22662 and removed everything except for shooting lua.

So you can use perk deck abilities (PECM, Injector and etc.) while shooting, but you can't use it when driving a vehicle, using a bipod or something else.

There's a ton of players that want to use abilities while shooting, but they don't want to download the mod that allows you to use abilities in vehicles. Since it feels like a cheat or a mod that gives the player too many advantages.
