• Borderlands 2, specifically the mechromancer class.
    It has a perk where you get more damage each time you unload your full clip, and it resets when you manually reload.
    In PC the reload action is its own key.

    But I had a potato PC and was only able to play it at low settings. When I got a PS4 I bought the game again to play it with nice graphics. It quickly got very frustrating since the reload action is bouns to the same button as interact! So each time you tried to talk to someone, to get into a vehicle, or even pick up something from the ground you got into the risk of not aiming well enough and reloading by accident which resets your buff!
