Unlocking God Hard
Unlocking God Hard is pretty much the same as the console releases. On the Main Menu, with a controller, rotate the right stick fully clockwise or counter-clockwise 20 times to unlock God Hard without beating the game.
To instantly reload just hit the weapon select button again (default. 1, 2, 3) while reloading.
For example: If you have an assault rifle in your slot 1 and you are currently reloading (it says “reload” in the middle of the screen) just press 1 and you have a full magazine.
This works both when you press R to reload or when you just shoot your gun empty.
