Better Accuracy (Bullet goes where you aim), Faster projectile speed, Better camera (With default camera the crosshair is too close to the player), Options for more Health, Better painkillers, More Ammo, !(for camera mod to work, starting a new game is required)!
Work as intended. It is easier to hit and see what you are hitting with the camera, accuracy and bullet speed modifications. It really improves the experience. My only minor problem is that foward movement does not seem to be straight at where you are aiming due to the angle, but just slightly.
Back up the files the mod overwrites, so you can roll back to the default camera or try the other one.
EDIT: I found out how to change the camera in the globalconfig.txt file provided in either the close or far camera folder. Messing with the x, y and z coordinates I was able to change it to my liking.
