Quake Combat+ is a refinement & continuation of Quake, SMC & Quake 1.5, built on Darkplaces, aiming to provide the ultimate Quake singleplayer combat experience and perfect the existing works without straying far from the original design/balance to retain compatibility with the many great custom-made user maps out there.
New in-game options such as:
1. Disable screenshake and vanilla recoil effect
2. Disable Quake 1.5's SNG wind-up (make it function exactly as vanilla)
3. Disable weapon auto-switching
4. TIPS display
5. Nightmare+ difficulty for veterans
