This uses the 3D engine by taumich. I am still working on it currently. I have added the assault rifle from halo 3 (with the Reach sounds, it sounds better) have added Reach style recoil, changed the map and changed the controls to using the mouse to aim, as a variable, so you can move quickly or slowly. If you have any suggestions, please say them in the comments! Check out some of my other stuff too!
