This is HALO 3 in a gorgeous look using reshade and rtgi ray tracing global illumination shader by pascal glicher and now it looks like it's remastered with more graphics. Weapon reflections, global illumination, CA, lens flare and lighting effects changes the feel of the game. It's sure great to play HALO 3 sometimes.
