The Xbox 360 controller is also smaller, which can help with sword flying. The original Xbox loads the game extremely slowly. It is recommended to run the game on Xbox 360 due to less lag. On PAL this can save about 10 seconds over NTSC. The only known difference for speedrunning is the viability of swordflying through the glass on Oracle to reach the Banshee faster. Unlike Halo CE, Halo 2 is mostly identical between NTSC and PAL. However, manual testing by Monopoli has shown that both Halo PC and Marketplace versions have the same walking speed. It was recently discovered that the walking speed in Halo PC is apparently 12.5% slower than in the Xbox version. Due to these factors, Halo PC was the most commonly used version for speedrunning.

The aiming is more precise due to the mouse, although unlike the Xbox version there is no autoaim (sticky reticule) in Halo PC. More importantly, it has no lag during loadzones. While Halo PC has the benefit of no loading time between levels, these loads are not counted in the time anyway. Global variables showing the difference in run speed between PC and Xbox versions. For this reason it is not recommended for speedrunning. There are no known differences between the marketplace version and the original Xbox disc.ĬEA is the same game in terms of physics models, but some of the cutscene skips are slower.

Loading lag during loadzones is much shorter on 360.

Running the disc on Xbox 360 is recommended for a few reasons: There is no known difference between the original release and Game of the Year edition.

Longer fall timers (allows for different bridge drop techniques)ĭue to the difference in movement speed, PAL is the slower version and is generally poor for speedrunning.

Due to poor framerate conversion, the PAL version of Halo has: There are two main versions of the original game disc - NTSC (US/Japan) and PAL (Europe/Australia/etc). For this reason, the timing method for Halo CE was chosen to be RTA minus loads - between-level loading screens are removed from the time. Although Halo is a console series, console versions of Halo CE suffer from between-level loading screens that can add up to 5+ minutes over the course of the run.
