This glitch occurs on the Halo: Combat Evolved level, Halo.
At the part where you need to press the switch to activate the 'light bridge'. it is possible to skip the clip. This is how:
- Look down
- Break the glass underneath you.
- Plant a (Preferably a Plasma Grenade).
- Press X to start the cutscene.
- Instead of the cutscene starting, you will be free to move.
- If a Marine is still in combat or shooting whether with their AR or the LAAG.
Another area is in halo 3 in the covenant at the citidal where you must activate a bridge to start a cutscene with arbiter killing truth. though the cutscene still happens, you can get over to the area without activating the lightbridge.
- get to the switch
- plant a plasma grenade
- run forward
- if done correctly, you crossed it, but without using the light brige.
