Stay in the Pelican

Staying in the Pelican can be achieved on the campaign levels Assault on the Control Room and 343 Guilty Spark in Halo: Combat Evolved.

Procedure

 * 1) When the cutscene starts to play, hold down the throw grenade button, and when the cinematic ends, you will throw a grenade and stay in the Pelican.
 * 2) Or on Assault on the Control Room you can use an alternative in which as soon as you exit the Pelican repeatedly press X (action button) or E (for PC) and you will get back in the Pelican.
 * 3) The Pelican will then fly away on it's scripted path, with you still inside
 * 4) You will eventually die when you strike the kill wall.
