Warthog Run

The Warthog Run is a part of both Halo:Combat Evolved's The Maw and Halo 3's Halo). It involves the [[Master Chief (or the Arbiter) driving an M12 Warthog LRV to escape an explosion to escape a Halo's destruction.

Halo:Combat Evolved Run
In Halo:Combat Evolved, you must enter a vehicle bay and select a Warthog. You must drive 2km down a Class seven Service Corridor to External Access Junction 4C, where you are to be extracted by Foehammer. However, Echo 419 is shot down by Covenant Banshees as she tries to pick up the Chief one last time. After analysing the UNSC Pillar of Autumn's inventory, Cortana tells the Chief to drive a further 1km to Launch Bay Seven, where a C709 Longsword is still docked. As the Chief arrives in Launch Bay Seven, a pile of barrels prevents the warthog from going any further. This forces the Chief to run the last 100 metres on foot. On Easy, Normal and Heroic, you will have six minutes to reach the Longsword and make your escape. However, on Legendary, you have only five.

Halo 3 Run
After activating the replacement Alpha Halo, the Master Chief and the Arbiter must drive the late Sergeant Johnson's warthog. He then must drive the warthog to the UNSC frigate Forward Unto Dawn, which is waiting some distance away, for safety reasons. However, the panels on which the Chief is driving on are being destroyed by explosions caused by the incomplete Halo firing prematurely. When the Spartan reaches the Dawn, he must accelerate to full speed and jump into the frigate's hangar bay. There is no time limit in Halo 3, but if you take too long, the panels will collapse, making it impossible to complete the run.

Changes from Halo:Combat Evolved to Halo 3

 * There is no time limit.
 * The Chief has a gunner (and a passenger, if three player co-op is selected), instead of driving without any allies.
 * The Chief does not have to leave the warthog at the end.

Trivia

 * There is a grunt easter egg in both runs, the Thirsty Grunt in Combat Evolved and the Final Grunt in Halo 3.
 * Both involve a large jump in which the player must gun the warthog's engine.
 * Halo 3's final cutscene occurs in the middle of the jump, and shows the warthog landing. It is unknown if the warthog would have made it if the cutscene did not occur.
 * The "Rex" may be viewed in Halo:Combat Evolved. The player must angle the warthog slightly to the side and enter the tunnel to view it.
