'''Shortcut, no enemies, and finish the level early (Co-operative)'''

'''Shortcut, no enemies, and finish the level early (Co-operative)'''

When you enter the loading bay inside the T&R, (Large room where dropships can fly in/out), head to the opposite side of the room, and look for a stack of purple boxes that is two boxes high. Put one player on top of the top box, then with the other player jump on top of the first player. Now toss a plasma grenade on his head, and jump when it explodes. If timed correctly, you should be able to jump up to the ledge above. Now proceed to your right, and you will notice a number of effects. You will have skipped a significant chunk of the level, there will be no enemies for a while, and the level will go to the cutscene before you actually complete it.

'''Shortcut, no enemies, and finish the level early (Single Player, Heroic-Legendary)'''

'''Shortcut, no enemies, and finish the level early (Single Player, Heroic-Legendary)'''

This is the same trick as above, but accomplished in Single Player mode. When you first enter the room, turn hard right and look for a small, raised, slanted, platform. Hop on the purple box near it, then hop on top of the platform. (Note: You may have to clear out the room of enemies before doing this trick). Here comes the tricky part. You will notice a small gap in the wall a foot or two above the ledge you are on; keep that in mind. Now toss a plasma grenade on the lower platform in front of you, then a frag grenade into the gap on your left. Place yourself about 5 feet away from them, and jump just as they go off (You will need to start off with full health). If performed correctly, you will be pushed up to the second floor. Proceed through the closest door and complete the level. You can see an example of this trick in Cody Miller's [http://www2.mythica.org/halo/hbo/gnf/gnf_truthandrecon.mov T&R Run] for GNF.

'''Teleport from the bottom of the map room shaft to the top (Co-op only)'''

'''Teleport from the bottom of the map room shaft to the top (Co-op only)'''

Normally, when you activate the map room in co-op mode, both players are teleported down to the map room. FrogBlast, however, found a way around this. Put one player at the top of the shaft by the platform, but don't activate the cutscene yet. Bring the other player down to the map room. Activate both the map room, and the "Shafted" cutscene up top at the same time. Because of the way cutscenes behave, both players will end up top in the end. Click here to read more about this, and see videos of it actually happening (He does the trick mentioned here at the bottom of the page).

'''Hopping the first bridge and erasing all enemies in the level (Single Player)'''

'''Hopping the first bridge and erasing all enemies in the level (Single Player)'''

At the start of the level when you come out onto the first bridge, turn left and jump off as far as possible. You should land on a ledge below with little to no damage. Now turn around and jump down to the cliff below so as to land in the sort of "V" shaped crevice in the cliff edge. Now proceed along this ledge, hop down to the rocks below and land on a slanted part so as to reduce damage taken. This is illustrated in Sean Oehrle's [http://www2.mythica.org/halo/hbo/gnf/gnf_aotcr.mov AotCR] run.

'''Hopping the first bridge and erasing all enemies in the level (Co-operative)'''

As stated above, get onto the ledge to the left of the first bridge. Now have one coop player jump off and die. With the second player (who is on the lower ledge), jump off the ledge right before the other player respawns, jump to the right so he lands on the V-shaped formation on the cliff. Watch the movie [http://files.mythica.org/halo/highimpacthalo/highspeed/doumandpat.mov here] for a better demonstration of the the whole trick.

'''Skip almost the entire level'''

'''Skip almost the entire level'''

This is a very complex trick; almost too complex to pull off and save time, but it skips such an enormous part of the level, we are including it in here. Since this is a very complicated trick, we will let the movies do the talking. Click [http://files.mythica.org/halo/highimpacthalo/highspeed/keye_epod.mov here] for a video on how to get on top of the level, and [http://files.mythica.org/halo/highimpacthalo/highspeed/keye_epod2.mov here] to get from there to the Keyes room.(Source: [http://www.internetlab.ri.cmu.edu/utfoo/mission/epod_keye1.htm Utfoo]) Note: This is theoretically possible on Single Player, but people have successfully completed this trick ([http://highspeedhalo.net/?time&id=45 Link] to a video of this preformed on Legendary)
