Halo: Combat Evolved - Cheats and Easter Eggs

Halo Combat Evolved is the PC version of the famous first person shooter that saw the light of day exclusively on the Xbox console. Through the entire life of Xbox, Halo and Halo 2 remained amongst the best games ever to be developed. This first game was so good that it managed to push the Xbox sells all by itself but on the PC platform, where all the players are much harsher critics and the competition is a lot closer, a place on the podium was harder to obtain. It came with a great science fiction story and a solid gameplay with very few bugs and the only problems were some memory leaks but they were later corrected through patches. Halo Combat Evolved is relatively easy but there are some points where we could use some of the following cheats:

Survive Almost any Drop With any Vehicle
Immediately before you go off any high drop, send your vehicle into a 360 circle turn. This works best with the Warthog or Ghost. You can fall an incredible distance and receive no damage.

Skip over half of fifth level (Assault of the Control Room)
Right when you start the part of the level called, "If I had a super weapon..." (about 2/3 of the way through the level), you are supposed to get to the top of the pyramid structure on the other side, and the way the game wants you to do it is to get all the way to the bottom of the pyramid and fight your way to the stop. You can save lots of time by using the following trick: as soon as this portion of the level starts, run out onto the bridge that connects the two sides of the chasm and get into the nearest Banshee. You have to do this very quickly, or the Elites will take them first, and ruin your chance to get it. Once you're in it, just fly your way to the top of the pyramid structure and save about 20 to 30 minutes of time.

Secret room:
Go to the Red base and walk into the corner where there is a group of rocks. You will go through a secret teleporter and find yourself under the bridge. Once there, look around for a trench. Get in it, and look for a small corner with a shotgun in it. Walk into that corner and you will find the secret room. There are rocket launchers, snipers, active ammo, grenades, and overshields, along with a few pictures and a list of the beta testers.
