Sierra 117 is the first level in Halo 3, and as such serves as an introduction to the game's weapons and enemies. Overall, the level is fairly basic.

Overview

The vast majority of enemies in the level are Grunts. Each group of hostiles is led by at least one Brute. Jackals appear infrequently, with Carbine-wielding Jackals being quite rare. Weak weapons, such as the Plasma Pistol and Paegaas Workshop Spiker, are very common. Power weapons are nearly non-existent, and scoped weapons are rare until late in the level. Vehicles, with the exception of non-drivable ones like Phantoms and Pelicans, do not appear.

Walkthrough

Walk It Off (Mission Start)

The start of the level is very linear; you should have no difficulty following the trail. When the Phantom flies overhead, you should see a high rock on the right, just the right height to be jumped onto. Go there; it will be an excellent perch in the battle that is about to ensue. Unfortunately, on Legendary, you have a pretty useless weapon set, so just use your pistol to fire upon the gold-armored Brute. As soon as the magazine is empty, get in motion. About five or six Grunts will show up from the left end of the log in pretty rapid succession. Headshot them—it should be easy, as they walk in a straight line—and finish off the Brute, assuming that the Marines haven't already taken care of him.

When that group is down, find a Plasma Pistol to dual-wield with your Magnum, and move forward until you hear the sound of another inbound Phantom. Back up and take cover behind the log, and be quick about it, or the Phantom's cannons will mow you down. As soon as the Phantom departs, move forward and take out the pack—the group of four or five Grunts led by a Brute. Take out the Brute first—it should be easy to Noob Combo him, as he is likely unaware of your presence. The Grunts will probably panic, but some may remain calm, so drop the Plasma Pistol and keep the Magnum ready. When the hostiles are all down, swap the pistol for a Brute Shot.

Alternatively, you can try to stick the Phantom's door gunner as it drops off reinforcements. If you succeed, you will easily kill three or four Grunts and secure yourself a Plasma Cannon for later use.

If you head right, near the cliffs, you will find the Blind skull. If you prefer close-range combat, you may find its massive melee damage useful.

There are two packs farther up the trail. Both are led by Brutes
