Sierra 117 | Walkthrough Halo 3 Guide

Walk It Off

• Get to the river for evac

After regaining your consciousness, go through the jungle with the rest of team. This is a training mission, but you shouldn't forget about few rules - do not underestimate Grunts, shoot at Brutes first and don't waste your ammo. Let's start.

You will need some warm up. When you meet Grunts and a Brute kill the monkey instantly and then exterminate the rest of dwarfs. Destroy reinforcements staying on the top of the stone wall. Eliminate enemies in the usual way - first Brutes, then Grunts. Don't go any further, there is an important treasure near. Your first skull in the collection.

Blind Skull

You'll find it on the rock near the lake where you've seen the Phantom. Go right from that place and then walk straight to the edge of the cliff. You'll see a rock with a skull on it.

Effect: HUD disappears.

Beyond the cave you'll notice a group of sleeping Grunts. Go down and kill them honorably.... and don't wake them up.

The river is not too far. Next group of aliens means more ammo in your clip. If you can't find enough bullets for your Spiker, get a gun from one of the marines. On the beach you'll be attacked by a group of enemies. An accident makes the evacuation a disaster.

• Find Johnson's crashed Pelican

Well, the Pelican crashed and of course it's you, who needs to find it. Enter the buildings, killing more enemies on your way. Be careful around Brutes with Brute Shots. In the jungle you'll be attacked by Jackals, clear your way with accurate shots.

• Find Johnson before he's captured

The party's over and that big group of Grunts is fairly dangerous. Try finding a Carbine (finding Spiker ammo might be difficult), then shoot all the Jackals aiming at you from the rocks. When they're down, finish the Grunts.

Quid Pro Quo

• Rescue Johnson and his squad

Take the Sniper Rifle and shoot as much enemies as possible. Then go down and take care of the Grunts. Probably you'll run out of ammo, so don't be shy and change your weapon anytime. On the bridge take care of those Brutes and Jackals (if you don't want to fight, then you can skip the fight by taking the path beneath the bridge). On the other side you'll find a room filled with prisoners. Nothing left to do but to free them.

• Stay alive! Pelican inbound!

Fight isn't over but what you should be interested most is the next skull. Clear your surroundings of enemies and you can reach the next achievement.

Iron Skull

To get to it, you need to leave the room where you freed those marines and turn left. The go straight ahead, towards the big bridge and take the steps to reach those pipes you can see stretching along hangar windows.

Effect: If you die in solo mode, you respawn at the entrance to a given area, and not on a checkpoint. In co-op mode, if someone dies, all players return to the nearest checkpoint.
