Halo Campaign Evolved: 343 Guilty Spark Walkthrough

Mission Overview

343 Guilty Spark is the sixth mission in Halo: Campaign Evolved. This walkthrough covers the primary objectives, enemy encounters, checkpoint locations, and the complete collectible route containing three Skulls and one Terminal. Follow the steps in order to find everything without missing any items.

Collectibles Route

The mission contains three Skulls and one Terminal. The collectibles are found in the order you would naturally encounter them during a full playthrough.

Fog Skull (Skull #1)

At the mission start, proceed past the destroyed Pelican. Locate the Covenant dropship that has crashed into a huge tree. From in front of that tree, turn back on yourself and climb the hill to the right of your approach route. At the top, move forward until you see tree roots on your right. Climb the small hill here, keeping the large tree on your right. At the top, check the small dirt mound—the Fog Skull is waiting there.

That's Just... Wrong Skull (Skull #2)

While searching the facility for Captain Keyes, the route becomes quiet and passes many dead Covenant. A human soldier will turn hostile along the main path. Kill this soldier to make him drop the That's Just... Wrong Skull. This encounter occurs naturally as you progress through the facility.

Tangent II Terminal

After encountering the Flood, the mission sends you back through the facility. During this backtrack, follow the objective marker through the right-hand door positioned between two wall symbols. Beyond that door, you'll see dead human soldiers and Shotguns on the left. Instead of continuing forward, turn right and circle to the other side of the area to find the Tangent II Terminal.

They Come Back Skull (Skull #3)

During the evacuation wait, flying laser-equipped robots join the fight against the Flood. Leave the fight area and move behind the structure ahead. Behind the structure, enter the dark forest. Use the glowing plant on the far side as your landmark. Jump behind the tree beside the glowing plant, cross the toppled tree branch, and collect the They Come Back Skull on the left after reaching the other side.

Checkpoint Locations

The mission auto-saves at key progression points. Major checkpoints occur after:

• Entering the facility for the first time
• After the first Flood encounter
• During the evacuation sequence

Combat Tips

• The early sections feature Covenant enemies; conserve ammo for the Flood encounters.
• Shotguns are effective against Flood forms; pick them up from fallen soldiers when available.
• During the evacuation, use the structure for cover while the flying robots engage the Flood.
