**343 Guilty Spark: collect the last skull before the evacuation ends**

**343 Guilty Spark: collect the last skull before the evacuation ends** Halo: Campaign Evolved. Major story spoilers. The last collectible is outside during the evacuation defense. Don't finish the fight and then decide to explore the trees. Take that detour when the tower comes into view, while the mission is still active. **Swamp approach and Fog** Follow the swamp route past the wrecked Pelican. At the crashed Covenant dropship caught in the large tree, clear the nearby enemies and look back toward your approach. Take the uphill path, then climb the muddy bank and roots alongside the large tree. **Fog** is on the small raised mound above. Return to the marked route and enter the facility. Keep your flashlight available; the dark spaces and branching rooms are much easier to read when you can see the actual doorways. Proceed through the rooms toward Keyes. At the interior light-bridge section, use the normal side route to reach the activation control rather than trying an unnecessary object jump. **That's Just... Wrong** comes from the distressed Marine who fires at you along this route. Killing that specific Marine makes him drop the skull. Pick up the skull after it drops. **After the recording** The recording changes the mission into an escape. The first Flood attack comes through the chamber's doors, so keep room to retreat instead of standing against one waiting for it to open. Grenades can help against a clustered entrance, but do not throw them at a nearby carrier or corpse pile while standing inside the blast radius. Follow the exit route back through the facility. The original lift is no longer a usable escape: activating it reveals the wreck below. Backtrack to the alternate route rather than repeatedly trying to ride it. **Tangent II:** during this return, look for the side room opening from the light-bridge area. The doorway has wall symbols around it, and dead Marines with shotguns help identify the adjoining space. Circle around the interior wall instead of continuing directly along the escape marker; the terminal is on its other side. Take a shotgun if it suits your loadout. Destroying a combat form's body prevents the same intact corpse from being reanimated while you are busy with another enemy. Watch the floor as well as the doorway. Continue to the working lift and return to the swamp with the Marines. **They Come Back and the final defense** At the large tower, when the objective is to hold out for evacuation, go around the structure's right side into the woods. Use the glowing plants to stay oriented and find the fallen tree. Cross along it to the rock on the far side for **They Come Back**. Do this before clearing the entire final encounter. Return to the defense afterward and finish the remaining threats to trigger the ending. The mission's list is **Fog, That's Just... Wrong, Tangent II, and They Come Back**. Neither the first lift nor the final tower uses the old Anniversary terminal route; this is the remake's collection path.
