Halo Campaign Evolved: Full Achievement/Trophy List & Roadmap
Halo Campaign Evolved has 58 achievements, and we’ve listed them all and the order in which they are the easiest to get so you can 100% the game!
Skull #1: Iron Location
The first Skull can be found after the sniper section when you reach the grav lift. Instead of going into the grav lift, you’re going to want to kill the waves of enemies (which include Hunters!)
With all the enemies dead, head behind the grav lift. There’s a cactus you can find, and just to the left of it, there’s a cliff that you’re going to want to look down. At the edge of the cliff, you can find the Skull, so drop down carefully and pick it up. Just be mindful of getting back up, as you can easily fall to your death (jump up the tree branches to the left).
This Skull makes it so that dying in co-op resets you to your last checkpoint. If you’re in solo, the entire level will restart instead.
Skull #2: Endurance Spec Location
Once you’re inside the Covenant ship, you will be tasked with locating the ship’s brig. With this as your objective, head through the unlocked doors until you reach a large room filled with enemies. Once it’s clear, return to the top floor and follow the platform so you’re facing the left side.
There’s a barrel that you can jump on top of, and then you’re going to want to run and jump on top of the purple pillar. You can’t linger, as you can easily slip and fall back down. Run and jump across all three pillars, and hold the interact button to grab the Skull that’s on the final pillar.
This Skull makes it so that UNSC vehicles cannot be damaged, providing immortality to Warthogs!
Skull #3: Foreign Location
You’re eventually going to reach a large hangar room filled with Covenant reinforcements. When you enter this room, watch the locked door on your right, as you need to kill enemies so more enemies spawn behind this locked door. When they do eventually spawn, run toward the door before it closes.
If you were fast enough, you can enter the door and follow through the corridor, where you can find a Skull on the floor, so just keep your eyes on the ground and follow the hallways until you find it.
This Skull makes it so that you cannot use weapons from another faction, so you’re locked to the weapons taken from Marines!
Terminal #1: Inquisitor
The final collectible can be found when you’re tasked with rescuing Captain Keyes (although it can be done after, too). Navigate through the rooms, and you’ll find a central room with four doors, which will all lead to prison cells.
There’s a purple railing that you can hug, and with it to your left, you will want to enter the prison cell doors directly in front of you (shown above). Inside, there’s a device to interact with to deactivate the shields, and once the shields are gone, you can interact with the Terminal in the middle cell.
