This article covers troubleshooting steps for achievements that do not unlock as expected in Halo: Campaign Evolved.
Overview
In some cases, achievements may not unlock immediately after their requirements have been completed. Most delayed achievements are awarded within 24 to 72 hours after completion.
If an achievement has not unlocked as expected, review the troubleshooting steps below for common conditions that can affect achievement progress and unlocks.
If you continue to have an issue with unlocking achievements, submit a Halo Support ticket.
Split-screen
While achievement progress is tracked for both players during split-screen gameplay, Player 2 may not receive achievement notifications while playing.
Player 2 achievement notifications may appear after the following actions:
- The group exits the current mission and returns to the main menu.
- Player 2 signs in to Halo: Campaign Evolved on the same console or a different console and continues as the primary player.
Skulls
Some Skulls can prevent certain achievements from unlocking while they are active. If an achievement is not unlocking as expected, check whether any achievement-blocking Skulls are turned on before attempting the achievement again.
The following Skulls prevent certain achievements from being earned:
- Acrophobia
- Bandana
To earn achievements, make sure these Skulls are turned off before playing. You can turn Skulls on or off after selecting a rally point when starting a new game.
Difficulty Modifiers
Using difficulty modifier presets prevents you from earning the following achievements and Trophies:
- Heroes Never Die — Complete the Campaign on Heroic Difficulty.
- Living Legend — Complete the Campaign on Legendary Difficulty.
- Beat the Drop — Complete a Remixed Mission without dying.
- Mix Master — Complete an entire Remixed Campaign without dying.
- Hot Streak — With the Floor Is Lava Skull activated beat a mission without jumping or dying.
- Like Old Times — Complete Two Betrayals with the Speed Limit, Endurance Spec, Hip Fire, and Armistice Skulls enabled.
- Frugal Fire — Equip Famine, Recession, and Johnny Ammo Tree Skulls and beat a mission without running out of ammo.
- MYTHIC — Complete the Campaign with LASO enabled.
- Map Quest — Complete The Silent Cartographer without shooting, using grenades, melee, dying, or restarting.
- Jiralhanae Conservationist — On The Most Dangerous Game don’t kill any rampaging Brutes.
- All Shield, No Yield — Complete any level on Heroic difficulty or higher without taking health damage.
To earn these Achievements and Trophies, turn off any difficulty modifier presets:
- Open Settings using the Menu button (XBOX controller), Options button (PlayStation® controller), or F1 (Keyboard).
- Select Gameplay.
- Under the General section at the top, select Modifier Preset.
- Select None.
Please note that all players in your Fireteam must also have presets turned off as well. For more information on using difficulty modifiers, visit our Difficulty Settings & Modifiers article.
Mission Completion
Some achievements require a mission to be completed from start to finish. Starting from a Rally Point may prevent these achievements from unlocking, even if all other requirements are met.
Example: Clean Lap
The Clean Lap achievement requires players to complete the Warthog run on The Maw without flipping the vehicle.
To unlock this achievement:
- Start The Maw from the beginning of the mission.
- Complete the mission without using a Rally Point.
- Finish the Warthog run without flipping the Warthog.
Starting from the Rally Point Charlie will not satisfy the achievement requirements.
Cross-Platform Unlocking
If you have earned achievements on one platform and are playing on another, previously earned achievements may not unlock immediately.
Please note that if you recently closed the game on another device or platform, achievement progress and account status may take time to update. Players may need to wait up to 20 minutes before signing in and trying again on a different platform.
To sync cross-platform achievement progress:
- Sign in to Halo: Campaign Evolved on the new platform using the same account.
- Perform an in-game action that can trigger achievements, like collecting a Skull or completing a mission on Legendary difficulty.
- Wait a few moments for achievement progress to synchronize.
A simple way to trigger achievements is to collect the first skull in the opening room of The Pillar of Autumn.
Additional Troubleshooting
For Steam and PlayStation® players experiencing issues with achievements unlocking on XBOX, signing out of your Microsoft account in-game and then signing back in may trigger previously earned achievements to unlock.
To sign out of Halo: Campaign Evolved:
- Open the Settings menu using the Menu button (XBOX controller), Options button (PlayStation® controller), or F1 (Keyboard).
- Select Account.
- Select Microsoft Sign Out at the top.
This will immediately sign you out of your Microsoft account in-game. The next time you reach the title screen, you will be prompted to sign in again.
For Steam players, make sure you are signed in to XBOX services through either the XBOX Game Bar or the XBOX app on Windows before signing back into the game. This can help previously earned achievements sync and unlock correctly.
XBOX Network Troubleshooting
