**Campaign Evolved: the achievements to check after the credits**

**Campaign Evolved: the achievements to check after the credits** The mission guides get you through the story and its collectible detours. The remaining achievements ask you to play particular sections differently, and a few settings can invalidate an attempt before you ever reach the fight. **Check two separate settings** Difficulty presets and skulls are not the same control. For an achievement that excludes presets, select **None** under the gameplay Modifier Preset setting. In co-op, everyone needs to check their settings, not just the host. Acrophobia and Bandana have additional achievement restrictions. Do not assume an achievement permits them simply because its description permits difficulty presets. For a clean challenge attempt, leave helpful optional skulls disabled unless you have confirmed that challenge's eligibility. Keep the skulls explicitly required by the achievement enabled. [Official settings guide](https://t.co/ZIjfRVCCRw) The practical approach is to write down the mission, difficulty, required skulls and forbidden actions before starting. That takes less time than discovering halfway through that the run was never eligible. **Combat totals you can finish during ordinary play** Check the actual counters before grinding anything: - Bad Gas: 100 Grunt backpacks destroyed. - Plate Tectonics: 25 Hunter backplates broken. - New Whip: ten vehicle hijacks. - Disarmed: 100 Flood parts severed. - Claims Adjuster: 50 vehicle parts broken. - Make Them Count: 100 headshot kills. These reward particular actions, not simply finishing enough missions. A destroyed vehicle is not automatically ten separate parts, and a Hunter kill is not proof you broke its backplate. Work on a missing counter deliberately, then inspect progress rather than repeating an encounter on an assumption. [Steam achievement list](https://t.co/5yL9PdZuVt) **Four mission-specific attempts** **That's My Ride:** reach the Banshee on Assault on the Control Room before its Elite pilot. Read the final-bridge section before arriving, keep the aircraft in view and commit to the approach instead of stopping to clear distant enemies first. **Arm's Length:** finish the first floor of 343 Guilty Spark without taking a hit. This is stricter than surviving or preserving health beneath your shields. Clear sightlines from cover and avoid turning every doorway into a sprint. This checklist is not claiming a verified no-hit enemy-by-enemy route. **Clean Lap:** start The Maw from its beginning. Halo Support specifically says the later rally-point start does not qualify. Complete the drive without flipping the Warthog; the achievement description concerns forced ejection. Slow down before awkward turns and landings instead of trying to correct an already overturned vehicle. [Official completion requirements](https://t.co/MAfAwCptTw) **Jiralhanae Conservationist:** do not kill rampaging Brutes in The Most Dangerous Game. That is a state-specific restriction, not a ban on every Brute kill. Avoid deliberately triggering a rampage with the chest device and then finishing the same enemy. If one enters that state, redirect your fire and watch where grenades or explosive splash will land. **The skull-combination challenges** For **Like Old Times**, replay Two Betrayals with Speed Limit, Endurance Spec, Hip Fire and Armistice. The important tactical change is that hostile factions no longer occupy one another while you slip past. Reassess an encounter before entering it; a battle that distracted enemies on your normal run may now send everyone toward you. **Even Tempered** belongs to Halo with Temperamental active. Protect your allies and keep your shots away from Marines rather than relying on their tolerance of friendly fire. **Frugal Fire** uses Famine, Recession and Johnny Ammo Seed. The goal is finishing without running out of ammunition. Reloading carelessly wastes the magazine's remaining rounds, so stop treating reload as something to press automatically after every kill. **Hot Streak** requires Floor Is Lava and a completed mission without jumping or dying. **Map Quest** requires Silent Cartographer without shooting, grenades, melee, death or a restart. A conventional combat walkthrough does not satisfy either restriction. Guides combine those last three challenges using the island's vehicle route. That is a dedicated attempt, not a shortcut I would fold into your first island playthrough. Learn the island and security-panel route first; then practice the non-attacking path before committing to the full combination. [Combined-run reference](https://t.co/Zuf2XJfhr7) **If the unlock does not appear** Check the conditions and your settings before repeating a long mission. Halo Support notes that delayed unlocks can take 24–72 hours, and split-screen Player 2 notifications may appear after returning to the menu or signing in as the primary player. A missing notification is not by itself proof that the run failed. Keep a note of what you actually completed. This closes the main cleanup checklist, but the Keyes/Marine trap, Food Critic interaction and full no-hit or combined island routes still deserve their own precise guides. Remix and LASO also need separate planning rather than a single line saying to make everything harder.
