Split the 58 goals into six practical groups
The official list contains fifty-eight named goals, ending with Fully Evolved for completing every achievement or collecting every trophy. Thirteen unlock for individual mission completions, four cover full-campaign difficulty, and thirteen more reward a three-Skull plus one-Terminal clean sweep in each chapter. Lore Have Mercy covers all Terminals, while Cranial, Making a Necklace, Headhunter, and Collector’s Addition measure the broader collectible hunt.
The remaining list divides into Campaign Remix, LASO, combat counters, Skull combinations, and mission-specific challenges. Finish the story once, clean the fifty-two collectibles with mission replay, then handle counters such as Grunt backpacks, Hunter backplates, vehicle parts, hijacks, Flood limbs, and headshots during ordinary cleanup. Save restriction runs for last because several explicitly fail when the player dies, restarts, uses a forbidden action, or enables a difficulty modifier.
Mix Master is a full deathless Remixed Campaign
Mix Master requires completion of an entire Remixed Campaign without dying. Campaign Remix unlocks after any three discoverable Skulls are collected and always uses Adaptation, Reload, and Armistice, while additional unlocked Skulls can be applied through the mode’s random selection. Beat the Drop is the smaller rehearsal: complete one Remixed Mission without dying before attempting the full campaign.
Use a difficulty you can survive consistently, avoid enabling extra difficulty modifiers, and treat every mission start as part of one protected run. Slow down before instant-death falls, vehicle launches, timed escapes, and Flood ambushes. Keep a precision weapon whenever Reload offers one, preserve safe long-range equipment, and let shields recover fully between pushes. The goal rewards consistency rather than speed, so a conservative checkpoint is more valuable than a risky shortcut.
Read the unusual goals before starting their missions
Several challenge names hide very specific requirements. Hot Streak pairs Floor Is Lava with a no-jump, no-death completion. Even Tempered asks for Halo with Temperamental active without upsetting allies. Like Old Times requires Two Betrayals with Speed Limit, Endurance Spec, Hip Fire, and Armistice; Frugal Fire combines Famine, Recession, and Johnny Ammo Seed without running dry. MYTHIC is the separate full LASO completion.
Mission challenges include a no-offense Silent Cartographer run, beating the Elite to the Banshee in Assault on the Control Room, taking no hit on the first floor of 343 Guilty Spark, and staying inside the Warthog through The Maw escape. Record the exact wording before launch and avoid unnecessary modifiers, since the official list marks some goals as blocked by difficulty modifiers. Use a dedicated Rally Point attempt only when the wording permits one.
