Halo fans, brace for a new challenge: Halo Campaign Evolved has dropped a fresh wave of hidden collectibles, and the hunt is on. Polygon's latest guide reveals the exact locations of the skulls and terminals tied to the 'Boarding Action' mission, giving players a clear path to 100% completion. Whether you're a seasoned Spartan or a newcomer, this breakdown will help you snag every secret without the guesswork.

What Are the 'Boarding Action' Skulls and Terminals?

In Halo Campaign Evolved, skulls and terminals are the ultimate rewards for explorers. Skulls modify gameplay with fun or punishing twists, while terminals unlock lore-rich audiologs that deepen the campaign's story. The 'Boarding Action' mission is packed with both, but their placement is notoriously tricky—hidden behind corners, above ledges, or in the heat of battle.

Polygon's guide, published on July 30, 2026, pinpoints every single one. It's a must-read for completionists aiming to unlock all achievements and see every piece of narrative content. The guide breaks down each location step-by-step, ensuring you don't miss a single collectible.

Skull Locations in 'Boarding Action'

Skulls are the bread and butter of Halo's hidden secrets. In this mission, you'll find several, each tucked away in unexpected spots. Here's a quick rundown based on the guide:

  • Skull #1: Found early on, right after the first major firefight—look for a narrow alcove on the left side of the main corridor.
  • Skull #2: Mid-mission, after you board the enemy ship. Check the upper catwalk, behind a stack of crates.
  • Skull #3: Near the mission's climax, in a side room off the main hangar. It's easy to miss if you're rushing to the exit.

Each skull offers a unique modifier, from increased enemy aggression to reduced ammo. The guide emphasizes that patience is key—these aren't in plain sight, so take your time and sweep every corner.

Tips for Finding Skulls Faster

The Polygon guide suggests using the game's audio cues—skulls emit a faint hum when you're close. Also, keep an eye on your motion tracker; sometimes the collectible's glow can be seen through walls. If you're stuck, try lowering the difficulty to explore without pressure.

Terminal Locations in 'Boarding Action'

Terminals are equally important, offering deep lore about the Halo universe. In this mission, there are two terminals, both tied to the Covenant's activities. According to the guide:

  • Terminal #1: After the first ship-to-ship boarding sequence, head to the bridge. The terminal is on a console near the starboard window.
  • Terminal #2: In the final section, before the boss encounter, look behind a pillar in the main control room. It's partially obscured by a holographic display.

Activating these terminals triggers audio logs that expand on the conflict between the UNSC and the Covenant, adding layers to the campaign's narrative. Don't skip them—they're essential for die-hard lore fans.

Why Terminals Matter

Beyond story, terminals contribute to your overall completion percentage and may unlock bonus content. The guide notes that finding all terminals in the campaign could reward players with a special emblem or achievement, so it's worth the extra effort.

How to Use This Guide Effectively

To maximize your efficiency, Polygon recommends playing through the mission twice: once for the experience, and once for a clean sweep. On your second run, follow the guide's order—skulls first, then terminals—to avoid backtracking. Also, consider playing on Easy or Normal difficulty if you're primarily hunting collectibles, as it reduces combat interruptions.

If you're still missing a specific item, the guide advises checking the mission select screen—it tracks your progress per mission, so you can see what you've missed. And don't forget to save after each pickup; checkpoints can be finicky.

Key Takeaways

Hunting down every skull and terminal in 'Boarding Action' is no small feat, but with this guide, you're set. Here's what to remember:

  • Skulls are hidden in alcoves, catwalks, and side rooms—sweep thoroughly.
  • Terminals are near the bridge and control room—look for holograms and pillars.
  • Use audio cues and your motion tracker to locate items faster.
  • Play on lower difficulty for easy exploration, and use mission select to track progress.

Now gear up, Spartan. The secrets of Halo Campaign Evolved are waiting to be uncovered. Happy hunting!
