Halo Campaign Terminal Locations Guide

This guide answers exactly where every Halo campaign terminal is located, covering the main series entries that feature them: Halo 3, Halo 3: ODST, Halo: Reach, Halo 4, Halo 5: Guardians, and Halo Infinite. You’ll get the mission names, the in-level specifics for each terminal, and the rewards for collecting them all.

What Are Campaign Terminals?

Terminals are hidden, interactive Forerunner or UNSC data consoles scattered through campaign levels. They expand the lore with text logs, audio files, or holographic cutscenes, often revealing backstory that the main plot doesn’t cover. In most games, collecting every terminal unlocks an achievement and sometimes a bonus item, like a new armor piece or a hidden cutscene. The number of terminals varies by game: Halo 3 has 7, ODST has 19 (across the hub and missions), Reach has 10, Halo 4 has 15, Halo 5 has 15, and Halo Infinite has 10.

Halo 3’s terminals are all on Normal difficulty or higher. They’re mostly tucked into corners or behind structures. Here’s where to find each one:

• Mission 1 – Sierra 117: After the first bridge fight, look in a small cave on the left before the tunnel.
• Mission 2 – Crow’s Nest: In the room with the two Warthogs, check the corner behind the ammo crates.
• Mission 3 – Tsavo Highway: In the tunnel where you first encounter the Wraith, it’s on the right side behind a pillar.

Halo 3: ODST Terminals (19 Total)

• Mission Terminals: In “Uplift Reserve,� “Kizingo Boulevard,� and “ONI Alpha Site,� each has one terminal. They’re usually in locked rooms or behind doors that require a circuit breaker.

Frequently Asked Questions

Do I need to collect terminals on a specific difficulty?

No, but some games require a minimum difficulty. Halo 3 and Reach require Normal or higher. Halo 4 and 5 don’t have a difficulty requirement, but you must play the mission to access the terminals. Halo Infinite has no difficulty requirement.

What do I get for collecting all terminals?

In most games, you get an achievement (e.g., “Terminal� in Halo 4 and 5) and a hidden cutscene or lore entry. In Halo 3, you unlock the “Marathon� symbol on your armor. In ODST, you get the “Sad Clown� ending. In Reach, you unlock the “A Monument to All Your Sins� achievement and a special armor effect.

Can I collect terminals after beating the game?

Yes, you can replay any mission via the mission select menu. Your progress is saved, so you can collect the ones you missed. In Halo Infinite, you can free-roam after the story and collect any remaining lockers.

Are terminals the same as skulls?

No. Skulls are gameplay modifiers that change difficulty or add funny effects. Terminals are lore items. They’re often in similar hidden spots, but they serve different purposes.

Why can’t I find the terminal in Halo 3’s “The Covenant�?

That terminal is notoriously tricky. It’s in the tower with the two Wraiths, but you must take the left lift to the upper level. It’s hidden behind a pillar, so you might miss it if you don’t walk to the far edge.

Do terminals carry over between playthroughs?

No, you must collect them in a single playthrough (or via mission select, which saves your progress). If you start a new game, you’ll have to collect them again.
