*COMM Data Terminals are available only during Rookie missions. These terminals have been deemed “supersecret” and cannot be shown on the Mombasa Streets map.

**Depending on how many COMM Terminals you have found, between 0 and 8 caches are now available and appear on your in-game map.

Note

This mission takes place in Districts 10, 4, and 3. All accessible districts of New Mombasa (Districts 0, 3, 4, 5, 6, 8, 9, and 10) are available to search through. The following walkthrough details the quickest path from the ONI Alpha Site to the NMPD HQ; you can head to any of the mission objectives you haven’t discovered yet, though.

Mission Objectives

  • NEW MOMBASA Search NMPD HEADQUARTERS for ODST squadmate

Choke Point 1: Rally Point and Kizingo Boulevard Revisited

Entities Encountered

  • Jackals
  • Jump-Pack Brutes
  • Brutes
  • Engineer
  • Grunts

Objective

  • NEW MOMBASA Search NMPD HEADQUARTERS for ODST squadmate

Hop back on the Mongoose, which you should have used to reach the ONI Alpha Site, and return northwest, into the ramped tunnel and back out to the Rally Point you fought through to reach your previous clue. A few Jump-Pack Brutes are likely roaming the interior of the building you exit close to [1A], so prepare to fight them. However, stay close to cover opportunities, as there’s a nasty Jackal Sniper on the rooftop to the east. Tag this annoyance when the coast is clear, but duck back into cover as you attempt to reach the northern exit heading out into District 4; the Rally Point has additional Jackals on the upper balconies to the southwest and northwest [1B]. When you’ve cleared the area or wish to flee, travel north to the gate leading to District 4.

Note

There’s a weapons cache to the northwest, adjacent to the main road, opposite the base of the stepped area. You need to have located eight COMM Terminals for this to be accessible. Inside are Magnums (4), Silenced SMGs (4), Frag Grenades (4), and Mongoose vehicles (2).

Head down the ramp and go north, into the Kizingo Boulevard area where you drove the Scorpion Tank. Enter the small plaza with the circular planter island in the middle of it [1C], pausing to grab a Health Pack from an Optican Kiosk to the south if necessary. There’s likely to be a Covenant patrol in the area; watch for the extra protection an Engineer might offer your foes. You’re following a path that’s taking you north, toward the stepped concrete planters with the building you can enter. This is where you found the disabled Gauss Turret previously (if you’re locating clues chronologically). Deal with a small group of Grunts and a Brute as you drive north [1D], disembarking from your vehicle to grab Health Packs from an Optican Kiosk just to the right (east) of the gate to District 3.

Note

There’s another weapons cache to the southwest, along the road running near the upper stepped concrete planters. You need to have located 16 COMM Terminals for this to be accessible. Inside are Rocket Launchers (2), Rocket Launcher Ammo (2), Magnums (4), Silenced SMGs (4), and Frag Grenades (4).

Choke Point 2: Roundabout and Stepped Plaza Revisited, to NMPD HQ Entrance

Entities Encountered

  • Hunter
  • Brutes
  • Jackals
  • Grunts

Drive north to the gazebo area, where the signs of the Scorpion Tank battle are still noticeable. There’s a dead Marine inside the gazebo, near an Assault Rifle you can take. Of greater importance is the likelihood of a Hunter prowling this zone [2A]; prepare your Grenades and sidestepping capabilities, and tackle (or flee from) this foe before you’re struck by its Fuel Rod Cannon. Then check the dead-end street to the northeast for a special Optican Kiosk. You can also rummage through alleyway alcoves near sealed district gates for extra Grenades. From here, you should head northwest, toward the Speed Plaza, although you can take a small detour to the northeast, driving to another weapons cache (this is a Set 2 cache), now guarded by Jump-Pack Brutes and Jackals [2B], and head toward the Covered Plaza where you first found a Scorpion Tank. However, this area is guarded by Jackal Snipers on upper balconies and well-armed and armored Grunts, Brutes, and an Engineer and is out of your way.

Instead, head northeast into the stepped plaza [2C], watching out for Jackal Snipers on the rooftop of the building to the northeast and a ground patrol of Brutes on the stepped area itself. Afterward, you can optionally head southwest, to the base of the steps, and check out an underground roundabout [2D], collecting Grenades, Health Packs, and ammunition, and scaring a group of sleeping Grunts as you go. Continue northwest, taking care not to miss the turn left (west) into the NMPD Plaza, which has a swooping sculpture in the middle of the roundabout [2E]. Inspect the area closely; a bent Sniper Rifle hanging from a wire is the next clue to find.

Note

Expect more Brute and Engineer patrols as you lollygag in this district. Unless you’re looking for COMM Terminals, press on to the NMPD Plaza to the northwest.
