Hints

Defeating Engineers

In order to take down an Engineer quickly, use the Covenant pistol. Fully charge it to take down Engineers with one shot. This applies to both Firefight, and Campaign modes.

Finding secret doors

While using VISR mode as the Rookie, look out for secret doorways. Accessible doors will turn the amber outlines of objects in front of them blue. This is easiest to see on your weapon. Watch for them because many of these doors hide data terminals.

Data Hive: 30th audio file

The 30th (last) audio file for Sadie's Story is not in the "Mombasa Streets" but rather in the "Data Hive" level (also played by the Rookie). However, it will be in a locked area until you find the 29 audio files in the Mombasa Streets. Once you find those files, play the mission "Data Hive" until you reach the hole to get to Sub-station 9. If you found the previous files, instead of the Superintentation closing off the hole so your cop teammate cannot get through (and ultimately get killed by Drones), he will climb down the hole with you. Continue playing until the cop says something similar to "Wait here, I need to go check something." Follow him and he will reveal his true purpose for coming here and will fight you. During or after the fight, you can scan the phone on the wall next to the dead body to find the 30th audio file. Note, finding the audio file will slightly alter the scene, specifically the part where DARE and the Rookie finds Vergil. Instead of DARE telling the Rookie not to shoot, the Rookie will tell DARE not to fire and instead whistle for Vergil to come out.

Mombasa Streets: Audio Logs

The units you can get Audio Logs from in the Mombasa Streets level all have a picture of the Superintendent on them (the green smiley with white eyes and no mouth).

Uplift Reserve: Strange Marine dialogue

Created by LaYZaY78.

Play through the mission as usual until you go up towards a hill to meet a large purple platform, with a good number Of covenant around and in it. Drive or walk around the left side of it to meet a dipped down curve with a few Marines taking cover in it. Look for a Warthog. Behind it, look for a Marine talking to another wounded Marine on the ground. Turn up the volume so you can hear the conversation clearly. It sounds like the wounded Marine is talking about being animals in a cage, and the Covenant as if they were the predators. The conversation soon stops after awhile.

Halo 2 reference

In the "Prepare To Drop" mission , when the Carrier jumps to Slipspace Rupture, closely look at the right of the Carrier. You will see the Amber Clad of Commander Keyes getting into the Slipspace Rupture along with the Carrier. In Halo 2, at the end the "Metropolis" mission cinematic, you will see the Amber Clad of Commander Miranda Keyes to the right of the Carrier entering the Slipspace Rupture along with the Carrier. This is a true reference for the following reasons. In Halo 3: ODST, you are in New Mombasa and the Carrier is floating next to the space elevator. In Halo 2 you are also in New Mombasa, and at the beginning of the level on the bridge, you can see the space elevator and the Carrier floating next to it. In both Halo 3: ODST and Halo 2, when the Carrier jumps there will be a big EMP wave.

Easy "Both Tubes" achievement

Before boarding the Scorpion, hand your rocket launcher to any Marine riding on the tank. Note: For more mayhem, pick up the other rocket launcher from behind the tank and hand that off as well. Any kill the Marine makes counts toward the achievement. The Marine has unlimited ammunition, and will make getting the achievement much easier.

Easy "Vidmaster Challenge: Classic" achievement

• In Uplift Reserve, grab the Warthog at the beginning and load up with Marines. Shots fired from the Marines do not count, and you cannot use the e-brake or horn. Just fly through the level.
  

• This achievement requires you to finish any mission under the Legendary difficulty setting with no shots fired. E-braking or honking the horn with the Warthog counts against you. Most players just pile a group of Marines into a Warthog and let them do all the shooting. The following method works slightly faster, and is a bit easier. When you get around the first corner from the starting point, there is a small battle going on with a Wraith and a few smaller Covenant vehicles firing on a squad of UNSC forces. Hijack a Ghost from that area and boost all the way to the end of the level. The boost on the Ghost does not count as firing a shot. If your Ghost is getting trashed, there is a new one on the other end of the bridge you cross as the Space Elevator collapses. Also, you can climb the hill just after this location using the boost feature, instead of going along the path and getting shot at by the two Shade emplacements.
  

Easy "Vidmaster Challenge: Déjà Vu" achievement

Play under the Legendary difficulty setting with the Iron Skull on. Two Mongooses you can use as transport will appear inside the first open tunnel you can walk into after starting on the highway. Also accompanying the Mongooses are four rocket launchers with 999 shots. Take each piece of highway slowly and make sure to cover DARE when she gets overwhelmed.

Walkthrough

Glitches

Lost Platoon: Safe location from Covenant

Steal a chopper and ride it up the mountains. There will be a crack where you cannot see anyone and where they also cannot see you. You cannot shoot them, but they also cannot shot you. This is useful if you have an idle player in order to keep them safe.

ODSTs compared to Spartans

Spartans are humans who are like machines (as noted by Bungie, "Like a Spartan, you are half human, half machine"). Orbital Drop Shock Troopers (ODSTs) are like ordinary Marines, only they are highly trained, but they are not like Spartans. A mistake made by Bungie makes the player slightly like Spartans for the following reasons: during game play you are as tall as a Spartan when you are standing next to an ODST squad mate; you can wield a Gravity Hammer, which actually the only ones known to wield them are Spartans, Elites, and Brutes, not ODSTs; and you can melee Brutes to death, while only Spartans can do that. The melee attacks performed by people with lower ranks than Spartans do not affect Brutes at all.
