Search the indicated locations to find all seven terminals:
- Terminal 1 In Chapter 2: Requiem, you will reach a large tower near the end of the mission. Before attempting to go up it, kill the armored Hunters, and look for a main ramp leading up to the central tower's elevator shaft. Search underneath the transparent ramp to find the first terminal. Terminal 2 In Chapter 3: Forerunner, after Master Chief's screen flickers while searching for the first of two objective at the beginning of the mission, Cortana will say "What's that distortion?" The terminal will be directly ahead, on the ground floor of the central Promethean building, below a circular structure with three columns. Terminal 3 In Chapter 4: Infinity, after meeting up with the UNSC allied soldiers, there will be a cutscene. Once the cutscene ends, turn around to find the terminal. Terminal 4 In Chapter 5: Reclaimer, after getting Cortana back, you will be instructed to escape using an elevator. Before using the elevator, go down the hall to your right, as you enter the hall leading to the elevator, to find the terminal. Terminal 5 In Chapter 6: Shutdown, you will fly a Pelican to multiple locations. Once you reach the Production Tower (third tower), Cortana will say you have to locate the control room. Take the gravity elevator up, then cross the energy bridges toward the objective. Once you reach two Hunters, go back across the energy bridge you just crossed, and go to the right to reach a new platform. The terminal is on the backside of the isolated platform. Terminal 6 In Chapter 7: Composer, after killing the two Hunters, there will eventually be a long cutscene with the Dr. Tillson. Once the cutscene ends, look directly ahead for a building with "ATRIUM" written on it. Look below that building, inside a small cave formed by rocks, to find the terminal. Terminal 7 In Chapter 8: Midnight, after crash landing on the enemy ship, you will have to fight Protheans through several chambers. After entering the third room, look behind the central pillar to find the terminal.
In Multiplayer mode, summon a hologram over a recently killed enemy to tea-bag it.
In Chapter 6: Shutdown, you will be tasked with finding a Pelican at the beginning of the mission. Instead, jump down into the large cargo bay, and go left and straight to find two masked marines standing near a forklift, past a row of Warthogs. Once you find them, they will be silent at first, but eventually start talking. The first marine to speak will always be Conan O'Brien (a late-night talk show host). The second marine to speak will always be Andy Richter (Conan's sidekick and announcer). The following are the three conversations that can be heard:
Conversation 1
- Conan: This is a pretty sweet union we're in.
- Andy: It's fantastic.
- Conan: Stand near the crates, but don't ever move 'em.
- Andy: Right, right, if anyone even looks at the crates... that's a violation.
- Conan: Ah yeah.
- Conan: Don't you think rugs would warm this up a little bit?
- Andy: Absolutely, absolutely.
- Conan: Like, literally I'm not talkin' wall to wall, just five area rugs.
- Andy: Mmhmm.
- Conan: Or some oriental rugs, and y'know what? Suddenly it's a whole different vibe in here.
- Andy: Right.
- Conan: I think somethin's up.
- Andy: What?
- Conan: I think there's gonna be a war with an alien they awoke from an ancient slumber.
- Andy: Ooooh, the- wha- that is stupid.
- Conan: I know.
- Andy: I mean, I don't know much, I mostly just load crates, but that is stupid.
- Conan: Y'know, there's one thing my grandpa told me, "Never awaken an alien from an ancient slumber."
In Chapter 5: Reclaimer, after you have destroyed the alien mothership and landed in the desert below, get in a vehicle, and keep looking to the left. Eventually, you will pass a large ravine with waterfalls in the distance on the left while going through the canyons. Get out of the vehicle, and look down. Zoom in between the waterfalls in the distance to see a double rainbow. This is a reference to the Double Rainbow viral YouTube video.
In Episode 1: Chapter 5 - The Cauldron in Spartan Ops mode, pick up the DMR at the beginning of the chapter unless you have another scoped weapon. Kill the first group of enemies, then go up the ramp. There will be some physical and energy barricades. Go straight forward from the barricades, and jump onto the ledge. Look down into the lava below using a scoped weapon. There is a small box stuck in the rocks. Shoot it, and you will hear a unique sound. Then, continue through the chapter. Eventually, Red vs. Blue characters will start talking during the regular dialogue. He will say "Caboose: Um, the regular radio guy isn't here right now. Umm... sorry." and "Caboose: Seriously, the regular guy said he would be right back. He's in the bathroom."
In Episode 2: Chapter 5 - Gagarin in Spartan Ops mode, when the chapter begins, go straight, then turn left at the fork to enter a forest area. Hug the wall on the left. Once you enter an area with some yellow sacs hanging from the walls and ceiling on the left, look for a barely visible hidden box behind some plant leaves on the rocks, below the yellow sacs on the left (it is about halfway up on your left). Shoot it, and you will hear a unique sound. Then, continue through the chapter. Eventually, Red vs. Blue characters will start talking over the radio, usually after completing an objective. The following are the three conversations that can be heard:
Conversation 1
- Caboose: What does this button do?
- Church: Caboose, don't touch anything.
- Caboose: But I'm great at buttons. Hey look at that explosion.
- Church: Oh great! You broke it.
- Caboose: The fire broke it! Oh see. Oh great, now I'm on fire, too now. Awesome.
- Griff: Hey Simmons, what do you think this machine does?
- Simmons: How would I know? It's a forty-foot seamless monolith with one massive holographic button. It could be anything, from a giant microwave oven to a weapon with enough power to-
- Caboose: [Background screaming!]
- Simmons: Hey, is that Caboose?
- Grif: Probably. He's on fire.
When there are multiple Promethean Knights in an area, they can be be difficult to defeat, especially on the Legendary difficulty. To kill them easily, make sure you have a mid range weapon (battle rifle, carbine, DMR, light rifle, pistol, etc.) and the shotgun (or equivalent). Start by using your mid range weapon to shoot one of the knights in the head from a distance, but use a low rate of fire to conserve ammo. Fire only one shot every couple of seconds. This will bait him into doing the teleporting-dash across the map to melee you -- bringing him in close and separating him from the rest of the knights. When you see the knight begin to teleport-dash towards you, quickly run backwards and slightly to the side to dodge his melee attack, then switch to your shotgun and shoot him at close range. Repeat this tactic as necessary.

- Knight Helmet: Get the "Knight In White Assassination" achievement by assassinating a Knight in any Spartan Ops mission.
- UNSC Infinity Hoodie (male/female): Get the "Not Some Recruit Anymore" achievement by ranking your Spartan-IV up to SR-5.

At the beginning of the game, immediately after talking to Cortana outside the cryotube, go down the hallway, and look left to find a set of stairs leading down. Go down the stairs to find a computer. Interact with it to watch a cutscene explaining the story from the first three Halo games, and get the "Digging Up The Past" achievement.
In Chapter 6: Shutdown, you will fly a Pelican to multiple locations. Once you reach the Production Tower (third tower), Cortana will say you have to locate the control room. Take the gravity elevator up, then cross the energy bridges toward the objective. Once you reach two Hunters, stand near the ledge on the platform. When one of the Hunters run at you, use the jet pack to get out of the way. When it falls off the ledge, you will get the "Explore The Floor" achievement.
It is recommended you set the difficulty to "Easy" before attempting to get this achievement. In Chapter 7: Composer, start at the "Rally Point – Alpha" checkpoint, if you have already completed the chapter. Eventually you will find a scientist that will give you a Thruster. In the next room, you will encounter two Hunters. Run to the gun rack on the opposite side of the room; it is past the circular lowered area, and up the ramp. Grab the Sticky Detonator. If you ran ahead fast enough, the two Hunters should be unaware, allowing you to shoot at their backs. Keep shooting them in their backs with the Sticky Detonator, getting a safe distance away, and then detonating the explosives. Get close to the Hunters, and use the Thruster to get behind them so you can shoot them in the back. It should only take three to four hits to kill each Hunter on the Easy difficulty. Note: Before careful, as it is possible for the marine allies to kill the Hunters as well. If they kill one of the Hunters, you will need to restart from the previous checkpoint, and try again to get the "Give Him The Stick" achievement.
In Chapter 2: Requiem, make your way through the wreckage, and eventually you will find an overturned Warthog. Roll the vehicle over, and get in it. While driving forward, stay next to the left wall. Keep looking to the left, and eventually you will see a half-circular entrance with a ramp inside. You must jump off this ramp at midnight to get the achievement. Once you reach this point, save the game. Then, disconnect the Xbox 360 from the internet, and ensure your saved game file is on the hard drive, and not on the cloud storage. At the Xbox 360 dashboard, go to "System Settings", "Console Settings", and select "Clock, Date & Time". Set the system clock to around 11:50 p.m. to ensure you have plenty of time to reach the ramp again. Play Chapter 2: Requiem again, find the Warthog, drive it to the circular entrance. Press Xbox Guide to view the clock. Once the clock reaches midnight, drive through the entrance and up the ramp. Once you drive off the ramp, you should get the "Midnight Launch" achievement.
In Episode 1: Chapter 5 - The Cauldron in Spartan Ops mode, pick up the DMR at the beginning of the chapter unless you have another scoped weapon. Kill the first group of enemies, then go up the ramp. There will be some physical and energy barricades. Go straight forward from the barricades, and jump onto the ledge. Look down into the lava below using a scoped weapon. There is a small box stuck in the rocks. Shoot it, and you will hear a unique sound and get the "Roses vs Violets" achievement.
Play through any campaign mission on the Heroic or higher difficulty with the Cowbell, Grunt Birthday Party, and IWHBYD Skulls enabled. These three skulls do not increase the game's difficulty by too much, and count towards the "Skullduggary" achievement.
