Red vs Blue Radios are Easter Eggs hidden in Halo 4's Spartan Ops mode. Shooting these radios will cause them to play Red vs. Blue's opening theme. In addition, as a consequence of triggering the easter egg, dialogue from key moments of a chapter will include humorous dialogue from the series' cast. Finding one of these easter eggs will award the Roses vs Violets achievement.



Near the beginning of the level, when Fireteam Crimson comes to a bridge and must activate a power source to progress, look over the edge of the bridge's far side. The radio is on a rock near the foot of a lavafall.


At the chapter's opening, walk to the end of the corridor and go to the left. Follow the tunnel of vines and the radio is on the left wall between two vines.[1]

Shootout in Valhalla

The radio is at the very top of a pine tree at the start of the mission.[2]

Rally Point

The radio is on the right side of the waterfront tower near the top.[3]

Spartan Thorne

At the beginning of the level, turn around and look for the radio on a ledge along a cliff.[4]

Search and Destroy

The radio is hidden on top of a structure straight across from the platform on the side of the main building.[5]

Engine of Destruction

When the mission begins, follow the platform around to the left to a small control room. The radio is underneath the computer console on the right.[6]

Majestic Rescue

The radio is in an underground tunnel near the base on the far right of the map.[7]

The Hammer

Once Crimson has assisted Poker Squad, move on to the next area. Use a jetpack to get on top of the floating platform on the right. Walk to the end and the radio is sitting just over the edge.[8]

Seize the Power

After Crimson has stormed the first gate with Fireteam Forest, stick to the right side. Eventually, there will be a crashed Pelican with the radio underneath it.[9]



  • Commander Palmer: "Commander Palmer to Fireteam Castle. You're on Spartans, Dalton's got targets for you."
  • Caboose: "Um, the regular radio guy isn't here right now. Sorry."

While Crimson is defending the artifact.

  • Commander Palmer: "Fireteam Castle, this is Commander Palmer. I need an ETA on clear skies."
  • Caboose: "Seriously, the regular radio guy said he'd be right back. He's in the bathroom."


Crimson activates the first computer.

  • Caboose: "What does this button do?"
  • Church: "Caboose, don't touch anything!"
  • Caboose: "But I'm great at buttons. Oh, look at that explosion!"

Recording ends.

Crimson activates the second.

  • Church: "Oh great! You broke it!"
  • Caboose: "No. The fire broke it - ah, see? Great, now I'm on fire too now. Awesome."

Recording ends. Crimson activates the third.

  • Grif: "Hey, Simmons? What do you think this thing 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: [screaming] "I'm on fire!"
  • Simmons: "Hey, is that Caboose?"
  • Caboose: [screaming]
  • Grif: "Probably. He's on fire."
  • Caboose: [screaming] "It's like the armor! It does nothing! Ah!"[10]

Shootout in Valhala

Pelicans fly in with Mantises.

  • Simmons: "Hold tight, ground forces. We are inbound with reinforcements. Don't wanna say exactly what, but you'll like 'em!"
  • Grif: "It's giant robots."
  • Simmons: "What?! Grif! You ruined the surprise! You have no flair for the dramatic."
  • Grif: "They're in battle, idiot! How dramatic do you want it to get?"

Pelicans drop Mantises.[11]

Rally Point

When Crimson reaches the waterfront tower.

  • Vic: "Hello? Hello? Commander Palmer, hello? Do you read me?"


  • Commander Palmer: "What are you even doing?"


  • Vic: "Oh, come on, dude! I thought you saved my number at the party last night. You were really killin' it at the karaoke. If you know what I'm sayin', dude."


  • Commander Palmer: "Miller? Status?"
  • Miller: "Working on it, Commander."


  • Vic: "Yeesh! Easy there, Commander Buzzkill. I'm going to 80's night tomorrow, so hey. Give me a buzz after you save the universe and all that. Hasta luego. Luego bye bye."[12]

Spartan Thorne

When the equipment drop comes.

  • Sarge: "I heard you boys wanted a lift, but all I've got are these guns. I suppose you could assemble some sort of primitive gun-like vehicle out of the parts... But who knows what the insurance rate would be on that bad boy."

Several gravity hammers marked "Sports equipment" are dropped.

  • Sarge: "Dammit, Grif! You dropped your cargo! Now how are we supposed to play Grifball?"
  • Grif: "I think the bigger question here might be why a military vehicle was sent into battle with sports equipment?"[13]

Search and Destroy

After Crimson has reached the nukes.

  • Sarge: (mocking voice) "This is Corporal Switchback to Infinity!"
  • Commander Palmer: "Go ahead, Switchback."
  • Sarge: "Hey Infinity, is your slipspace drive running? Because you'd better go catch it!"
  • Commander Palmer: "Crimson, you're the closest responder. Fall out and help Switchback."
  • Grif: "Babba booey! Babba booey!"[14]

Engine of Destruction

When Crimson disables the warhead in the server room.

  • Simmons: "Private Simmons to Command! There was a huge firefight down here, and engine's all shot up! I need Maintenance ASAP!"
  • Miller: "Keep it together, marine. Spartans are on their way."
  • Simmons: (sarcastically) "Oh, great! More people with guns! I'm sure THAT'LL fix the engine!"[15]

Majestic Rescue

When the equipment drop comes.

  • Miller: "I'm having Dalton drop some extra gear for you now."
  • Caboose: "Six crates of elbow grease and headlight fluid inbound now."[16]

The Hammer

After Crimson activates a Hawk squad IFF tag.

  • Roland: "Alright, I've got a recording from a Hawk IFF tag, playing it now."
  • Elite: (speaking Sangheili)
  • Church: "Yeah, I have absolutely no idea what you just said."
  • Elite:' (speaking Sangheili)
  • Church: "Dude, listen to me! I do not speak alien!"

Plasma fire.

  • Church: "Oh, this is such BS!"

Energy sword.

  • Church: "Blarg!"

Recording ends.[17]

Seize the Power

When Crimson is about to board the Lich.

  • Miller: "Crimson, I can't say I think it's sane but it's the only move we've got. Get on board the Lich by any means necessary."
  • Agent Georgia: "Cool, jetpacks. That'll help us get on that ship or my name isn't Agent Georgia."[18]
