Ever spent three hours straight smashing plastic bricks just to realize you're still millions of studs short of unlocking that one specific version of Iron Man? It’s a grind. Honestly, the LEGO Marvel's Avengers game is massive, and while the core gameplay is a blast, the sheer volume of collectibles can feel like a second job. That’s where LEGO Avengers game codes come in. They aren't just for "cheating" in the traditional sense; they're a massive quality-of-life improvement for anyone who wants to skip the repetitive stud-farming and get straight to playing as their favorite obscure comic book heroes.
Most people think these codes are just some leftover dev tool, but they've been a staple of the TT Games formula since the very first LEGO Star Wars. In LEGO Marvel's Avengers, they serve a specific purpose: instant gratification in a world filled with literally hundreds of unlockables. You don't need to find a specific gold brick or finish a tedious side mission in Manhattan to get these specific characters. You just need to know which string of letters to punch into the terminal.
Finding the Cheat Terminal in Manhattan
So, where do you actually put these things? It’s not in the pause menu like some older games. You’ve got to actually go somewhere. You'll want to head to the S.H.I.E.L.D. Helicarrier. Once you’re on the deck, head inside to the command center. Look for the "Extras" terminal. It’s a little computer station tucked away that looks just like the ones you use to buy red bricks.
Alternatively, you can just pause the game and select "Extras" then "Enter Code." This is way faster, but some players prefer the immersion of the Helicarrier. I usually just use the pause menu because, let’s be real, navigating that Helicarrier hub can be a bit of a maze if you're in a rush.
Every Character Code You Actually Need
Let’s get into the meat of it. These codes are case-insensitive, but you’ll usually see them written in caps. They unlock a mix of heavy hitters and weird deep-cuts from the Marvel archives.
If you’re looking for the heavy armor, A33S9G gets you the Iron Man Mark 35 (Silver Centurion). It’s one of the coolest looking suits in the game, hands down. Want something a bit more agile? 2K6KLL unlocks the A-Force version of She-Hulk.
Here are a few others that save a ton of time:
- BT8S2W for Ant-Man (specifically the Scott Lang version)
- 93NN9W gets you the Detroit Steel character
- BRJ9B5 unlocks the classic Falcon
- 24B927 for the ever-menacing Iron Monger
- 6B6X6R for the Ragnarok version of Thor (not the movie version, the clone)
Then there are the weird ones. 4G3S3M unlocks Finesse, a character most casual MCU fans have probably never heard of. 95U7T8 gives you Firebird. These are great for filling out that massive character grid without having to track down every single character token hidden behind a destructible wall in the Washington D.C. hub.
Why Some Codes Might Not Work for You
It's a common frustration. You type in a code, and... nothing. This usually happens for one of two reasons. First, you might already have the character. The game doesn't always give you a big flashy notification if you've already unlocked that hero through a mission. Check your character grid; if the icon is colored in, the code won't do anything.
Second, the DLC factor. Some characters are tied specifically to the Season Pass or individual packs like the Ant-Man or Civil War packs. LEGO Avengers game codes generally only work for characters included in the base game's roster. If you're trying to find a code for a character from the Agents of S.H.I.E.L.D. pack, you're out of luck. Those have to be earned through the DLC levels.
The Stud Multiplier Myth
I see this a lot on forums: people looking for "Cheat Codes" to get 2x, 4x, or 10x studs instantly. It’s a bummer, but those don't exist in code form for this specific game. Unlike some earlier LEGO titles where you could type in a six-digit string and suddenly become a billionaire, LEGO Marvel's Avengers forces you to find the Red Bricks manually.
You have to find the Collector in various levels, finish his "fetch quests," and then buy the bricks from the terminal in the Helicarrier. It’s a bit of a grind. My advice? Focus on getting the 2x Studs brick as early as possible. It’s located in the "Earth's Mightiest" level. Once you have that, the rest of the game becomes a breeze because your wealth snowballs. Using the character codes alongside the multipliers is the "pro" way to hit 100% completion without losing your mind.
Breaking Down the Roster
The roster in this game is weirdly specific. Since it focuses heavily on Avengers and Age of Ultron, you get a lot of variations of the core team. But the codes help you bridge the gap to the comic book side of things. Using K66TQP for The Protector or 6397S4 for Speed helps fill out those obscure teams like the Young Avengers.

It’s actually kinda cool how deep they went. Most kids playing this today might not know who Count Nefaria is (Q93SMC), but having him in the roster makes the game feel more like a love letter to Marvel history than just a movie tie-in.
Maximizing Your Gameplay Efficiency
If you're starting a new save, don't wait. Enter these codes the moment you finish the first level. Having access to a flyer like Falcon or a heavy hitter like Iron Monger early on makes the "Free Play" segments much easier. You won't have to keep switching characters as often because you'll have a versatile team right from the jump.
Basically, the strategy is simple:
- Complete the first story mission.
- Open the Extras menu.
- Plug in all the character codes.
- Go to the Manhattan hub and start hunting for those Red Brick multipliers.
The game is designed to be played multiple times. You play the story once to see the cinematic stuff, then you play Free Play to actually "beat" the game. These codes are your shortcut to the second half of that equation. They don't disable trophies or achievements, which is a huge relief. You can still get that Platinum trophy even if you use every single code on this list.

Actionable Next Steps for 100% Completion
Start by unlocking the Silver Centurion (A33S9G). This suit is incredibly versatile for early-game puzzles because it handles both silver LEGO objects and flying. Next, prioritize the Red Bricks over characters. While the character codes are great, they don't help you buy the expensive vehicles or the truly top-tier heroes like Stan Lee. Use the codes to get a functional team, then use that team to farm the 2x, 4x, and 6x multipliers.
Check your progress in the trophy room often. If a character code didn't trigger an unlock, it’s likely because that character is a reward for a specific "Character Lead" in the hub world. Stick to the codes provided in the terminal, and you'll shave about five to ten hours off your total playtime. Focus on Manhattan last; it’s the biggest time sink and is much easier once you have a full roster of powered-up characters.
