Block Defense Alpha Code Guardian

Nicole Lucero

Code Guardian

Personally finds and maintains every code on this page, with around-the-clock help from the rest of our Code Guardians.

Roblox Den's code tracker continually scans Roblox.com, social channels, user reports, game developer networks and other sources, and we've had 730,010 reports from players on Works, Doesn't work and new codes. But before any code is listed on our site, or marked as Expired, our Code Guardians check in-game that it works and that its rewards and requirements are right. That's why every code you try on Roblox Den works.

  1. Checks every code in-game

    Nicole tests every new Block Defense Alpha code in-game, and re-checks any code that enough players report as not working.

  2. Keeps this page up to date

    When Block Defense Alpha changes how codes are claimed, adds a new requirement or launches a new promotion, Nicole makes sure it's covered here first.

  3. Lists exact rewards and requirements

    Every code shows exactly what it gives and any level or gamepass it needs, so you know what you're getting before you redeem it.

Nicole isn't the only Code Guardian around here: Erwin and Renato check new codes for this game whenever Nicole is away or asleep.

About Block Defense Alpha

Construct a fortified base and defend it against a range of different monsters in Block Defense Alpha, a strategic survival game where you'll get to work together with other players! To get started on your first game, you'll need to select one of three game modes: easy, hard or PvP. In easy and hard, you'll find yourself placed against a range of monsters like zombies, giants and phantoms. In PvP however, you'll go head to head against another team of players, and working together with your other teammate try to withstand their series of attacks.

Depending on how many attacks you survive, you'll earn coins and XP for your character. These can then be spent on new abilities, weapon upgrades, and stronger defenses to use in future games!
