Game overview
What you actually do in an eight-player Roblox server
Undead Defense Tycoon 2 is the live Roblox tycoon from Box Games: you claim a plot, kill roaming undead for cash, and buy walls, guns, sentries, vehicles, and a Weapons Lab while seven other players farm the same forest. Cash comes from kills, Alpha variants pay more, and the King Zombie can spawn in the map center with a server-wide health bar. Start with the beginner walkthrough, spend in the upgrade path, then check codes and the weapon tier list.

First-hour plan
Claim a plot, join Box Games, then spend cash in the order veterans use.
- 1
Join the Box Games group
Open the official links page, join group 3002493, then rejoin the experience. The Sten and the group tag only appear after a fresh session.
- 2
Claim a plot and buy walls
Follow the getting started order: pistol to SMG, then barriers so Fast Zombies stop walking into your spawn pad.
- 3
Check codes, then ignore the Twitter bird if it is grey
The codes hub tracks live strings. Redemption is currently deactivated, so do not sit in the Twitter panel hoping REMASTER1 still works.
- 4
Spend cash on the upgrade path
Use the upgrade path tool instead of buying every floor decoration. AK-47, M60, mines, and a sentry beat a painted wall.
- 5
Learn King Zombie, care packages, and vehicles
When the purple health bar appears, read how to beat the King. Streaks feed care packages; late game is the garage.

FAQ
Wiki FAQ
Quick answers to the most common questions.
Where should a new player start?
Read Getting Started, then the upgrade path. Codes are listed on Codes even while redemption is off.
Are there working Undead Defense Tycoon 2 codes?
As of the last check there are **no active codes**. Old strings such as REMASTER1 and HUMVEE sit on expired codes. Box Games turned the redeem function off.
Is this an official wiki?
No. This is a fan resource. Confirm patches in the Box Games Discord or on the Roblox experience page.
Which languages are supported?
This wiki is in English, Français, Deutsch, Español, and Português (BR). Use the two-letter switcher in the header — it stays on the same page.
Does dying wipe my tycoon?
Your purchased buttons stay. You can drop a care-package gun and a kill streak. Details are in how to play and care packages.
Is Hardcore a separate game?
Yes. Hardcore is another Box Games place with more Alpha zombies. See events and modes before you treat it as the same save.
Ready to hold the plot?
Read the beginner walkthrough, follow the upgrade path, then open codes and the weapon tier list before you dump cash on a vanity wall color.
