Underground War 2.0 Working Codes
Like-milestone strings, 360K rewards, and what Cash actually buys
Underground War 2.0 still uses a short, like-based code list rather than a weekly influencer dump. As of 12 September 2026, the only working string we can confirm is 360K, which grants 500 Cash and 1 Free Potion. Codes never pay Robux. If a thumbnail promises Robux, a free Rocket Launcher, or an instant NUKE from a code, treat that claim as false.
The experience is capserg’s remake of Stickmasterluke’s 2008 The Underground War. It released on 1 June 2022 (place 9791603388, universe 3624423521). Version 2.8.32 was current as of 4 August 2026. Matches are free to play, 12 players, Red versus Blue, about 6v6, with R6 avatars. VIP servers are disabled, so you redeem on a public server — there is no private lobby where a dead string magically works.
Working code (September 2026)
| Code | Reward | Status |
|---|---|---|
| 360K | 500 Cash + 1 Free Potion | Working as of Sep 2026 |
Type 360K exactly: capital K, no spaces, no hash, no plus sign. The box is case-sensitive. 360k is not the same string.
Older like-milestone codes are dead. Release, 356K, 352K, 346K, 339K, 296K, 287K, and the 280K–260K band have expired. Some trackers still print 275k, 23K, and 25K as try-if-needed; those three are not confirmed. The archive, including why those lists stay wrong, is Expired Codes. Redeem the live string first, then use the archive so you stop burning HUD attempts on 356K.
How like milestones work
New codes are like-milestone strings. When the Roblox like counter on the experience crosses a round thousand, a matching code appears (360K likes → 360K). There is no published calendar and no promise of a code after every patch.
capserg has no official Trello, Discord, or socials for this experience. That is why the codes follow likes instead of a community board, and why random “daily codes” blogs go stale the week they are posted. If likes have not moved, do not expect a new string.
This hub only lists what we can confirm. We will not pad the table with guessed 370K or 400K codes before they exist.
How to redeem (short version)
- Join Underground War 2.0 on Roblox.
- After you spawn, look at the left HUD and open Codes.
- Focus the field labeled Enter code here.
- Type
360Kand press Enter.
If a listed working code fails, check case, delete trailing spaces, then rejoin a fresh server. Version 2.8.32 still uses that HUD path; a stale server can still cache an old codes state. The full PC and mobile walkthrough is How to Redeem Codes.
What Cash and potions buy
Cash is the in-match upgrade currency. You also earn it from play. NamuWiki’s scoring loop is:
- Dig 2 dirt blocks → 1 point + $1
- Kill → 7 points + $7
- Flag steal → 50 points + $50
Sportskeeda describes 1 point per broken wall. That is the same dirt-break loop, not a second payout table.
Spend Cash on four upgrades:
- Sword damage (hotbar slot 2)
- Gun cooldown (slot 1 Sniper/Gun)
- Shovel dig speed (slot 3; the shovel auto-digs when you stand near dirt)
- First Aid heal speed (HUD medkit, once per life)
The free potion from 360K is a shop consumable, not a permanent stat. The Robux shop separately sells cosmetics, kill effects, potions, and cash packs. There is no confirmed grenade gamepass and no confirmed trails pass in 2.0. The Rocket Launcher is not a code reward: it is a 350 Robux gamepass (id 49150929) that occupies slot 4 and includes a classic skin.
Before you dump 500 Cash into a random stat, use the Upgrade Planner and check the Weapons Tier List. Gun cooldown and shovel speed change how you take space. Sword damage only matters if you actually win melee trades.
Codes versus the rest of the match
A potion and 500 Cash do not capture the flag. Red versus Blue still turns on tunnels, mid control, and the steal. The NUKE sits on the HUD and at map center: when your team has enough points (the exact threshold is not published), someone interacts, a roughly 15 second countdown runs, and the opposing team dies. That can award the Launch a NUKE badge. First Aid remains once per life. Learn the loop in Getting Started so the code bump actually sticks on a live 6v6.
What codes will never give you
- Robux
- The Rocket Launcher gamepass
- A VIP server (VIP servers are disabled)
- A published nuke point threshold
- A third scoring table besides the dirt / kill / flag loop
If a video claims a code for those, it is mixing 2008 classic passes or another game.
Staying current
Recent history is one active like-milestone string at a time. When 360K replaced 356K, the older code stopped working. When likes cross the next round thousand, 360K may die the same way. Dead strings move to Expired Codes; they do not stay in the working table. Keep How to Redeem Codes bookmarked if a patch relabels the HUD.
Redeem 360K on a live public server now, then spend the Cash on purpose.
Frequently Asked Questions
Quick answers for Underground War 2.0 players.
What is the working Underground War 2.0 code right now?
As of September 2026, **360K** is the confirmed working code. It pays 500 Cash and 1 Free Potion. Enter it exactly, capital K. Older strings such as 356K belong on Expired Codes.
Do Underground War 2.0 codes give Robux?
No. Codes pay Cash and potions only. The Rocket Launcher is a 350 Robux gamepass, not a code reward. Spend Cash with the Upgrade Planner.
How do I redeem a code in-game?
Join a public server, open **Codes** on the left HUD, type the string into **Enter code here**, and press Enter. Case matters. The full PC and mobile steps are in How to Redeem Codes.
Why did 356K and Release stop working?
Codes track Roblox like milestones, not a weekly drop. When a new round-thousand string goes live, the previous one expires. capserg has no official Trello or Discord. See the Expired Codes list.
What should I buy with the 500 Cash from 360K?
Cash upgrades sword damage, gun cooldown, shovel dig speed, and First Aid heal speed. Compare weapons on the Weapons Tier List and plan spend order in the Upgrade Planner. New players should also read Getting Started.
