Unit Availability Changes in Season 2
The most impactful Season 2 changes for most players are unit availability changes — which units left the game, which became unobtainable, and which permanent units are unaffected. This section is the definitive reference for "can I still get X?"
Left active rotation (May 9, 2026)
| Unit | What Changed | How to Obtain Now |
|---|---|---|
| Slimegunner | Season 1 exclusive — was B-tier best starter per Destructoid and Moyens.net. Now trading-only. Was duplicated (copies #3000–#145,000 deleted May 7). | Trading only (Discord Level 5 required) |
| Nox | Season 1 limited gamepass unit (399 Robux, 1,500 copies). Left rotation with Season 1. | Trading only |
| Builder | Season 1 exclusive. Post-season status at Season 1 end. | Trading only |
Permanently unobtainable (May 10, 2026)
| Unit | What Changed | How to Obtain Now |
|---|---|---|
| 1x1x1x1 | Powerhouse Paintball badge permanently disabled. Existing copies are fully functional B-tier starters. No new copies can be earned through gameplay. | Trading only (highest trade demand among unobtainables) |
Permanent units (unaffected by Season 2)
| Unit | What Changed | How to Obtain Now |
|---|---|---|
| Juggernaut, King | S-tier carries. Confirmed permanent — not affected by season transitions. | Shop / Summon (gameplay) |
| Hacker, Railgunner | A-tier DPS workhorses. Confirmed permanent. | Shop / Summon (gameplay) |
| Veteran, Musician | A-tier supports. Confirmed permanent. | Shop / Summon (gameplay) |
| Farms | Economy unit. Confirmed permanent. | Shop / Summon (gameplay) |
Season 2 new player starter: Slimegunner is no longer available through gameplay. If you started after May 9, 2026, use Mod as your primary starter unit. Mod is B-tier, cited by Destructoid and Moyens.net as a valid starter. 1x1x1x1 is also valid if you own it (unobtainable for new players, but fully functional in-game). See the how to get units guide for full obtainability status.
Noob Tower Defense Endless Mode — Strategy Guide
Endless Mode is the Season 2 no-wave-cap game mode. It operates on the same unit pool as Hard/Expert modes but with fundamentally different economy and scaling dynamics. Below is the strategy framework derived from the Noob Tower Defense best-loadout guides and tier-list mechanics.
Economy strategy
Endless Mode has no wave cap — Farm income compounds indefinitely. The economy math changes completely from finite modes: a Farm placed in wave 5 of Endless Mode generates income across potentially hundreds of waves, compared to 30–40 waves in Hard mode. The correct Endless economy is 2–3 Farms minimum, and you should never sell Farms to add a DPS slot. The income loss from removing a Farm in an indefinite-wave mode cannot be recovered.
Detection is mandatory every cycle
In finite modes, invisible enemies appear in mid-to-late waves. In Endless Mode, the enemy cycle repeats — invisible enemies appear in every cycle, not just once. A loadout that got lucky without detection in a finite run cannot survive indefinite cycles. One detection unit placed at the path entrance before DPS is the minimum — it is not optional, it is the prerequisite for any serious Endless attempt.
Carry scaling across cycles
S-tier carries (Juggernaut, King) are the correct choice for Endless Mode because their damage ceiling scales better against indefinitely increasing enemy HP. A-tier carries (Hacker, Railgunner) hit a damage floor in late cycles of Endless that S-tier carries do not. Tower Mastery investment on your carry compounds across cycles — more mastery means the carry continues to scale with enemy HP longer. If you are attempting Endless Mode with a sub-optimal carry, expect the run to end much earlier than a properly mastered S-tier.
Tower Mastery investment priority
For Endless Mode specifically, Tower Mastery matters more than for finite runs because the permanent stat bonuses compound across every wave of an infinite session. Prioritize mastery on your S-tier carry first, then your support. Destructoid rates Reaper enchant plus Tower Mastery on carries as the correct long-run investment. Unmastered S-tier carries can clear Hard mode; Endless Mode eventually demands mastery.
Endless Mode loadout framework
| Role | Recommended unit | Why for Endless Mode |
|---|---|---|
| S-tier DPS carry | Juggernaut or King | Highest cited DPS ceiling. For infinite-wave runs, sustained single-target DPS carries further than burst units. Tower Mastery investment compounds here. |
| Economy (mandatory × 2–3) | Farms | No wave cap = infinite compounding. Never sell Farms for DPS slots. Two Farms minimum; three for long sessions. Cited by all loadout guides as the Endless Mode economy backbone. |
| Support | Veteran or Musician | Support multiplier compounds with every carry upgrade across infinite waves — more valuable per cycle than in finite runs. |
| Detection (mandatory) | Detection-capable unit (check in-game for "detect" keyword) | Invisible enemies repeat every cycle in Endless Mode. Detection is not optional — invisible enemies will walk past your entire DPS lineup untouched without it. |
Season 2 Trading System — How It Works
Season 2 introduced a level-locked trading system. Trading is now the only way to obtain Season 1 exclusives, 1x1x1x1, and past event units. Understanding the system is essential for any Season 2 player aiming to build a complete roster.
How does the Season 2 trading system work?
Trading in Season 2 uses the official NTD Discord server. You must reach Discord Level 5 (Recon) to access the #trading and #trade-wls channels — this level lock was introduced on May 9, 2026 specifically to reduce scams. Trading is player-to-player: you offer units you own, the other player offers units they own, and you agree on an exchange. There is no in-game trading interface — all trades are coordinated through Discord.
What is the official values tool?
The game owner arlsky posted the official NTD values tool link in Discord on May 6, 2026. It tracks current market values for all tradeable units. Always verify values there before accepting a trade — the market shifts with new seasons and content updates. Check the values page for the current link and trading guidance.
What are the highest-value Season 2 trading assets?
The highest-value trading assets in Season 2 are unobtainable units: 1x1x1x1 (badge permanently disabled May 10, 2026) and Season 1 exclusives (Nox, Builder, Slimegunner — left rotation May 9, 2026). These units cannot be obtained through gameplay, making existing copies the only supply. Season 2 battlepass tower first copies are also expected to hold significant value.
Is trading safe in Season 2?
Trading risks exist in any player economy. The Discord Level 5 lock reduces but does not eliminate scams. Safety practices: always use the official values tool to verify trade fairness, only trade in the official #trading channel (not DMs), and keep screenshots of completed trades. Never accept a trade where the other player is rushing you.

Season 2 Progression Guide — New Player Roadmap
If you started Noob Tower Defense in Season 2, this is your complete progression roadmap from day one to Hard mode and beyond. Each step uses only confirmed Season 2 information.
| Step | Action | When |
|---|---|---|
| 1. Redeem all active codes | Open Settings, go to the Codes menu, redeem Season2, UPD4, ENDLESSDELAY, and Summer. Check the codes page for the current verified list — codes expire without notice. | Immediate — do this before your first run |
| 2. Learn with Mod (Season 2 starter) | Slimegunner is no longer available for new players. Use Mod as your Season 2 starter on Easy mode. 1x1x1x1 is also valid if you own it. Pair starter with a Farm by wave 5–7. | First session |
| 3. Build A-tier team for Normal mode | Unlock Hacker or Railgunner as your first carry upgrade. Add Veteran or Musician as support once the carry is partially upgraded. Two Farms by mid-game. | After Easy is comfortable |
| 4. Unlock S-tier carry for Hard mode | Save gems for Juggernaut or King — the top S-tier carries per Destructoid and Moyens.net. Hard mode requires S-tier carry + detection + 2+ Farms. Enchant carry with Reaper after unlock. | After Normal is comfortable |
| 5. Invest in Tower Mastery | After your carry and support are enchanted, invest Tower Mastery in Juggernaut/King first. Mastery compounds across every run — the earlier you start, the bigger the bonus when you reach Expert and Endless. | Ongoing from Hard mode onward |
| 6. Reach Discord Level 5 (Recon) | Participate in the official NTD Discord to reach Level 5 / Recon. This unlocks trading access, which is the only way to obtain Season 1 exclusives, 1x1x1x1, and any unit from ended events. | Parallel progression while grinding Hard mode |
Season 2 beginner reality check: Season 2 removed the top-rated starter (Slimegunner) from new player access. As a result, Normal mode and Hard mode take slightly longer to reach than in Season 1. This is normal — use Mod and build economy first. The permanent meta units (Juggernaut, King, Hacker, Railgunner, Veteran, Musician, Farms) are all still obtainable through gameplay. The Season 2 progression path is longer but completely viable as a free-to-play player.
Season 2 FAQ (June 2026)
Is Season 2 still active in June 2026?
Yes. Season 2 launched May 9, 2026 and is still active as of June 23, 2026. New codes (Season2, UPD4) were confirmed in June 2026 by Roblox Den, confirming the game is receiving ongoing updates within Season 2.
What happened to Slimegunner in Season 2?
Slimegunner left active rotation when Season 1 ended on May 9, 2026. It is now obtainable only through player trading (Discord Level 5 required). Copies #3000–#145,000 were also deleted as part of a dupe exploit cleanup on May 7. Legitimately obtained copies were unaffected. New Season 2 players should use Mod as their starter.
Is 1x1x1x1 still playable in Season 2?
Yes — players who own 1x1x1x1 can still use it. It remains a valid B-tier starter in Season 2. What changed: no new 1x1x1x1 can be earned through gameplay because the Powerhouse Paintball badge was permanently disabled on May 10, 2026. New players who want 1x1x1x1 must obtain it through trading.
Did the core meta change in Season 2?
No. Juggernaut, King, Hacker, Railgunner, Veteran, Musician, and Farms all retained their tier positions through the Season 1 → Season 2 transition. The meta is stable. What changed is starter availability — Slimegunner and 1x1x1x1 are no longer accessible to new players through gameplay.
Can I still get Season 1 towers in Season 2?
Only through trading. Nox, Builder, and Slimegunner left active rotation on May 9, 2026 and are now trading-only. To trade, reach Discord Level 5 (Recon) in the official NTD Discord, verify values on the official values tool, and use the #trading channel. Do not trade in DMs — it is the primary scam vector.
Are crates working in Season 2?
Crates were temporarily disabled on May 11, 2026 per server owner arlsky. Current crate status needs fresh in-game or Discord verification — check the official Discord #announcements for the latest.
What is the best Season 2 code to redeem first?
Redeem all active codes immediately — Season2, UPD4, ENDLESSDELAY, and Summer. Do not prioritize one over another; codes can expire without warning and every active code is free resources. See the codes page for the current verified full list.
