Undead Defense Tycoon 2 Gamepass list and priority
What each Robux pass actually does on a live plot.
Undead Defense Tycoon 2 sells nine gamepasses. Prices below are the public wiki figures in Robux; Roblox can sale-tag them. Buy them after you understand getting started or you will own a Super Sentry that has nowhere to spawn.
Full list
| Pass | Price | Effect |
|---|---|---|
| Base Colorizer | R$249 | Recolor the plot |
| Vitality+ | R$299 | +25% max health |
| Agility+ | R$349 | +20% walk speed |
| Ammo+ | R$399 | +30% mag size on gun-fed weapons |
| Economics+ | R$499 | 35% chance of 2× cash per kill |
| Auto-Fill Turrets | R$599 | Free sentry refill on a timer |
| Super Sentry | R$599 | Faster, longer, fatter sentry — must reach the pad |
| Rocket Sentry | R$799 | 4-rocket volley, long range — must reach the pad |
| Flamethrower Tank | R$899 | Faster Tank, flamethrower, explodes on death |
Buy order if you spend Robux
- Economics+ if you still need Lab / heli / Devastator. It accelerates every other pad.
- Auto-Fill Turrets if you AFK with the $38k sentry — base defense.
- Super Sentry then Rocket Sentry once those pads exist.
- Ammo+ if you live on M60 / Vulcan. Useless on Lab overheat guns — Weapons Lab.
- Vitality+ / Agility+ quality of life for King leech kiting.
- Flamethrower Tank as a toy. Colorizer last.
Disclaimers people trip on
Super Sentry and Rocket Sentry do not show until the tycoon has reached those objects. The pass is not a second plot. Flamethrower Tank still pays spawn cash like other garage pulls — vehicles.
Colorizer does not add armor. Agility+ does not outrun Boomer blast radius if you melee them.
Versus scripts
Auto-Fill is the pass Box Games already sells as “do not inject an auto reload.” If a GUI offers the same thing, you are paying ban risk instead of R$599 — script safety.
Versus codes
Passes are the only reliable paid skip. Codes are empty. Do not wait for HUMVEE; buy a Humvee pad with kill cash or live without it.
Stack Economics+ with Alpha farming (8× cash) and King population scaling for the actual “I print money” build. That is still just shooting undead — how to play.
Pass stacking
Vitality+ and Agility+ both help King kites. Ammo+ plus M60 is a mag that lasts a hallway. Auto-Fill plus Super Sentry is the AFK endgame Box Games already sells. Colorizer plus nothing is a screenshot.
You do not need all nine. A free-to-play fortress is documented on the upgrade path. Passes compress time. They do not skip Lab as a heli gate — vehicles.
Refunds and test server
Roblox pass refunds are Roblox policy, not Box Games. Test server will not preview a pass you do not own, and it will not keep items. Buy on live, test on live. If a pass description says “does not show until you reach it,” believe the description — it is the Super/Rocket sentry warning copied onto this page on purpose.
Gift passes only if the recipient has the pad unlocked. Gifting Rocket Sentry to a plot still on wood walls is a delayed present.
Frequently Asked Questions
Quick answers to the most common questions.
Why is Super Sentry not in my base?
The pass only spawns the object after you reach that tycoon pad.
Does Ammo+ affect lasers?
No. Lab weapons overheat. Ammo+ is for mag guns.
Is Economics+ 2× cash always?
No. 35% chance per kill to roll double. Alphas already pay 8× before that roll.
Does Colorizer help defense?
No. It is cosmetic.
