Undead Defense Tycoon 2 Controls and HUD

Undead Defense Tycoon 2 uses a standard Roblox character plus walk-over tycoon buttons and a TopbarPlus menu. There is no separate “build mode.” This controls page is the bind list plus the HUD traps (codes icon, Home, heli).

On foot (PC)

Action	Input

Codes redemption is currently off — how to redeem. The icon can still sit there doing nothing.

Attack Helicopter

Action	Input
Forward / back / strafe	W S A D
Ascend	E
Descend	Q
Minigun	Left click
Rockets	F

Landing = touching ground. Do not Home mid-flight unless you like taking the airframe with you — vehicles.

Console

Use the on-screen cursor for pads, TopbarPlus, and the codes panel. Fire / ADS follow your Roblox console defaults. Helis are harder; PC is the intended vehicle platform. If a pad will not eat, you are not intersecting the button volume — walk closer, do not spam jump.

Mobile

Joystick + fire button. TopbarPlus on the right can hide under thumb space; rotate into portrait/landscape if the Twitter bird is missing. Walk onto pads the same way.

HUD extras

• Kill streak / cash — top. Streaks feed care packages.
• King bar — server-wide when the boss is up.
• Group tag — after joining Box Games and rejoining.

Quality-of-life binds that are not in the game

There is no official auto-walk. Auto buy is a script feature, not a key. Shift-lock helps with shotgun Boomers. First Aid should sit on a number you can hit during King leech without opening the backpack.

If a pass or gun “does not work,” confirm you are not in the test place, then confirm the pad is actually purchased. Controls will not spawn a Super Sentry you have not reached — gamepasses.

Shift lock, third person, and Boomers

Shift lock (or first person) makes shotgun follow-through easier on Mini packs and worse if you need to see a Tough wind-up. Third person is the vehicle default. There is no aim-down-sights toggle beyond whatever the individual gun implements (AUG / Laser Rifle / Railgun scopes).

Reload is the Roblox tool reload unless the weapon is a Lab laser — those cool down instead. Do not mash R on a Photon Repeater expecting an M60 mag. Details: Weapons Lab.

Home, death, and the cursor

Home is a teleport, not a pause. Using it during King smash can save you or can strand a heli in the skybox — vehicles. After death, your camera may sit on the corpse; click back onto the character before you try to buy a pad. Console players who “cannot buy” are usually one stick-nudge short of the button volume.

Keep First Aid on 2 or 3. King leech does not wait for you to open the backpack — King Zombie.
