Tundra Radar setup for DayZ

Game guidesDayZ Updated22 October 2026
Working Medium setup difficulty

The map opens in a browser on any device, so the window mode doesn't matter. Almost every problem comes from skipped Windows prep.

Preparation

0 of 9 steps
Remove third-party antivirus and anti-cheats Kaspersky, Avast, ESET and the like, plus FaceIT and Riot Vanguard, conflict with the loader. They must be uninstalled, not just paused.
  1. Open Settings → Apps → Installed apps (or Control Panel → Programs and Features).
  2. Uninstall any third-party antivirus (Kaspersky, Avast, AVG, ESET, 360, Malwarebytes, etc.). Pausing or disabling is not enough — the antivirus driver stays resident.
  3. Uninstall the FaceIT AC and Riot Vanguard anti-cheats if present — they block third-party software at the kernel level.
    • FaceIT is the CS2 anti-cheat, Vanguard is the Valorant one. If you don't play those games, they are safe to remove.
After removing an antivirus, restart the PC — some of its services only unload after a reboot.
A full walkthrough covering every case: How to turn off Windows Defender in Windows 11 and 10: fully or for one folder
Fully disable Windows Defender The #1 cause of “it won't launch”. Disable it for real: manually first, then remove it from startup, reboot, and finish it off with Defender Control.
  1. Step 1. Turn protection off by hand. Open Windows Security → Virus & threat protection → Manage settings and switch every toggle off:
    • Real-time protection — Off.
    • Cloud-delivered protection — Off.
    • Automatic sample submission — Off.
    • Tamper Protection — Off. Turn this one off first, otherwise the others switch themselves back on.
  2. Step 2. Disable reputation-based protection. In Windows Security → App & browser control → Reputation-based protection → Settings, turn everything off (SmartScreen, potentially-unwanted-app blocking).
  3. Step 3. Remove Defender from startup. Open Task Manager (Ctrl+Shift+Esc) → Startup apps tab, find Windows Security notification icon and click Disable.
  4. Step 4. Restart your computer. This is mandatory — some Defender services only unload after a reboot.
  5. Step 5. Finish with Defender Control. Download Defender Control (archive password: r1xon), run it as administrator and click Disable Windows Defender — the tile turns red.
    • If your antivirus deletes the utility itself, protection is still active — go back to step 1. The file ships zipped on purpose so Defender can't wipe it before it's disabled.
Don't skip steps 3–4. “I turned the toggles off but it didn't help” almost always means Defender came back after restart because it was left in startup.

Disable Core Isolation Memory Integrity blocks the driver from loading. Takes a minute to switch off.
  1. Open Windows Security → Device security → Core isolation details.
  2. Turn off Memory Integrity and restart the PC.
A full walkthrough covering every case: Core Isolation in Windows 11 and 10: what it is and how to turn it off
  1. Turn Windows Defender off completely, real-time protection included. The easiest way is the DControl utility.
  2. Turn Core Isolation off (Memory Integrity).
  3. Turn Reputation-based protection off — otherwise it blocks unfamiliar programs from starting.
  4. Uninstall third-party antiviruses — Kaspersky, Avast, 360, ESET, McAfee and others. Uninstall, not pause: they turn back on after a reboot.
  5. If Windows turns real-time protection back on after a reboot, download the loader into a separate folder and add only that folder to Defender exclusions — or run DControl before every gaming session.
  6. Do not turn on Windows test mode (testsigning): with it the loader blocks the key. If you turned it on for other software, run bcdedit /set testsigning off in an administrator command prompt and reboot the PC.

Launch

0 of 7 steps
  1. Download the loader from tndr-panel.online/loader/tundra_radar.exe — only after preparing Windows, otherwise the file is deleted mid-download.
  2. Right-click the loader file and choose “Run as administrator”.
    If you use a spoofer, start it only after the radar: first the radar on your real hardware, then the spoofer. If the spoofer goes first, the key binds to the spoofed hardware.
  3. At the top of the loader pick the server: RU for Russia and neighbouring countries, EU for Ukraine, Europe and everywhere else. Keep any VPN off: the radar does not need one, and together with the RU server it breaks the connection.
  4. Enter the activation key. If typing does not work, copy the key and paste it with Ctrl + V.
  5. Wait for the “Connected” or “Waiting for game” status. The loader window closes by itself and the radar link opens in your browser — that is intended.
  6. Start DayZ through Steam and join a server. The map is picked automatically: Chernarus+, Livonia, Sakhal or Namalsk.
  7. As soon as your character spawns, players, zombies, vehicles and loot appear on the map. Keep the radar tab open for the whole session.

First setup

Hotkeys work while the radar tab in the browser is active, not the DayZ window.

  1. F1 — settings: toggling categories, marker colors and sizes, distance number size, profile export and import, RU / EN language.
  2. F2 — player list: name search, sorting by distance, friends on top, a counter of players, zombies and cars.
  3. F — camera follow for the chosen player.
  4. The 2D / 3D switch sits in the top left corner. The 3D map is still in beta.
  5. Filters are split into the Players, Vehicles, Loot, POI, View, Style and More tabs. On a phone keep only the loot categories you need so the map is not overloaded.

Problems & fixes

8
The loader disappears right after the download
Windows Defender or an antivirus deleted it. Turn real-time protection off completely (DControl is the easiest way) and uninstall third-party antiviruses, then download the loader again. Better download it into a separate folder and add only that folder to Defender exclusions, not the whole Downloads folder.
The radar map is empty
In the main menu, in the server queue and on the loading screen the map is always empty — markers appear once your character is on the server. If you are in the game and there are no markers, refresh the radar tab (F5). If that does not help, close DayZ, run the loader as administrator again, wait for “Waiting for game” and only then start the game.
The radar shows the wrong map
The map is picked automatically by server: Chernarus+, Livonia, Sakhal and Namalsk. If the previous map stays after switching servers, refresh the radar tab (F5).
The key cannot be typed into the loader window
Copy the key to the clipboard and paste it into the field with Ctrl + V.
The loader crashes right after loading
A third-party antivirus or another game's anti-cheat is still installed. Remove the antivirus with its vendor's removal tool, and Riot Vanguard and FACEIT AC through “Add or remove programs”. Then reboot the PC and start the loader again.
The radar cannot connect to the server
Check the server at the top of the loader: RU from Russia and neighbouring countries, EU from Ukraine, Europe and other countries. Turn the VPN off if it is on, and start the loader again as administrator.
The key was activated while a spoofer was running
The key bound to the spoofed hardware. Reboot the PC so the temporary spoof resets, and start the radar without the spoofer: the loader shows a binding error and sends the developer a reset request. Then write to support that the key bound to the spoofer and ask to move the binding to your real hardware. From then on, start the radar first and the spoofer after it.
The radar page says “Key expired” although the term is not over
Go by the loader, not by the label in the browser: it can be wrong. If the loader starts and the map works, the key is valid — keep playing.

FAQ

8
Where do I get the key after payment?
The key arrives right after payment — it appears on the order page and lands in your email, and if Telegram is linked, our bot sends a copy too. If there is no key, message support with your order number.
Can I use one key on two PCs?
No: one key is one PC, and it binds to the hardware on the first launch. To move the key to a new PC or after a hardware change, start the loader with this key on the new computer: it shows an error and sends the developer a binding reset request. Then write to support and explain why you are moving the key. A move to a completely different PC on a different IP looks like key sharing, and such a reset may be refused.
Does the key time only run while I play?
No. The term runs continuously from the moment the key is activated, not only while you play: a 24-hour key ends 24 hours after activation, even if the PC is off. The developer counts activation and expiry times in UTC — Moscow time is 3 hours ahead.
Do I need a VPN?
No. Pick the server for your region at the top of the loader: RU for Russia and neighbouring countries, EU for Ukraine, Europe and everywhere else. Keep the VPN off: together with the RU server it breaks the connection.
How do I open the radar on a phone or a second monitor?
Copy the radar link from the browser address bar and open it on a phone or tablet. For a second monitor just move the browser window there. The interface is adaptive: on a touch screen the map is moved and zoomed with gestures.
Does the game need a particular window mode?
No. The radar draws nothing over the game — the map lives in the browser, so DayZ can run in any window mode, fullscreen included.
Is the radar visible on a stream?
Only if the map tab itself gets into the broadcast. Keep it out of streams and recordings — the radar does not change the game screen.
What if the product page says “On update”?
Do not run the radar until the status is cleared. The developer ships an update after game patches, and the status on the product page changes with it.

Still stuck?

Run R1XON Checker first — it pinpoints most launch problems in 30 seconds. If it still fails, attach the checker report to your support ticket and we’ll sort it out fast.
