Step-by-step launch for Tundra Radar. The map opens in a browser, so there is no in-game menu — every setting lives on the radar page. Most of the work is system preparation: with Windows protection on and Secure Boot enabled the loader cannot read game data.
Requirements
- Windows 10 or 11 (x64), any release build
- The game from the Arena Breakout launcher or from Steam
- Access to BIOS/UEFI — Secure Boot has to be turned off
- A second screen, phone or tablet to keep the map open
- Administrator rights on the computer
System requirements
Preparation
Disable Windows protection and prepare the system BEFORE downloading the loader — otherwise the antivirus removes the file right after the download.
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.
-
Open Settings → Apps → Installed apps (or Control Panel → Programs and Features).
-
Uninstall any third-party antivirus (Kaspersky, Avast, AVG, ESET, 360, Malwarebytes, etc.). Pausing or disabling is not enough — the antivirus driver stays resident.
-
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.
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.
-
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.
-
Step 2. Disable reputation-based protection. In Windows Security → App & browser control → Reputation-based protection → Settings, turn everything off (SmartScreen, potentially-unwanted-app blocking).
-
Step 3. Remove Defender from startup. Open Task Manager (Ctrl+Shift+Esc) → Startup apps tab, find Windows Security notification icon and click Disable.
-
Step 4. Restart your computer. This is mandatory — some Defender services only unload after a reboot.
-
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.
-
Open Windows Security → Device security → Core isolation details.
-
Turn off Memory Integrity and restart the PC.
Disable Secure Boot Secure Boot stops the loader from starting. Check the status first, then disable it in BIOS if needed.
-
Check the status: press Win+R, type msinfo32, and in System Summary find Secure Boot State. If it reads Off or Unsupported — you're set, skip the rest.
-
If it's On — enter BIOS/UEFI (tap Del, F2 or F10 while the PC boots — depends on the motherboard).
-
Find Boot or Security → Secure Boot and set it to Disabled. Save (usually F10) and reboot.
- If Secure Boot is greyed out, set a Supervisor Password under Security first — that unlocks the option. You can remove the password afterwards.
Sync Windows time A wrong system clock breaks key authorization against the license server.
-
Open Settings → Time & language → Date & time, enable Set time automatically and click Sync now.
-
Turn off Reputation-based protection: `Settings` → `Privacy and security` → `Windows Security` → `App and browser control` → `Reputation-based protection settings` — switch everything off
-
Disable the vulnerable driver blocklist. Press `Win + R`, type `regedit`, open `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CI\Config` and set `VulnerableDriverBlocklistEnable` to `0`. If the value is missing, create it as a DWORD (32-bit)
-
Restart the computer after all the changes. Windows often re-enables real-time protection after a reboot — check it again and turn it off if needed
-
Only now download the loader — download Tundra Radar — and put it in a separate folder, for example `C:\Tundra\`
Launch
-
Run tundra_radar.exe as administrator
-
Enter the activation key from the email or from the bot and confirm
-
Wait for the status line to read Connected or Waiting for game. Do not close the loader window — it closes on its own and opens the map link in the browser
-
Start the game and enter a raid as usual: pick the map and mode, wait for the location to load
-
Once you are in the raid, players, bots and loot appear on the map by themselves. In the main menu and during loading the map is empty — that is normal
-
Keep the map tab open for the whole raid. Nothing needs restarting for the next raid — the map switches by itself
-
Tip: open the radar link on a phone or a second monitor. That keeps the map out of your stream capture and always within reach
Problems & fixes
The map is empty, no players and no loot
Make sure you are already in a raid: in the main menu, the hideout and the loading screen the map is empty by design. If a raid is empty too, the loader is not reading the game: usually Memory Integrity (Core Isolation) is on, or Windows restored real-time protection after a reboot. Turn both off, restart and run the loader again.
The antivirus deleted the loader right after the download
It is a false positive, normal for this kind of software. The order matters: first fully disable Defender and remove third-party antivirus software (Kaspersky, Avast, 360 and similar), and only then download the file. If the file is already gone, restore it from quarantine or download it again after protection is off, and add the loader folder to exclusions.
The loader window closed by itself — is that an error?
No, that is the intended behaviour. After a successful connection the loader closes and opens the map link in your default browser. If the browser did not open, the link is still valid — take it from the browser history or run the loader again and copy the address from its window.
The key is rejected
Copy the whole key from the email or the bot with no trailing spaces, and do not type it by hand: `0` and `O`, `1` and `I` are easy to confuse. Then check the system time — activation fails when it drifts from real time: `Win + R` → `timedate.cpl` → `Internet Time` → `Change settings` → `Update now`, or `w32tm /resync` in an administrator command prompt.
The loader does not start or closes immediately with an error
Run it as administrator — without that it cannot reach game data. Then check that Secure Boot is off in BIOS/UEFI and that `VulnerableDriverBlocklistEnable` is set to `0` in the registry. The registry change needs a reboot, otherwise it does not take effect.
Positions on the map do not update or lag behind
The map tab has to stay open for the whole raid: a minimised or browser-discarded tab stops receiving updates. On a phone, prevent the system from sleeping the tab and do not keep the screen off for long. If only you lag behind, check the connection — updates are tuned for low traffic, but the map freezes when the link drops.
The wrong map was detected
Detection follows the loaded location, so a map change is picked up when you enter a new raid. If the old map stayed, refresh the radar page (`F5`) while already in the raid. On TV Station also check the selected floor — that map is split into levels.
Too much loot on the map, nothing is readable
Raise the price filter — it starts at 35,000 but can be set with the slider or typed in manually. Turn on strict mode to keep known items only, without containers and junk. If it is the whole overlay rather than the loot, start from the Minimal preset and add what you need on top.
Advanced setup — only if it still won’t launch
Use a VPN for download and activation CIS ISPs often block the activation servers. A VPN is needed while downloading the loader, activating the key and injecting — you can turn it off before joining a match.
-
Use a full VPN (an app that routes all traffic), not a browser proxy, VLESS or extension — half the support tickets come from exactly this.
-
Turn the VPN on before downloading the loader and activating the key. If something won't load, switch country (Europe or the US usually work).
-
After a successful inject you can turn the VPN off before the match to avoid extra ping.
A VPN fixes most endless-loading and "key won't activate" problems.
FAQ
Where do I get the key after payment?
The key arrives instantly after payment — it appears on the order page and lands in your email, and if Telegram is linked to your account, our bot sends a copy too. This guide opens from there as well.
Which key opens the menu in game?
None. This is a web radar: nothing is drawn over the game and every setting lives on the map page in the browser. That is why it does not conflict with overlays and stays out of screen capture when the map is open on a phone or a second monitor.
Can I open the map on a phone?
Yes, there is a dedicated mobile layout — portrait and landscape, with adaptive panels. Open the same link the loader gave you on your phone. Position updates are tuned for low traffic, so mobile internet is enough.
Do I need to restart the loader between raids?
No. One launch covers the whole session: the map clears when you leave a raid and fills up again on the next one, switching to the right location by itself. A restart is only needed after rebooting the computer or closing the game entirely.
Are settings kept between launches?
Yes. Your own layout is saved as a preset, next to the ready-made Minimal, Medium and Full. Settings move between devices with Export / Import — handy when the computer and the phone use different layouts. Reset all restores the factory look.
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.
