Last Radius Support

Getting started

Which devices can play?

iPhone with iOS 18 or later, from the App Store. The game plays in landscape and has dedicated layouts for iPhone Duo. The Android version (Android 9 or later, with Galaxy Z Fold layouts) is in closed testing on Google Play now, with the public release coming in the next few weeks.

Can I help test the Android version?

We are running a closed test on Google Play. Ask in our Discord if you would like to join.

Is it free?

Yes. Last Radius is free to download and play, with no ads. Optional purchases are available but never required to progress.

Do I need an account?

No. You can play without signing in. Signing in with Apple or Google is optional; on Android it is how your progress is backed up.

Where do I learn the controls?

Boot Camp runs on your first launch, and the full How to Play manual is on this site.

Progress and accounts

Where is my progress saved?

On your device, and backed up for you. On iPhone your Vault, Armory unlocks, Garage levels and records follow you through your own iCloud. On Android, open your Commander profile and sign in with Apple or Google to keep a cloud save.

I got a new phone and my progress is gone.

On iPhone, sign in to the same Apple ID with iCloud turned on and open the game; your progress comes back from iCloud. On Android, sign in from your Commander profile with the same Apple or Google account you used before. Still missing? Email us.

Does progress carry between iPhone and Android?

Not at the moment. iPhone progress lives in iCloud and Android progress in its own cloud save, so each platform keeps its own commander. Purchases stay with the store they were made in.

How do I delete my account?

In the game, open your Commander profile: Delete commander & all progress on iPhone, or Delete account & cloud data on Android. Or email support@kablooiegames.com and we delete your account and all of its data within 30 days. Full steps are on the account deletion page.

Gameplay

My laser stopped firing.

It overheated. At 100% heat the laser locks and vents; the Laser hex counts the vent down. Keep it between 60% and 99% for overcharged fire without the lockout.

Why did my parry miss?

Tap the shield on the side the hull is coming from, as its ring closes. Parry catches hulls within about 45° of the tap, and a miss locks it for 0.6 seconds. Bulwarks, Carriers, Hammers, Heralds, Scramblers, bosses, rams, decoys and latched Leeches cannot be parried at all.

My shots do nothing to some hulls.

Some hulls carry counter-traits against particular weapons, and the hit shows as blocked. Switch weapons: missiles, pulse, Tesla or a parry where it is allowed.

How do I unlock the Tesla Coil and the other ordnance?

With vault salvage in the Armory. Tesla Coil is first at 250. After unlocking, open Build during a wave to deploy it. Every Armory card has a free Test button.

What is the difference between run salvage and the Vault?

Run salvage is spent during the run you earned it in. Vault salvage is banked for good and pays for Armory unlocks, Garage levels and Core rank. Part of any unspent run salvage is banked when the run ends.

What is Overclock?

Clear wave 30 in Endless Defense to unlock it. Each Overclock level starts the threat curve six waves deeper and raises the rewards.

Why does the game feel harder every wave?

It is meant to. Every wave escalates, and the Threat Director sends counters to how you play. Mix your weapons and read the banners.

Purchases

What can I buy?

Matrix Gems (500 or 1,200) and a one-time Commander’s Starter Pack. Gems buy Booster Blueprints, planet skins, Insurance Keys and supply crates in the Vault Terminal. No subscriptions and no loot boxes.

My purchase did not arrive.

Close and reopen the game while online. If it still is not there, email us with the date and the store receipt and we will sort it out.

How do refunds work?

Refunds are handled by the store you bought from: reportaproblem.apple.com for the App Store, or your order history in Google Play.

Do purchases carry between iPhone and Android?

No. A purchase belongs to the store account it was made with.

Troubleshooting

The game crashed or froze.

Make sure you have the latest version from the store, then restart the game. If it happens again, email us your device, OS version and the wave you were on.

There is no sound.

Check that your phone is not on silent and the volume is up, then open the pause menu: SFX and COMM FEED (music) each have their own switch.

Can I play with one hand?

Turn on One-Thumb Assist in the pause menu. It fires your missiles as soon as they are ready and triggers the pulse when three or more hulls crowd the shield, so your thumb can stay on the laser and the parry.

The layout looks wrong on my foldable.

Rotate to landscape, or fold and unfold once so the game picks up the new posture. If it stays wrong, send us a screenshot.

I found a bug or have an idea.

Post it in our Discord or email support@kablooiegames.com. Screenshots and the wave number help a lot.
