REDLINE: Idle Front

"REDLINE: Idle Front" is a minimalist defense game where you build a line of high-tech turrets and hold your ground against endless waves of enemies. Machine guns, shotguns, snipers, rocket launchers, and lasers—each weapon has its own character and role in the defense. The turrets fire on their own, but you won’t last long without constantly upgrading them; a boss appears every five waves, and by that point, your weapons need to be top-notch. The base’s health is displayed on the right side of the screen, and if it runs out, you can watch an ad to restart the current wave or start over. After completing twenty waves, a slot for a second turret unlocks.

How to play?

Unlock the first turret and face the enemies—the weapon fires automatically. You earn money for every enemy killed; spend it on upgrading damage, firepower, and base health, and don’t forget to repair your base. To upgrade a specific turret, tap it and choose between damage, firepower, and critical hit chance. Once you’ve saved up enough, buy a new, more powerful turret and replace the old one. The further you advance, the stronger the enemies become. Don’t let your upgrades fall behind the increasing pressure, and try to approach each boss with the most upgraded arsenal possible.
