REDLINE: Idle Front

REDLINE: Idle Front is a minimalist base defense game about building a firing line of high-tech turrets against endless enemy waves. Machine guns, shotguns, sniper rifles, rocket launchers, and lasers each fill a different role on the field. Your guns fire automatically, but heavy upgrades are the only way to survive. Bosses show up every five waves, and by then your loadout needs real stopping power. Base health appears on the right side of the screen. If it hits zero, you can watch an ad to retry the current wave or restart from the beginning.

How to play?

Buy your first turret and let it fire on its own while you rack up cash from each kill. Spend that money on turret damage, fire rate, and base health. Repair the base whenever it takes a hit. Tap an individual turret to upgrade its damage, fire rate, or critical hit chance. After wave 20, you unlock a second turret slot. Save enough cash to swap old guns out for stronger ones, then stay ahead of the rising enemy strength before the next boss arrives.
