About This Game

Earth has already fallen.

Alien forces crash-landed across the planet after a catastrophic asteroid event, overrunning every nation in the chaos that followed. Cities burned, armies collapsed, and humanity was pushed to extinction’s edge.

Your base is all that remains.

Planetfall: Endless Wave is an idle incremental base-defence game inspired by classic RTS visuals and the escalating chaos of games like Risk of Rain 2. Each wave grows stronger, faster, and deadlier — and survival depends entirely on how you evolve your base.

Upgrade your defences, deploy troops, and watch your systems fight back as the battlefield becomes a relentless war of attrition.

DEFEND. UPGRADE. SURVIVE.

• Face endless waves of enemies that scale in strength, numbers, and aggression

• Upgrade your base to increase:

  • Turret damage and critical damage

  • Base and wall health

  • Turret radius and coverage

• Spawn and command troops to support your automated defences

• Manage resources earned over time to optimise long-term survival

• Watch the battle unfold even while idle — progression never stops

OLD-SCHOOL LOOK, MODERN IDLE DESIGN

Featuring a deliberately retro RTS aesthetic, Longest Battle blends hands-off incremental progression with strategic decision-making. Your choices matter — build wide, build strong, or specialise your defences to survive just one more wave.

There is no final victory.

Only how long you last.
