Idle Defense: Cosmic TD

THE IDEA

How it plays

Keep a space station alive through incoming waves while its weapons fire automatically. Spend enemy drops on upgrades, specialise the core and carry long-term gains into future runs.

1. Choose attack, defence and utility upgrades as waves approach.
2. Tap enemies for extra damage and upgrade the station between waves.
