About This Game

The aliens don't stop. Neither should you.

Solar Defiance is a high-energy arcade space shooter built for players who thrive under pressure. Waves of aliens descend faster with every round, and the only thing standing between you and oblivion is your trigger finger — and how smart you spend your coins.

After every wave, choose your investment. Power-ups give you an immediate edge. Upgrades make you permanently stronger. With seven options to choose from and a boss battle triggering every five waves, no two runs feel the same.

The longer you survive, the more dangerous it gets. The more dangerous it gets, the stronger you become.

Features:

  • Endless arcade gameplay with escalating difficulty

  • Roguelike upgrade system — persistent upgrades and temporary power-ups

  • Boss fights every 5 waves against a giant space pirate warship

  • High score system — how far can you push it?

  • Full controller support including Steam Deck

  • Sessions from 2 to 10 minutes — easy to pick up, hard to put down
