Cosmic Strike 2.0 is a free online 3D space shooter where you pilot a spaceship through three increasingly brutal levels, blasting enemy fleets and going head-to-head with powerful bosses that each require a completely different strategy to beat. No downloads, no installs — just pick a ship and start fighting.

Each of the three levels ends with a boss fight that changes how you play. You can't just spam the trigger and hope for the best — especially the final boss, who has a specific weak spot you need to identify and target. Between levels, spend your earned cash in the ship store. Different ships come with different damage outputs and firing styles, so experimenting with your loadout actually matters. Some ships fire rapid short bursts, others hit harder with slower shots — finding what suits your playstyle is half the fun.

If you're into free online space arcade games, 3D spaceship shooters, or single-player action games you can play on both desktop and Android, Cosmic Strike 2.0 delivers a solid challenge without wasting your time. It's a great pick for fans of classic arcade space combat who want boss fights with real mechanics rather than just bullet sponges.
