Build your deck using cards, ships, items and crew! Explore a generated galaxy roguelike style. Fight gruesome battles against the medley of space scum!
CosmoPirates takes the card battling, deck building genre to the final frontier of cartoonish comedy in the endless, colorful space! Explore the galaxy, chose your battles, grow your forces and build your ultimate deck to take on the dreaded CosmoPirates overlord... and take their place!

With each run, the game presents you with a new, procedurally-generated galaxy full of bounty, danger, oddball characters, and high adventure. You will explore it freely taking on the challenges and quests in the order you think is best. Be cautious or daring - your crew looks up to you for the winning strategy!

Gadgets, weapons, gambits, and strategems - each card can change the tide of battle. Find them while exploring, buy them, win them in combat, and make sure you figure out the best combos and synergies. Will you lick a battery to gain extra power, or read comic books for extra action points?

In CosmoPirates your destiny takes you on a quest to rise to power and put an end to the great pirate overlord's reign of terror. The overlord must die! Die! DIE! As soon as they do, you take their place, effectively ending your run. The next time you play, you'll be up against your previous character, with all the power they acquired in the previous run.
This game was crafted by two passionate developers. We invite you to share your thoughts, ideas, and any issues you encounter. Your feedback is invaluable to us, and we are dedicated to making CosmoPirates the best it can possibly be!
