A downloadable game for Windows, macOS, and Linux

They Came From the Sea is an endless, wave based 2D shooter, where you are trapped on an isolated island battling everlasting hoards of eldritch horrors. Your own demise is the only guarantee here, thus you can only hope to survive just a little longer than last time. But hey, at least you'll have fun doing it!

Employ a combination of speed, relentless streams of bullets, and the occasional power up, in order to make it to the top of your personal leaderboards in this fast paced, fun, and addicting game! 

Note: Leaderboards are entirely local to your device. Online leaderboards may be added in future.

And, if you want a real challenge (or find the later waves to be a little too much), you can go into the custom game options, and tweak certain values, such as enemy move speeds and health. This allows for plenty of fun and unique challenges, as well as a way to tweak difficulty to fit your preferences.

Hey, this is a really nice run-and-gun endless shooter. I particularly like the monochrome graphics and creepy atmosphere it and the music give the game. The game hasn't got an incredible longevity (upgrades could be one avenue to extend this) but it's a fun one. Great job! 

Hey, thanks a lot for the feedback! I'll be sure to look into ways of improving the longevity of the game. Glad you enjoyed the game, and thanks for playing!
