Hello brave astronauts,
The cosmos is calling, and your mission starts now! The Cosmic Carnage Steam Playtest is officially live. 🚀
The galaxy is vast and fraught with danger, and we need your expertise to clear out the final bugs, balance the weaponry, and ensure smooth hyperspace travel before our official launch. This is your exclusive chance to get an early look at a late-stage build of the entire game!

Initial Duration: 1 Week
Potential Extension: The playtest may be extended for an additional week (total of 2 weeks), depending on the feedback and anomalies we uncover. We will transmit updates via Steam News posts if an extension is required.

This is a comprehensive test of the game's full content. We're looking for feedback on:
Game breaking bugs: Issues that prevent you from completing a level or the entire game.
