Guides
Get better at Cosmic Starship
Strategy, systems and secrets, written from the game’s own numbers.
New players should start with How to play and the beginner’s guide. The guides below go deeper.
Where to start
Each guide answers one question and is written from the numbers the game itself uses, so the stats, prices and cooldowns match what you see in the hangar. If you have just finished First Light, read the best ships for beginners before you spend your first credits, then squad command: your six squads do most of the fighting, and giving them the right duty wins more battles than any upgrade.
Stuck on a mission? The boss guide covers all nine bosses phase by phase, and difficulty and Threat levels explains what each of the six difficulty steps changes. When you start collecting gear, mods, catalysts and crafting and doctrines and play styles show how to turn drops into a build. The guides are updated with the game; the patch notes list what changed.
