About this game
The time has come for a new era of space exploration. We can detect and use warp portals to travel to other galaxies. But it allowed other space dwellers to detect us...
...and not all contacts are going to be peaceful. Especially, if you are a member of Cosmo Riders guild who pays bounty for capturing outposts and disassembling ships.
Advance
Travel through galaxies and solar systems during Expedition where each stage may have different conditions and events(from destructible asteroids to flying comets).
Research
Research new weapons, modules and modifications between Expeditions.
Improve
Upgrade Ship during Expedition: install researched weapons, modules, modifications. Change basic aspects (attributes).
Deal
Complete Contracts to unlock new Research Tiers.
Conquer
Defeat enemy waves, extract cargo and components and jump into warp-portal to next stage. Enemies may also use different weapons and modules, but they can be shot-off during fight (node-based destruction).
FAQ
Run duration: one expedition takes near 1 hour, with ~20 minutes per each phase. Also progress is saved each ~1-3 minutes, the expedition can be postponed almost any time.
Total playtime: 18 Galaxies with unique conditions and 6 difficulties (configured per galaxy). It will take at least 20 hours to beat all galaxies at one difficulty level. All progress can be reset after completing all galaxies (statistics is kept).
Meta-progression / Boosters: researched items appear during run(Expedition). Researched items can be crafted before Expedition start. Permanent bonus Attribute point is obtained after completing Galaxy.
Ship builds (gameplay styles): 3 archetypes can be defined for now: ranger-with-focus-on-weapons, ranger-with-focus-on-modules and melee-hyper-boost-rammer. And ship modification system is flexible enough to combine different styles.
Randomness: it is possible to predefine ~50% of build before Expedition starts. Other 50% are choices done during Expedition.
