The dreadnought KHARYBDIS broke through the picket line. Every run starts on the launchpad — hold off the boarding wave, fly the ascent corridor while your power plant spins up, then take the fight to the sector.
ADVENTURE chains ten boss-gated maps; you CHOOSE a refit after each sector and it bolts onto your hull for the rest of the run. Death resets everything. ENDLESS drops you into the classic infinite-wave arena.
