Tiamat X casts you as a pilot defending your homeworld after the Choazid Empire establishes a fortified base and turns captured subterranean lifeforms into biomechs. Your craft is the X-class Tiamat dragonship, one of the few prototypes left. The game frames its conflict as a race to stop the invaders before they begin converting your people, giving its arcade-style shooting a clear, urgent premise.
Combat centers on dodging enemy fire and blasting through six levels. Upgrade caches collected during a mission supply the fighter’s immense firepower, so survival and building up your ship go hand in hand. Auto fire can remove the need to press a fire button, while quick fire lets you hold a button or key instead of repeatedly tapping it. A color-blind filter is also listed among the accessibility features. The design takes its cues from side-scrolling shooters of yesteryear, backed by an original music score and a deliberately arcade-like spirit.
Tiamat X is listed as single-player, with Steam achievements and leaderboards alongside its action. Its combination of scrolling combat, upgrade pickups, and optional firing controls makes the classic arcade inspiration concrete without losing sight of the homeworld-defense story.
