About this game
Launch your heavily armed Star-Fighter into devastating battles across the galaxy in an intense on-the-rails space shooter. Take the role of a skilled fighter pilot assigned to the Interstellar Battleship Alastrius, the only capital ship still fighting for the Republic following a sudden coup d'état. Your mission is simple; blast a path through numerous enemy strongholds, liberate the capital world Velora and restore the Republic. However the enemy forces are vast and they will throw every weapon they have in your path.
From lush green forests to vast deserts, explore bottomless icy glaciers and broken volcanic mining worlds. Plot a course through 16 different planets, space stations, nebulae and other hazardous locations as you guide the Battleship Alastrius back to its home world. With numerous different missions and storyline developments it will take many playthroughs to discover everything.
The Battleship Alastrius carries a diverse range of playable Star-Fighters from nimble, lightly armed ships to hulking goliaths. When a Star-Fighter is lost in combat its gone for the rest of the campaign so choose your fighters for each mission wisely. The game begins with three different Star-Fighters with a further seven that can be unlocked.
Each Star-Fighter is equipped with multiple Laser Cannons able to shred through enemies, even at long range. If more firepower is needed powerful homing Missiles can make short work of even the toughest targets and if that's not enough the Star-Fighters arsenal of Bombs can devastate everything in a vast area.
The devious Imperium have usurped almost the entire Republic military and will throw hordes of forces at you including drones, fighters, tanks, boats, turrets, mines and traps. Find your enemies weakpoints to destroy them efficiently and rack up impression mission high scores. Can you earn a Gold Medal in every Mission?
Saving the most insane superweapons to the end of every mission these hulking war machines will test your skills. Depending on your path a different boss may be poised to strike.
Familiarise yourself with the Star-Fighters controls and weapons systems by taking on the Training Simulator. You have been assigned a Dispatch Officer onboard the battleship Alastrius; Rahalla who is fully voice acted will be your loyal companion guiding your Star-Fighter through the Training Simulator. Rahalla will also guide you through all the campaign missions, sharing developments as the civil war unfolds.
The game contains 40 Steam Achievements if you are looking for a wide array of additional challenges. Achievements are also tracked independently within each of the games six Save Files so friends or family with access to your Steam Account can still go Achievement hunting themselves even if you have unlocked them already on Steam.
Alastrius offers full Keyboard-and-Mouse controls allowing you to shoot using the Mouse with pinpoint accuracy. If you prefer the Gamepad get ready for a classic Twin-Stick Shooter experience. Both control systems offer full rebinding options.
Alastrius features heavily stylized envrionments and vehicles with sharp lines and bold colours. The game is packed with atmospheric music and intense retro boss tracks.

Alastrius Title Refinement
Since the games launch in March 2026 this sci-fi rail shooter has been titled 'Alastrius' after the large space battleship that escorts the player throughout the game. The game name has now been extended to Alastrius: Star-Fighter The main reason for this is Alastrius is planned as a franchise with additional games set in the same universe but expanding into other genres of gameplay. A second game is planned for a 2027 release and by giving both games a unique subtitle it will easier to manage both projects going forward. Another reason for the addition of the subtitle has simply been to improve the games discoverability on Steam and to give more detail to anyone seeing the games name without further context. This 1.1.6 update has added the Star-Fighter subtitle to the games main menu and has also integrated the Demo label for the demo version of the game.Read full article on Community Announcements (mcmacleod86)Patch NotesOfficial
