What is Selaco?
Selaco is a sci-fi first-person shooter from Altered Orbit Studios. Security chief Dawn Collins investigates the past of a huge space station where survivors found refuge after the fall of Earth. During her investigation, armed attackers storm the station.
The game combines fast-paced gunfights with a connected campaign world. Rooms can be searched, paths lead back to previously visited areas, and many objects react to gunfire.

Gameplay
In the campaign, Dawn Collins explores offices, industrial facilities, service corridors and other parts of the space station. Combat alternates with searching for hidden rooms, resources and access points. The levels are interconnected and rely on orientation rather than a simple sequence of closed arenas.
Movement and positioning are important: Dawn can attack quickly from cover and slide through firefights. Environmental objects, furniture and glass panes are damaged or destroyed by gunfire.

Enemies and combat tactics
The enemies work in groups, use cover and try to flank Dawn or pin her down with sustained fire. Their radio messages and calls give hints about the situation in combat.
The Machines of War adds new enemy types such as Skirmishers, Tanks and Incinerators. The studio also announces a fundamentally reworked AI system with patrols and a new rally system. This is meant to let Dawn initiate more fights herself.

The Machines of War: The second chapter
The Machines of War releases on November 13, 2026, free for the PC version. 19 new campaign maps are set to extend the story by about six to eight hours. Dawn temporarily gets support from a companion figure while a powerful machine hunts her through new areas.
At the same time, Altered Orbit Studios is reworking the first chapter with adjusted lighting, new details and changed gameplay situations. The expansion therefore not only adds to the story but also changes existing content.

Progress and save games
New weapon upgrades and equipment can be managed in safe rooms, among other things. With the second chapter, missed regular Weapon Kits are also meant to become available retroactively there. Additional mutators enable alternative rules and encounters.
The update from November 13, 2026 is not compatible with previous save games. Players who have already finished the first campaign can jump straight into the second chapter. For ongoing runs, the studio announces an older version via the Steam beta branch CHAPTER1. Unlocked Weapon Kits are retained in the process.
