Selaco's next chapter is set for November 13, and this is not a routine patch disguised as a major event. Developer Altered Orbit Studios says The Machines of War will add 19 campaign maps, approximately six to eight hours of story content and substantial changes to the existing game. The update is free for current owners. Players should also know about the drawback before launching the game again: older saves will not carry over into the new build.
Selaco is a first-person shooter that looks backwards without simply copying old games. It is built on GZDoom technology and draws clear inspiration from the tactical behaviour of F.E.A.R. enemies, the speed of classic Doom and the exploratory spaces of immersive shooters. The first chapter launched in early access in 2024, and the developers have spent more than two years building the second. The new release is a sizeable step toward a complete campaign rather than a seasonal detour.
What The Machines of War adds
The headline addition is Chapter 2 itself, a continuation of the campaign across 19 new areas. Altered Orbit estimates around six to eight hours of additional content, but actual playtime will depend on difficulty and exploration. The studio has also teased new weapons, more voiced characters and enemies built around the chapter's mechanical theme. Calling this a second game would go too far: it remains an update to the early-access Selaco package.
Just as important, Chapter 1 is being reworked. The developers have spoken about refreshed set pieces, improved lighting, new surprises and changes to level navigation. Someone who finished the opening campaign in 2024 may find familiar encounters behaving differently when they return. That explains part of the save-compatibility problem: substantial internal changes make preserving every old state much harder.
The enemy AI is being rewritten
Selaco earned attention for enemies that move together, use cover and try to push players out of easy defensive positions. The new update goes further with a major rewrite of decision-making and pathfinding. Altered Orbit has described improved patrol behaviour outside combat and systems that help enemies react more coherently when they lose sight of the player.
The appeal is straightforward. In a corridor shooter, difficulty is often achieved by increasing enemy health or damage. Better tactical enemies can make the same room interesting in several ways, even when the number of opponents stays the same. The danger is that smarter AI can become unfair if enemies appear to know the player's position without seeing them. The studio says it is also improving cues and navigation to make the action readable, not merely harder.
What happens to existing saves?
The developer says saves from the current build will not be compatible with The Machines of War. That is the detail players should check before spending an evening trying to finish a chapter they are halfway through. The update is expected to let players begin from Chapter 2 rather than force everyone through the reworked first chapter, but switching between incompatible versions is not as simple as copying a save file.
If you want to preserve a particular run for reference, make a backup of your existing save directory before updating. Whether you can actually load that backup later depends on having the corresponding older game build and its files, so it should not be treated as a guaranteed recovery method. The developers' launch notes will be the authoritative place for compatibility instructions.
Free update, not a paid expansion
Altered Orbit has repeatedly said Chapter 2 is included in the early-access price. That keeps the business model uncomplicated: buying the game now includes the ongoing campaign work rather than a separate chapter purchase. It also means the new content can revive interest in the existing Steam release without splitting the audience into incompatible ownership tiers.
The studio has not presented Selaco as a finished version 1.0 release. More work and later content are still part of the plan. It is better to judge November 13 as a substantial early-access milestone and ask whether the improved first chapter and new maps hold together than to pretend the full project is done.
Should new players start now or wait?
If you enjoy retro-inspired shooters and do not mind early-access rough edges, the current Selaco already offers a dense campaign. But with an incompatible-save update approaching, new players may prefer to start after November 13 so their first run uses the updated navigation and combat systems. Returning players have a reason to revisit the opening chapter, even if that means beginning again.
The strongest part of the announcement is not the number of maps. It is the willingness to rework the foundation while adding new content. That is risky for save files, but it may produce a better shooter in the long run.
