Nebulas (v0.6.19)

Star Vortex · published 23 Feb 2026, 21:56 UTC · build 22062603

All newsPlayers around this dateRead on Steam

This update is here a little earlier than planned. Once the performance gains started stacking up and the visual upgrades came together, it felt wrong to delay it though.

Nebulas

They’ve been on the roadmap for a long time and you'll now occasionally encounter them while exploring. They’re not common, but when you do find one, visibility drops hard hopefully giving a very different feel to combat. It may be tweaked in future updates but I want to see what you guys think first.

Bloom + Gateways

I’ve upgraded the bloom system with proper tonemapping. Glows now keep their colour instead of blowing out into flat white. At the same time, Gateways have been reworked with proper portal shaders and new entry animations.

This ended up being a much bigger visual improvement than expected. In hindsight, I should have done it sooner but it's here now!

Brightness

The overall game brightness has been increased slightly. If you dislike this there's now a Brightness slider in the settings. Background Darkness is still adjustable separately under Accessibility.

To keep ships readable against brighter environments, they now have a subtle black shadow.

Performance

This update includes a major performance pass across the entire game.

Large fights with heavy projectile and drone counts should feel noticeably smoother. Drone weapon pools are now preloaded before combat, so you won’t get that initial stutter when a swarm fires for the first time.

A lot of invisible per-frame allocations have been removed from targeting, clean-up, and patrol systems. That means fewer garbage collection spikes and fewer random hitches.

Steam Deck performance in particular should now feel much more stable.

Sector 4 - Phase 1 Progress

Work on Sector 4 continues behind the scenes. You'll start seeing new Species-XI enemies appearing in the next update, and boss development for this phase is about to begin.

Full details are listed below. Enjoy!
