Welcome to the ootss wiki! Also see Maps, Stalker 2, Supraworld, SupraTools, Subnautica, and Sokoban wikis.

The map features all 105 levels from Stage 2 Demo (Jun 19 2026).

Uses Sysinternals Process Monitor (filtered by CreateFile) to get level names, uses 16k virtual display to capture the map.

I don't know any cheats or console commands to load the levels. The names are just to identify the levels properly. The general idea for the map is to use the game naming convention. Wasn't worth it, names are kind of random and don match the order.

I used my own numbering back then and it was way off, so I thought I'd rather use map names from the game engine.

Solutions

There are a few solutions in Autohotkey rle format, see file here: https://github.com/joric/ootss/tree/main/data/solutions.txt

  • Install Autohotkey. Run solutionsPlayer.ahk. Press Ctrl+E to select level to solve, Alt+E to solve and select next level, ESC to stop.
  • To record a solution, use AHK2-Macro-Recorder, F2 to record, F3 to open, paste to raw, run encode_raw.py to convert.

You can also try to type those keys manually, e.g. d2xa4xa6w means ddxaaaaxaaaaaaw, but it's a lot to type.

Gallery

Added image gallery (swiper lib). Now it's easier to find map location by image. You click on the image in the marker popup to open gallery, select map image in the gallery, click on it and it brings you to location.

Development

There's no tools for that game just yet, the engine is totally custom, let alone custom compiler, so it's all human labour.

Level Names

Launch game, launch Sysinternals Process Monitor. Add filters Process Name - is - sinking_star.exe, Operation - is - CreateFile, Path - contains - levels. Load the level in the game, you will see all the file names the game reads.

Map Capture

Download Universal Virtual Display Driver. Unpack to C:\IddSampleDriver. Edit option.txt, add 16384, 9216, 30. Do not install .inf from explorer, use Device Manager - Action - Add legacy hardware - Display Drivers - Have disk. Set virtual display resolution to 16384x9216, run the game, open map, press Win+Shift+Right to move the game to Virtual Display, press PrnScr, paste image into editor. I tried to capture at 8192x8192 but apparently the game doesn't like square geometry (cuts the map).

The overhead map goes into minimal LOD (even in high quality settings). It's barely noticeable in low resolution but it's very obvious in high-res. I can't stitch local maps (Q) because of camera distortion. I know the meshes on the image are broken, that's because the map draws in lowest LOD, I can't change it in settings and I don't have other options for now.

Regions

Used the same tech as in Subnautica 2 (raster map traced with rasterio and cleaned up with mapshaper. Regions appear to be slightly off in the demo, e.g. heroes2_10 level does not belong to any region boundaries.

Grid System

There's a grid system, working on it. On the 1920x1080 screenshot the grid size is about 10 pixels with map center at 860,740.

Looks like cell 069, 104 is way out of the demo map if it's even coordinates. Or my coordinate system is wrong.
