Or check your Steam compatibility data folder if using Proton.
Steam Cloud
If Steam Cloud is enabled, saves may also sync to:
Steam/userdata/<your-id>/1649950/remote/
File types
.nt files are your game saves. Each game session gets a UUID (e.g. ae80f3d2-...). Within a session:
uuid.nt — the initial save uuid-1.nt, uuid-2.nt, etc. — numbered manual saves (higher = more recent) uuid-autosave.nt — the game's autosave .nta files — autosave snapshots (latest state of each session)
To find your most recent save, look for the .nt file with the highest number suffix and the most recent modification date.
Viewing save files manually
News Tower .nt saves have a 171-byte binary header, then gzip-compressed JSON, then a 16-byte MD5 checksum at the end. To peek inside a save yourself:
macOS / Linux
tail -c +172 your-save.nt | head -c -16 | gunzip | python3 -m json.tool | less
Windows
Install 7-Zip (free), then right-click the .nt file and choose 7-Zip → Open Archive. You'll see the gzip-compressed JSON inside — extract it to view the save data in any text editor.
Note: 7-Zip will skip the 171-byte header automatically when decompressing the gzip stream.
Python
import zlib, json
with open("your-save.nt", "rb") as f:
raw = f.read()
data = json.loads(zlib.decompress(raw[171:-16], 31))
print(json.dumps(data, indent=2))
