Frequently Asked Questions – Core Keeper (v1.3.0.6)
Is Core Keeper completely free?
This page offers a free pre-installed download of Core Keeper v1.3.0.6 at 1.2 GB. The game itself is a paid title on Steam, so if you enjoy it, buying a copy supports the developers and gets you automatic updates.
How do I install Core Keeper?
Download the 1.2 GB archive, extract it into a folder excluded from your antivirus/Defender, install the apps from Redist or _CommonRedist, then run the game as administrator. A detailed Installation Guide.txt is included inside the game files.
Does multiplayer work in this build?
Yes. The build ships with the online fix, so co-op works over the internet with friends running the same version. Join through the in-game lobby or Game ID. Joining via IP has been reported as unreliable, so use the Game ID method if IP fails.
Can I play Core Keeper offline?
Yes. Single-player works fully offline with no internet connection required. Only multiplayer and co-op need a connection.
Where are my save files stored?
Saves are located at C:\Users\[YourUsername]\AppData\LocalLow\Pugstorm\Core Keeper\Saves. If the folder does not exist, launch the game once and create a world to generate it.
Why does my antivirus flag OnlineFix64.dll?
Online fix files are commonly flagged by antivirus software because of how they modify game networking. This is expected for this type of file. Scan the archive yourself and decide whether that risk is acceptable to you.
