You can download the launcher / patcher from the following link. This is the easiest and most efficient way to get into the game and keep it patched. (As of 1/26/2021 6PM PST we have false detections with this installer. It was created with game launcher creator if you want to look into it.)
If you prefer not to trust the launcher you can simply install the game manually using the .7z file. This method will result in no detections but you will have to check in when there is a new patch. Instructions are included.
Manual patch is needed as of 1/26/2021 6PM PST (the manual patch is working as of 5/13/2021)
