PREY (2017) Discussion
Steam removed like a decade ago the possibility to opt-out of automatic updates for installed games. The things you can do now is to stay offline, set restrictions to the download time and bandwidth, allow/prevent downloads during gameplay, always keep a game updated, only update it when a game is launched or always auto-update it.
* Updated game trainers and cheats daily
* Get notified when new cheats are added
* Request which games get new trainers
* Priority support with any problem
