As Spintires: MudRunner unlocks on October 31 the answer is easy: We don't know until the game is released.
But as the game devs and publisher differ to Spintires it may need a new trainer request -> Link
Please use the update notification system to report a game patch, update or to report that the trainer may not be working with the latest version of the game. If 3 or more reports have been filed, consider BOOSTING the priority of this title for a faster turnaround on the updated trainer.
While waiting for an update to be released, you can use our free CoSMOS Gamehacking Tool to easily hack the game yourself. We have tons of video tutorials available for even those with no prior experience with memory scanners or gamehacking tools.
