As the title suggests.
Which PC game is that ?
Are you referring to The Final Station, which is up on STEAM, or some other title ? And, btw, it would be nice if you can also provide the full LIST of trainer options you actually want for this game, rather than providing just the game’s name.
That is it.
Options would be as per usual life and ammo (that’d be convenient enough) But at the end of the day a trainer should overpower a basic CE function. So other functions can be unlimited health and hunger for the passengers and the train’s machinery, although to be honest that is easy so far.
