Its not forbidden I personally always use cheat engine firstI hope it is not forbidden here to mention that until the trainer is ready to use, you can use "Cheat Engine" software to find low value items in your Backpack, and increase their number (for example zorkins or bulllets). You can also tinker in Outcast.ini file, in which you can strengthen your character for example. With these modifications the game is more playable, as the key elements cannot be added this way and conversations with different NPCs are also needed to advance in the story.
