Money: Press hotkey or use editor to change your money. Changes will not be immediately visible ingame. You have to buy or sell something first.
Super Running Speed: While active your character runs much faster. Be careful as the turning around speed is still the same so your character may stuck in path finding when trying to run around houses. Either lower the speed value on the trainer, or use this option when you have to pass a straight way.
Editor (Inventory): Changes will not be visible immediately. You may have to upgrade your inventory ingame before you can see the changes.
