Notes

The trainer now works best if you activate at main menu.

Also you may want to activate all options ON then OFF at the main menu to make sure that the correct code is created and diverted.

Unlimited Health:
Toggle on and the trainer will try to keep your health full.  Things like LAVA and certain scripted deaths are instant death and have nothing to do with health.

Unlimited Stamina:
Toggle on and you have unlimited stamina.

No Reload:
Toggle on and most weapons when fired will not need to be reloaded.

Unlimited Ammo:
Toggle on and when you reload, the current weapon will not have ammo decrease.

Super Speed:
Toggle on and you can move faster.  The value in the trainer can be modified.

Inventory Size Multipler:
Toggle on and the inventory is multiplied to a size by the value in the trainer.

Volcano Timer:
Toggle on to keep the timer from counting down.

Production Speed:
Toggle on and when you craft items at the Production Station, they are finished almost instantly.

Easy Craft First Stations:
Toggle on and when you Craft Items in the Production Station, even if you do not have enough materials, when you add them to the queuet they are created.  May work in most stations!

Easy Craft Fake Inventory:
Toggle on and most stations, the amount of inventory you have of the items needed is FAKED such that the station will allow you to produce the item in most cases.  TOGGLE BACK OFF and DO NOT USE unless crafting or producing items, to prevent unintended consequences.

Toggle on and the trains/drills have unlimited energy.

Mega Core Slots:
Toggle on and the trains/drills have plenty of core spaces.
