The trainer does work just some of the options don't. Now I did this in operations (with bots) and Unlimited Fury and Weak Enemies don't work. Unlimited Health and Armor kinda works but I can still die if I get hit hard enough or enough enemies hit me. That or the health and armor bar shows full but I still take damage as if I dont have unlimited health.
Since you obviously failed to read the readme:
This trainer is exclusively made for the SINGLE PLAYER mode of the game and it does works only for THE CAMPAIGN SINGLE PLAYER MODE and it won't work for the OPERATIONS even in solo mode because the operations and progression are both server sided so you can't use the trainer to alter or increase your progression.
Added more code to prevent crsashes and unlimited health should no longer affect the enemies even bosses.
will look into the other possible options like blue and purpule currencies but i need more info, where these currencies can be spent and how they can be earned? i need well detailed instructions.
The colored currencies are earned by finding these floating skulls in the missions at randomized set spawn points. You have to play harder difficulties to get better ones from green to purple to gold. It will tell you what's in the mission when you look at mission description.
Spending them is done at the armory to either upgrade the tier of your weapon to let you buy better variants or to master already purchased weapons. You need to get weapon EXP to level up the weapons before you can spend them to upgrade the tiers.
