Infinite Vehicle Health, No Overheat on the Weaponry and Instant Cooldown all Work.
Instant Cooldown has never been exactly pin-point working with the trainer. - The Abilities themselves start playing up with it on occasion. They go red and can't use them again and never recharge, in example the Clone Commando "Buff" does so.
Infinite Player Health does not work and each time you try to activate it on Wemod, it deactivates automatically within a second or two.
The game did update yesterday, with the "Cooperative Update" - Which reformed the AI, added Instant Action, COOP, added Clone Commando's and Felucia. (Apparently Reformed the AI, ain't entirely sure on that half.)
