The only game play options missing that would be killer are stealth and never wanted.
Being stealthy is next to impossible in this game.
I am guessing the unlocks are impossible like all weapons or level 10 skill challenges, always love those in the Far Cry Games.

Can confirm this. Am having the same issue. Running the game in windowed mode and selecting the trainer and enabling the option works though.
