Unfortunately, it would appear that the unlimited grenade option itself no longer works. I have it enabled, and I'm running out of grenades.
Edit: Ah, I see. It only works for one of the secondary weapons, not both. It appears that the first selection in the loadout order receives the bonus. If you want to give the bonus to the item currently in the #2 slot, you need to disable the infinite grenades option first and completely change the secondary weapons loadout first, as even if you swap slots the bonus sticks with the weapon that was originally in the first slot - even if that weapon has been swapped out afterwards.
When I play the game without the trainer I have no problem. But when I open the trainer and press F1 and then enter the codes I wish to enable the game crash and my machine shut down.
Anyone had this problem???
The game run perfectly with no crash when the trainer is not open.
