Hi, providing save game, it is right before fighting of Deathbringer, hope it will help
Toggle off team health if it's on, maybe that's it.
With unlimited health, and with weak enemies, and ghost hunter I can walk right up to deathbringer and fire two shots at it and it dies instantly.
best,
Cal
DON'T USE THE UNLIMITED ITEMS IN THE ANCIENT ARMORY MISSION!
Turn it off when you use the power cells in the lock. If you keep this option on and unlock both locks with it, then collect the ancient armour your mission will be bugged and stuck on "collect 3 power cells" and you won't be able to use this armour.
There are several other missions that are broken with the unlimited item option activated. Luckily the game creates a lot of auto saves to revert to.
