Seriously!? Are they aiming for the mobile market perhaps? :lol:
As long as it is only in the single _player campaign_ I guess it's OK, but it better not be anything locked/unlockable in MP and especially COOP campaigns or missions.
I wonder where they got this idea from and that unlocks are a good idea in any setting (except, of course, if it is historically correct to unlock certain equipment at different times - and NOT at some pre-determined skill-level).
It will be interesting to see where this is heading...
