People have different tastes and this is a way to provide a way to play the scenario with certain features added (or removed, depending on how you look at it).
Remove ACE, then. It's simply not worth my time without some incentive (look at my wishlist for ideas).

This version is "Ravage plus". What does that mean?
Constant AI Raider and Renegade spawns. In the others when certain tasks are completed they are turned on for a short period.
Constant ambient zombies of all types.
Hordes in a few locations.
A few zombie blacklist areas.
A few safe zones from the raiders and renegades.

The tasks are the same but the environment has far more activity.
