Most parts of CFS3 have been totally replaced, renewed or improved dramtically.
Not only High Res Scenery, more Scenery variations and types, dramatically improved AI (computer pilots),
Physics, Flight models, Damage Models, Aircraft Models, Effects, Ground objects and scenery,
and finally and most importantly, with a FULLY NEW total WW1 replacement for the CFS3 campaign engine.
This is "OFF Manager" a NEW INDEPENDENT WW1 HISTORICAL CAMPAIGN ENGINE! with even more features.

The campaign manager is DYNAMIC in that every mission is new, dynamically created, different. 
Craft are flying real missions not scripted or repetitive, no "spawning" as you get close.
There is a world going on out there. 
No you can not change the course of the war - even the Red Baron himself could not do that ultimately and few could in WW1! 
This is about the struggle and the fear, the danger and the excitement in the air in WW1 high above the ground war!

Many features are a first in a flight simulator, or for CFS3 and we believe the scenery is some of the best,
if not the best, seen in currently available flight simulators. 

It transforms CFS3 into a new flight simulator experience. 
Although BH&H is designed to be a realistic experience by default, we have added many options so it can be made easier or harder
if you wish to tailor more to your taste!  Also in game visual aids can be on or off depending on your preferences!
