This pack contains 3 different bo105 helicopter versions for vanilla bf2. You will find one with "HOT" missiles with its pilot on the left seat being able to fire those missiles and there´s also one modified in a special way: some realistic flight behaviour elements were added to its flight physics. Finally there´s an Arcade version (right pilot´s seat) with a single cannon and a headtracked missile. You will find installing instructions inside each folder - one for each helicopter. Don´t forget to check out my SA342_PACK, too. It can be found in the bf2 add on section. Enjoy!
