I edited the default campaign Mig-21bis "Stillness in Time" to make it more playable, intense and a bit more simple.

Installation:
Unzip the file and put the folder "MiG-21bis-Stillness In Time EDIT" in:

User / Saved Games / DCS / Mission / Campaigns / en.

I recommend using the livery you find "USAF Operation Black".

EDIT:
-Aircraft: Enemies and Friends and their equipment
-Task
-Triggers
-Score

A Council for 4N mission "Titans Rage": stay away from the fray at least until the enemy aircraft were halved

I did several tests, I hope everything works correctly
Enjoy and Good Fly.
