Here's a new single player / cooperative map.
You start off with an MCV and a spy.
You can use the spy to free Tanya from prison and to create another base behind the enemy.
Extremely hard even with two players.
Installation:
Single player version:
Copy scg01ea.ini and mission.ini files to \RedAlert folder.
Start allied campaign and it will be the first map.
Multiplayer coop version:
copy TotalWar.mpr to \RedAlert\Missions\
Start CnCNet for Red Alert, create a new game and find the map under missions.
edit: Should be \RedAlert\Maps\Missions\ instead!
Inform me of any issues and I'll try to help.
