Ah, so I am not the only one who saw that they actually advertised a coop campaign!
I can understand the balancing issues with the campaign in versus mode, it would be very difficult since there are some flaws in the game campaign system - you have to more or less defend against tidal waves of enemies - and if you get lucky you can obliterate a far superior enemy by catching them retreating after a total defeat.

The new reference in RTS at its best!The Wargame series returns to duty, larger, richer and more spectacular than ever before. In Wargame Red Dragon, you are engaged in a large-scale conflict where Western forces clash against the Communist bloc.1991: the two blocs confront each other in a new theater of war, Asia, joined by various other countries: Japan, China, North Korea, South Korea. Wargame: Red Dragon is thrilling in single-player mode with its new dynamic campaign system, and also offers an extensive multiplayer mode where up to 20 players can compete against each other simultaneously. The Wargame series returns to duty, larger, richer and more spectacular than ever before.

But a coop campaign should not pose the problem of balancing anything - it should just be like it was done in ALB. One guy takes all decisions about movement on the map, and when battle starts - divide as best as possible the units partaking in the battle.
We had tons of fun with this in ALB. Even a campaign with more than one coop player would be highly appreciated. And it would bring so much more replayability to the franchise, for such a small effort.

Wargame Red Dragon Multiplayer Campaign Mod

1. 3)move the ZZWin.dat to the following address and overwrite the existing file when prompted: Wargame Red Dragon Data WARGAME PC 510064564. This mod is singleplayer only, it provides much larger and intense campaign battles. Campaigns have been modified.
2. RED had identified this before going into the battle, indeed in some ways before the start of the campaign, and when our guys brought out the ample short range AA there was little BLU could do but throw more helicopters in and hope.
3. In other words, rather than have Wargame 4 focus on one large area of operations, put it all over the globe so we don't have weird things like Scandi nations in a game set in the Far East with no campaign rhyme or reason as to why they're in the game.
