Dawn of the Tiberium Age (DTA) is a stand-alone mod that combines Tiberian Dawn (C&C 95) and Red Alert. While classic mode gets as close to the original game-play and balance as possible, Enhanced mode provides improved game balance and a lot of fun new stuff. DTA features many customization options for Skirmish and multiplayer (where you can play as GDI, Nod, Allies and Soviet on over 200 maps), challenging original singleplayer missions, as well as co-op missions. Since this is a stand-alone mod, you don't require anything but the mod itself to be able to play: the original game is not required.
This is Rampastring and me (Bittah Commander) playing through the "Double Team" Co-Op mission ( Moddb.com ) on hard difficulty.

Glorious!
Its an almost impossible mission with the odds stacking against the player so unfairly that it hurts. Its what C&C was original like and about, we need a return to the classics in RTS games, the new ones are stupidly easy and have really tiny battlefields (maps).
Note that this is on Hard; the mission is far easier on Medium and especially Easy. I try to make the difficulty levels so that hardcore gamers will get good challenges, while casual gamers are also able to beat the missions by dropping the difficulty level.
I still miss those days of puzzle RTS where you only have a limited number of units then having to complete a mission with them
