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 100 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.
Allies will be able to build the spy in version 1.16. After infiltrating a structure it will reveal information that's relevant to that structure:
-For factories it reveals which unit or structure is being produced by that factory.
-For refineries and silos it will reveal the amount of resources that are stored in that particular refinery or silo.
-For power plants it reveals how much power the player has in total, as well as how much is being drained.
-For radars it will reveal (and keep revealing) shroud around any unit of the player whose radar you infiltrated.
