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.
The new Soviet main menu for DTA 1.15. Tomsons26 remade the original Red Alert main menu background in high quality, which I slightly edited to make it fitting for DTA.
Now I wonder if this would lead to a possibility of accessing the Giant Ant Missions like you could in old legacy days? Would it be possible to do such a thing?
(This would imply if there were ever remakes of the Giant Ant Missions, that came out to play.)
While it'd be a nice nostalgic touch, I don't think it'd be beneficial for us to hide content like that. If we had as many singleplayer missions as RA1 we could consider that, but in our current state we'll include all missions in the mission list.
