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.
With the latest update (v9.7.0), we made the Chrono Vortex last 50% longer and deal more damage, but also applied a slight delay between its appearance and when it starts dealing damage.
This makes it less of direct a "delete button" for enemy armies (at least if the enemy notices the vortex in time), but instead it is very powerful for denying an area for its duration. Place one in the enemy's backline when you're fighting on a bottleneck and there's no retreating alive for the opponent.
What a lovely vortex.
