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 the new M.A.D. Tank that has been added in DTA 1.1117. In classic mode it functions exactly like in Red Alert, while in Enhanced mode it's a special unit that's even more powerful. The enhanced version won't self-destruct after stomping into the ground to cause the quake, but will instead keep doing so this until it un-deploys, is destroyed or the player loses power (although it doesn't drain power, it does require there to be sufficient power in order to operate). Selecting the deployed M.A.D. Tank will also show you a circle which exactly indicates the radius within which the damage gets inflicted.
