Valve has announced that it's working on a sequel to the hugely popular online RTS title, Defence of the Ancients.
According to Game Informer, the sequel runs on Valve's Source engine and includes voice chat. Visuals have been upgraded but remain faithful to the original's cartoony style.
There will also be a new coaching system which lets veteran players help out newcomers.
Defence of the Ancients, or DotA as it is more commonly known, began life as a custom scenario for Warcraft III: Reign of Chaos. An anonymous developer known as IceFrog has been custodian of the mod ever since, making regular updates.
Valve has confirmed that IceFrog will be working with them on the sequel.
DotA 2 will launch on Mac and PC in 2011.
