Yesturday, Codemasters put on an event to promote Dirt 3 and also unveal the games multiplayer section.
The three videos below show off the three seperate multiplayer modes. Invasion sees cardboard cut-outs of robots and skyscrapers be dotted randomly around the arena; players gain points for smashing robots and docked points fitting the skyscrapers.
Transporter is practically a rally version of capture the flag. The thrid mode is outbreak where a player in the lobby is infected and attempts to infect everyone else within 2 minutes.
Comment below what you think of the footage.
