At Gamescom today Activision unveiled the online modes for Skylanders
Each Starter Pack offers six tracks out of the box – two each for Land, Sea and Sky. If playing locally it seems you can only race against one other human opponent. Online however you can challenge up to three other players.
This Starter Park racing is extended by new Racing Action Packs. Each of these (of which there is one for Land, Sea and Sky) unlock a variety of content. They include a SuperCharger Skylander and vehicle paring along with a specific villain trophy.
