Nucleus will be build into all of the EA Sports titles, Spore, and Battlefield Heroes. The system will allow players to play games together, and also track scores and other game data across platforms.

Maps, weapons and other Battlefield Heroes downloads will be managed on the service.

Napster creator Shawn Fanning then appeared on stage, detailing a new custom achievement system using the existing Rupture network, which was purchased by EA last month.

Using an open API implemented in scripting language Lua, players will be able to create achievements for eachother and challenge their friends to complete them across the Nucleus network.
