Nintendo shared screens and details for Fire Emblem Awakening with the press today.

While we've heard most of the details before, there is mention of three areas of wireless support:

Dual Tag

Team up with a friend for cooperative battles via local play. Each player selects three participants.

Street Pass

The custom My Unit character you create can be traded with other players via Street Pass. Characters you receive will support you buy joining your army.

Spot Pass

You'll receive gaiden maps via Spot Pass.
