From a post Alex Watkins put up yesterday: (I've stripped out the non X-Wing related info)

FFG European Championships side event structures

Star Wars X-Wing
Hangar Bay:
These will work in pods of 8 players. Players need to bring with them two lists (you may bring one if you wish).

Each list must not contain any ships, names pilots or upgrades that appear in the other list.

The two lists may be of the same faction though if you wish.

Team Epic:
Teams consist of two players. Each player brings a list of no more than 200 points.

Full details on this format can be found at www.fantasyflightgames.com/en/products/x-wing

Team Event:
Teams consist of three players. Each player has their own squad of 100 points.

You play against another team of three.

To win the round your team must win at least 2 of the three matches.

Your team is then awarded 1 point.

The number of rounds will be determined by the number of players.

Prizes will be based on the finishing record of the team.

If you do not have a full team and you want to join in then please sign up and we will do our best to fill up teams.

Additional Info from a blurb Alex sent out around a week ago: (Again, non X-Wing details have been stripped out)
