FFG is starting to roll out more info for Worlds. No word on Runewars prizes yet, but they have revealed the schedule and side events.
The main event will be 4 rounds long, with a cut to top 4.
There's a team side event where each player provides a 200 point army, and all models on a side count as friendly to each other. No word on the armies being of the same faction.
There's also two painting competitions, one for armies, and one for single models.
