This mission destroyed our team. My rules question pertains to the agenda deck.
I read this as "Move all Brood once toward the same random location." Consequently, they moved in a pack and we moved from location to location to try and head them off. Well, we did until there were 2 running around in a pack each with 2 copies of Tower Beast attached to them. That pumped them to 8 Fight, 6 HP (3-player game) doing 2 Damage & 2 Horror to each character present during the Enemy Phase.
Esoteric Formula, the only way to damage to a Brood, is a will-based attack. We were running Jenny, "Ashcan," and Daisy, none of which has a great Will stat. We killed the first 1, but were unable to kill any more with them running in a pack.
So, am I reading that correctly, or does each Brood move toward a different random location at the end of each Enemy Phase?
