A friend and I played the new mission posted on the Megacon website and enjoyed it. We used House 4. We ended up losing, as we wasted too much time finding the safe (and I mistakenly wasted a few turns trying to interrogate the Administrator when the mission required only that she be captured). As we were nearing the room with the safe 4 SecFor IVs burst out of the stairs and took down a MERC. Game over.
During the game, we tried to use one of the Uniques in place of SecFors, and drew Salsa. We could not fully understand the card, which talks about him capturing MERCs. Are there rules about Salsa and Pesos somewhere, or rules about OpFor capturing MERCs?
We ended up deciding not to use him.
I probably would house rule it and say if they capture a merc, that merc is placed on one of the two cards. They then try to escape. If they escape the merc is dead otherwise if the one carrying a merc is killed, the merc is placed and back in play.
