This haunt seemed pretty heavily favored towards the traitor, which actually makes sense given that the traitor's ending lines up with the movie. The Synchronize Your Swimming task seemed especially impossible given the typically low amount of items held combined with the fact that the heroes can only Time Warp once each.
It did seem favored toward the traitor, but in a game with only 2 heroes, we passed 3/4 farces and all three radio tower climbs. Traitor was Brandon, heroes were Ox and Zoe, and we could not for the life of us fail the Speed roll of 3+. The "synchronize your swimming" part sounds insanely difficult, and we didn't even get to try that part. However, between the two of us, we had like 5 items and 6 omens (we didn't fail a haunt roll until there were 8 omens) so we would have had a pretty decent chance at passing the swimming part.
