Ok, so this came up last week. We peacefully resolved it, but I want to know what the forum thinks. I should be able to keep this spoiler free.
We were playing Indebted (Garkhaan's mission) and you can see it is several buildings connected to a forested area. We played it far enough along that there was enough threat to make the ATST a viable option. Problem is, there are points where the only active deployment points are *inside.
Rules say massive units can't go on indoor tiles. Rules say deploy to the nearest legal point. Knowing those rules, we came up with a couple options.
1) deploy the ATST to the doorway as its the nearest legal space (even if that happens to be 8+ spaces from the deployment point)
2) piss off, no ATST for you this mission, bring something else
Anybody have any idea how to rule this? The rules seem to favor option 1, but the distance stretches the bounds of reasonability. I dont know, and I haven't found anywhere this specific question was asked already.
