Are player-purchased fortifications (particularly buildings) considered (impassable) terrain or enemy models for the purposes of Deep Striking, mishaps, etc?

How would a Mawloc or Trygon that uses its' deep strike attack modes and happens to scatter into a Bastion be resolved?

All buildings are impassable terrain for deep striking models.

That's odd I can't find that rule anywhere. If it is an impassable building then yes it causes a mishap. Under terrain type for each fortification it lists what it is considered and none of them list impassable buildings that I can see:

Aegis: battlefield debris
Skyshield: Top is open terrain.
BAstion: Medium building
Fortress: multiple building types

So no deep strike mishaps unless an enemy unit is already there on top of the building on battlements or what have you.

Trygons reduce scatter to not mishap due to impassable terrain.

The Mawloc... needs an FAQ. I could see it either pushing the building out of the way or reducing mishap. RAW it mishaps though.

Where can I find this rule? I've always played that if I DS into a building I land on top of it.

It's the "building is impassable terrain" rule. When you deepstrike with Jump Infantry or Skimmers, you could treat the impassable top of the building as dangerous terrain instead. But with others? Mishap time.

Now, many groups, mine included, have a houserule that Deepstriking models treat top of buildings as dangerous terrain instead, but it is houserule.

Pg 93 Impassable buildings states that if ti is agreed at the start of the game that a building is impassable it follows the rules for impassable terain and models cannot go inside it for any reason. Fortifications ARE NOT impassable terrain because they allow units to go inside of them and/or allow units to be deployed inside of or on top of them.

Fortifications have battlements on top of them. Battlements are covered starting on pg 95. There are no exclusions from deepstriking onto battlements since there is nothing stating they are impassable terrain. IT instead says that they are able to be occupied by units from either side thus making it passable terrain. Thus there is no deep strike mishap which occurs from landing on top of a building.

If is only a mishaps as such if it is declared as an IMPASSABLE BUILDING at the beginning of the game.

The above 2 posters are incorect, it is not in the building rules, it is in the deep strike rules.

Page 36 under the Deep Strike special rule. Next to last paragraph in the left hand column, last sentence says that buildings with the exception of battlements are counted as impassable terrain for deep striking units.

Something tat intrigues me is the beginning of the buildings section (second paragraph I believe), states that buildings take aspects from the transport rules, then it goes on to explain the key difference is buildings can't move nor can they be destroyed.

Does this mean that a mawloc can attack a building it lands on and (more hilariously), force the building to move?

I guess this would entirely depend upon whether or not buildings count as enemy units

If the Mawloc lands on a building it Mishaps, due to the fact (as pointned out under DS rules) buildings are impassable.

but TftD specifically states if you land on enemy models, you do not roll on deep strike mishap, but instead do an attack. So if buildings you have purchased are considered enemy models, does it work?

No, because they are still Impassable terrain. Deep Strike specifies that if you land on top of enemy models or in impassable terrain you mishap. TftD overrides the DSing on enemy models but not Impassable terrain.

Okay, I can see that. Still, moving a bastion as a dune worm pops out would've been pretty cinematic =(

Oh I agree whole-heartedly. Especially if as it comes up, it leaps into the air bites onto a Flyer, and crashes the Flyer into the ground....

Unfortunately the rules don't quite allow my little scenario to fully play out.

Did not see that. Still it means fortifications are all able to be deep struck into because they have battlements or are considered open terrain. Ill have to read the deep strike section later as I don't have my rule book on me at the moment.

There is a small bit of info missing from Time Wizard's post of the rule on pg 36.
It states: "Deep Striking units count non-ruined buildings (except for their battlements) as impassable terrain." It is minor difference in text but could save your unit if it scatters on top of a building with battlements on the top of it as opposed to building that has no battlements on it.

You can deep strike onto a battlement, but you cannot deep strike into a fortification.

The battlement and the fortification are parts of a multiple part building.

Fortifications are not considered open terrain, and the battlements are neither area terrain not dificult terrain.

They use some of the rules for vehicles as far as occupying the building by "embarking and disembarking", but they are not vehicles.

So a Mawloc could technically Deep Strike onto the battlements of a building? Basically going through the building and coming out on top?

Interesting idea! Have to think on that! I'll get back to you.

IMO, more hilarious than the Mawloc leaping into the air and bringing down a flyer.

<Mawloc slithers in through the front door of the Fortress of Redemption. He tips his hat to the space marine guard (don't ask me why he has a hat, he just does).>

"Hey Bill."
"How's it going, Mike?"

<The Mawloc delicately pushes the call button with one of his talons>

"How's the wife?"
"Oh she's doing well. Expecting a new brood of hatchlings in the fall":
"That's great news! Think you'll have any luck keeping her from eating this one?"
"We'll have to see, she gets in those moods and...well you know the rest"

<Elevator dings>

"Well, give her a hug for me when you get back."
"Will do, take it easy."

<The Mawlock squeezes himself into the elevator and the doors shut>

<Muzak plays in the background. The Mawloc quietly hums the tune to himself while staring impassively at the floor>

<Elevator dings and the doors open at the top floor>

<The Mawloc slides out and the doors close behind him>

<He glances at the ceiling and clears his throat>

Meanwhile...

<On the battlements on top of the Fortress, a squad of marines is desperately firing down into the oncoming Tyranid horde>

"Target left!"
"Need another mag!"
"Put some damn fire on those Gargoyles!"

<All of a sudden the roof explodes upwards as the Mawloc bursts out>

"RRRRAAAAAAAAWWWWWWWGGGGGG!!!!!!!"

<Marines go flying in all directions, several over the side, only to fall to their death>

I love it! Especially the muzak!

However, the battlement is still part of a building, and only infantry units can go into the building, and the Mawlok is a monstrous creature.

So I don't think the Mawlok can use it's rule to deep strike into or onto a building.

Jump infantry and jet pack infantry have specific permission to move directly onto a battlement if their move is sufficient.

Oh I agree, the imagery just cracks me up though

Buildings sides have Armor Values, so couldn't a Mawlock come up under a side of a building and attempt to destroy the building?
I dont play nid's so I dont know the rules regarding Mawlocks.

Well, the hilarity behind that would be, if the mawloc were allowed to attack the building, the Nid FAQ states that TftD moves things that normally can't be moved, so your bastion kind of "scoots" over a few inches with your guys inside
