Since Mozared is on holiday at this point in time, here's a message from your friendly neighbourhood data editor TheAlmaity. This WTE is going to last two weeks, and its theme will be: "Daelaam Ark". Though most of us have gotten acquainted with most of the HOTS tilesets by now, this one hasn't been used all too often yet. Therefore, these two weeks I'm looking for any kind of terrain in this specific tileset just to see what people come up with. Show us your Protoss ships, folks!
Looks good but somehow the ship in 'Enemy Within' had this alien spaceship feel while this one with the rectangles (the cliffs) looks a little bit like human interior, excluding the protoss texture and all. The rest looks alien enough.
Those are called terrain objects, they can be found by
a) Making a HotS map, or
b) Adding WoL Campaign dependencies.
and then looking in the terrain objects section of the terrain pallet. Some terrain objects also need a terrain object doodad, such as avernus refinery.
As the story goes it was an enemy ship that got capture by the dominion, there was a big fight on board to rescue a general and the ship was too valuable to just destroy it, so theres the story. Is an unfinished map as I like to work on it from time to time.
