Castle Siege

Castle Siege is a stage in Super Smash Bros. Brawl and returning in Super Smash Bros. for Wii U, based on the Fire Emblem series. Like Smashville, the scenery is not based on any particular Fire Emblem game. It is also the first Fire Emblem stage in any Super Smash Bros. game, as Super Smash Bros. Melee had no stages from that series.

The stage is set on top of a castle. It has numerous platforms, and in the background the rest of the castle can be seen, under attack from ballistae. However, after a certain amount of time passes, the stage transitions to the throne room. This has a few platforms above the main ground, held up by statues that can be destroyed. Several enemy soldiers can be seen in the background, including the general sitting on the throne. Finally, the stage transitions to an underground lava cavern. There, players fight on a rock platform balanced on a thin spire, which tilts back and forth depending on where players are standing.
