For the Covenant building, see Covenant Spire.
Spire is a multiplayer map in Halo: Reach. It was first talked about very briefly in the Bungie Weekly Update for July 16, 2010, and the map's official name was revealed in the Forge World ViDoc, which launched on July 22, 2010.
The map is set on a beach with rocky cover. The focal point of the layout is an immense, towering Covenant shield generator spire. The lower portion of the structure is a flat dome shape with an open tunnel running underneath. The upper portion is an enclosed circular structure supported by nine energy beams and has an energy balcony that encircles it. The top of the spire emits an energy barrier that envelopes the playable area. There is another smaller Covenant building to the side of the spire. The map is compatible with Invasion, and is the opposite of Boneyard, having a Spartan offense and Elite defense. It features a Falcon, a Banshee, and a Warthog. Both the bottom and upper levels of the map are playable areas. The map is compatible with the race gametype.
