All maps are designed for battle-mode, with spawn points enabled for deathmatch also.

About update 6.1. While testing I discovered that somehow the entry points for team 1 weren't working on three of the maps. I don't know if I accidentally uploaded old versions of the maps or if I just forgot to rename the entry points. Either way, it's fixed now, and Boulevard, Cradle and Frontier should now work as intended.

Sandcastle is a desert town map with three paths between the two teams, and a small plaza in the middle.
Updated in 3.0: several changes, mostly aesthetic.

Next is Boulevard. A swadian city with a central elevated highway in between the winding streets.
Updated in 3.2: The map has been made smaller, and refocused so that several of the side-streets become tactically plausible as pathways.
Updated in 6.1: Spawn points have been fixed.

The third map is Frontier. This is a more open map, set on farmland bordered by a river and various forests. Cavalry and archers should have a good time of it, but there is cover for infantry if they can get to it.
Updated in 3.1: The central field now contains several more focus locations that should keep things interesting and even up the balance between play-styles. The outpost has been moved closer to the main road.
Updated in 3.2: The map now contains about half as many trees as it did previously.
Updated in 4.0: The small hill under the outpost has been made more prominent.
Updated in 6.1: Spawn points have been fixed.

Next is Cradle. This map contains a small town next to a mountain lake. There are multiple paths of attack for both teams through the streets, via the forest or along the shoreline.
Updated in 6.1: Spawn points have been fixed.

Then there is Hillside. This is an open map containing a relatively gently sloped hill with a path curving around the side.

Finally, Dryport. This is a seaside town with pathways through the streets, as well as ladder access to the central rooftops.
Updated in 6.01: Moved a ladder so that no team has an advantage in getting to the rooftops.
