One of the maps I worked on during the last days. It is a 3 vs 3, 64 x 128, vertically symmetrical map. Each team is located behind large mountains, in an open area which can only be accessed through a tight path. Allies work together to protect the main entrance while making their way through the enemy's. Resources are located inside the safe area, both near the starting points as well as a few places around them, but also outside the "fortress" in open fields for those who wish to risk establishing a castle there. A lake divides the map vertically, which can be crossed in two opposite points where there's shallow water.
