NOTE: Beta version: There may be changes and limitations until it is ready from production.
You play game rounds with one or more opponents on a limited area and for a limited time. You build production an control buildings and compete for control of the ground. You may also later attack you opponents buildings. You can also research and increase you output from buildings.
Location based walking game:
You have to actually move to build buildings and attack them.
You may recenter the game board on the map on your real location and may therefore play anywhere. You still have to walk though :-)
Hall of fame:
You may play ranked games, that give you reputation and increase your ranking.
