Edit: Just dug up the announcement of the first two free maps from back in January:
First up is The Cruiser, a close-to-mid-range combat map set in the confines of a decommissioned ISA cruiser. Consisting of tight, claustrophobic corridors and interconnected compartments, the key to dominating this map is identifying and controlling its choke points.
Next is The Hangar, a wide-open map situated in the hangar bay of one of Helghan’s humongous mining spires. In addition to the main area, which offers long lines of sight suitable for sniping, the map contains alternative routes that will need to be secured for full control.
