Panzer Corps 2: Frontlines - Westwall is a DLC for the strategy game Panzer Corps 2. It places players in command of US Army formations tasked with breaching the Siegfried Line from September to December 1944. The campaign begins with rapid advances but escalates into a difficult fight against entrenched German defenses across varied terrain, including fortified zones, the Huertgen Forest, and the Roer Plains, before shifting focus to Lorraine and the Saar region. The add-on introduces new battles, visuals such as custom officer portraits and campaign maps, and a dynamic difficulty curve. It also adds unique units like the Field Armor Sherman Tanks, characterized by improvised armor, and the Dodge WC-63 Truck transport, alongside new Westwall fortifications like Dragon’s Teeth and Pillboxes.
