About Urban Siege Line

Urban Siege Line puts you in charge of a defensive fight against successive zombie attacks in a damaged city setting. The action takes place across three lanes, so surviving depends on moving to the right position while choosing a suitable response to the approaching enemies.

Your toolkit includes several weapons, grenades, air support, and a support squad. Missions also let you improve the armory, giving the shooting loop a tactical layer beyond simply firing. Switching lanes and assigning support at useful moments keeps the battlefield active.
