About this game
Urban Siege Line is a 2D action shooter about holding a crumbling city against endless zombie waves. Enemies push in along three lanes, and your job is to keep them from breaking through. Timing your shots, swapping weapons on the fly, and knowing when to call in air strikes is what keeps you alive as the waves grow harder.
This is not just a shooting gallery. You can send in a support squad to hold ground for you, or lob a grenade into a clump of attackers to clear them in one blast. Resources earned from each mission go into your armory, unlocking heavier firepower and stronger defenses that change how you approach the next fight.
The game runs straight in your browser, so there is nothing to install before you start. Short missions make it easy to jump in for a few rounds whenever you have a spare moment.

Use the Up and Down arrow keys to change lanes and press S to shoot. Keys 1, 2 and 3 switch weapons, A calls air support, D deploys the support squad, and F throws a grenade. On mobile, use the on-screen buttons. Press P or ESC to pause.
