About this game

Urban Siege Line is a 2D action shooter that puts you in charge of defending a ruined city line from relentless zombie waves. You move between three parallel lanes, fire at incoming foes, switch among three weapons, call in air support, deploy a support squad, and toss grenades while upgrading your armory to survive each mission.

The game feels rewarding because every lane shift and weapon change matters, and the mix of air strikes and squad deployment adds tactical depth. Play it directly in your browser for free on desktop or mobile—use the arrow keys and hotkeys on a computer, or the on‑screen button on a phone, and pause whenever you need a break.
