Fight for survival in NYC’s deadliest subway warzone.
Relentless aliens. Limited ammo. One lone defender.
Upgrade, strategize, and survive wave after wave of invasion.
New York’s underground has become a warzone. Aliens have invaded the subway, and you, a lone security guard, are the last line of defence for a train full of terrified passengers. Armed with only a pistol and limited ammo, you must fend off relentless waves of extra-terrestrial attackers while scavenging the tunnels for vital supplies. Every bullet counts and every decision could mean survival or annihilation.
As the invasion intensifies, so does the challenge. Earn points by eliminating enemies and upgrade your weapon with powerful attachments like scopes, flashlights, and thermal sights. Unlock devastating sub-weapons such as grenades, fortify key areas by locking doors, and strategize your defence against increasingly cunning alien foes. Some will charge straight at you while others target the train’s defences, forcing you to multitask and make split-second tactical choices.
With each wave, the stakes grow higher. Aliens become faster, stronger, and start using weapons against you. The subway transforms into a battlefield where survival demands sharp reflexes, precise shooting, and smart resource management.
Do you have what it takes to hold the line and stop the invasion before it’s too late?
