Tower Defense: Night Survival

The power is out. The stairwells are open. The generator in the middle of the floor is the only thing still running — and the infected are already climbing.

Tower Defense: Night Survival is a top-down tower defense shooter where you don't just place towers, you fight beside them. Three ways onto your floor: the left stairwell, the right stairwell, and the elevator shaft down the center. All three lead to the generator. Build, shoot, repair, survive until dawn.

BUILD AND SHOOT AT THE SAME TIME
• 4 towers to drop on the lane mouths: machine gun turret (all-round DPS), tesla grid (area shock damage over time), barricade (soaks hits and reroutes enemy pathing), slow tower (chills everything in range)
• Upgrade any tower to level 3 with coins, and repair it when it gets chewed up
• Aim and fire yourself — limited magazine, real reload downtime, headshot crits for 1.75x
• Dodge roll with invincibility frames when you get surrounded
• Hold E to repair the generator, but you can't shoot while you repair. That trade-off is the whole game.

TWO LANES BREAKING AT ONCE
Towers stop the small stuff. Armored infected walk straight through them, and that's when you have to run the lane yourself. Red alert arrows flash on the edge of the screen the moment a lane drops below safe — the left side needs your gun, the right side's barricade is being eaten through, and the generator's health bar is falling. This is tower defense that makes you pick.

DAYTIME: SCAVENGE THE FLOOR
90 seconds of quiet between nights. Crack supply crates for coins, blueprints and ammo perks, escort survivors to the elevator for a payout, then spend everything on defense before the lights go out again.

30 NIGHTS, THEN ENDLESS
• Campaign: survive the full 30-night infection season, with a boss night every 3 nights
• New enemy types arrive on schedule — sprinters, hammer brutes, armored infected, shield carriers, bats, exploders and layered bosses. HP, speed and count climb every single night.
• Clear the campaign to unlock Endless: the difficulty curve keeps extrapolating and the wave mix goes fully random. Your score is simply the night you reached.
• Meta progression: every run pays out chips based on how many nights you held. Spend them in the main menu shop on permanent upgrades, new tower types, new guns and new heroes.

BUILT FOR TOUCH
Left thumb is a virtual stick for movement. Right thumb auto-aims at the nearest enemy and holds fire. Drag a tower icon from the build bar onto a highlighted slot — one finger, tower placed. One-tap buttons pop up for repair, scavenge and survivor escort when you're close enough.

NEON NOIR HORROR
Dark concrete corridors, alarm red and arc blue. The elevator shaft is a blue column of light running down the middle of the screen: the walls glow red when something is climbing it, and it turns gold when you get a survivor out. You can read the entire night at a glance.

FREE TO PLAY, AND HONEST ABOUT IT
Tower Defense: Night Survival is free with optional ads and in-app purchases. Every single item in the chip shop can be bought with chips you earn by playing — purchases only shorten the grind: double chip cards, a dawn revival capped at one per run, night starter packs, and cosmetic hero/gun skins and tracer effects. Boosts are time-limited and value-capped. No permanent invincibility, no one-tap win.

Single player, no login needed. Campaign progress, chips and your best endless night are saved on your device.

Grab a gun, patch the generator, hold this floor until sunrise.
