Tower Defense: Night Survival

The generator is the last light in this building. Keep it running until dawn. Three ways in — left stairs, right stairs and the elevator shaft — and every one of them leads to your generator. Turrets alone will not hold. You have to run the floor yourself, gun in hand. BUILD AND SHOOT AT THE SAME TIME • Machine gun turrets, electric floors, barricades and slow towers — drop them on the lane mouths, upgrade to level 3, repair them mid-wave • Auto-aim and fire with one thumb; hit an enemy's front for a 1.75x headshot • Dodge roll with brief invincibility, and never get caught reloading TWO LANES BREAKING AT ONCE Turrets shred the small infected but stall on armored and shielded ones. A red alarm flashes on one edge of the screen, you sprint to plug that hole — while the barricade on the other side is being chewed through. SCAVENGE BY DAY, HOLD BY NIGHT 90 seconds of daylight: crack supply crates, grab blueprints, walk survivors to the elevator for gold. Then the lights go out.
