Survive 90 Nights

Survive 90 Nights drops you into a harsh wilderness where the sun brings brief respite, and darkness summons relentless creatures. Each evening, they emerge from the shadows to test your shelter, your wits, and your courage. During daylight hours, you scour the surroundings for wood, stone, and scrap to reinforce your walls, craft traps, and forge weapons. The quiet hours are your only chance to prepare before the next onslaught begins. As the weeks drag on, the danger multiplies. Early skirmishes give way to coordinated sieges, and new enemy types with unique behaviors force you to adapt your strategy. You'll need to balance resource stockpiles, repair damage, and decide where to place your limited defenses for maximum effect. Every choice matters—one careless night could end your run. The goal is simple: survive all ninety nights and break the curse that haunts this land.

What is Survive 90 Nights

In Survive 90 Nights, your shelter is your sanctuary, but each sunset brings a fresh wave of horrors. Can you hold the line for three full months?

How to Play

Each day, explore the map to collect materials and craft defensive tools. At night, position your traps and weapons to fend off the monsters, then repair and upgrade when dawn breaks.

Tips for Playing

Prioritize reinforcing your main gate first—it bears the brunt of most attacks.
Store extra wood and stone; you'll need them for quick repairs after heavy fights.
Test different trap placements—corridors funnel enemies into kill zones.
Upgrade your crafting bench early to unlock advanced gear sooner.
Keep a reserve of sharp weapons for the final stretch when monster variety spikes.

Frequently Asked Questions

What happens if I fail to survive a night?

If monsters breach your shelter and destroy your core, the game ends. You'll restart from night one, losing all progress.

Can I play during the night as well?

How many different monster types are there?

There are over a dozen enemy types, ranging from fast runners to heavy brutes. New ones are introduced as nights progress, keeping the challenge fresh.

Is there a way to skip nights or save progress?

The game saves automatically after each night. You cannot skip nights—each one must be survived, though you can replay earlier levels for practice.

Are there any hidden secrets or bonus objectives?

Yes, scattered across the map are rare artifacts that grant permanent upgrades. Finding them can tilt the odds in your favor, but they're guarded by stronger enemies.

Does the game require internet connection?

No, the game runs entirely in your browser and can be played offline once loaded. However, some features like cloud saving require connectivity.
