Undead Invasion
Undead Invasion drops you into the zombie apocalypse with nothing but a basic weapon and a will to survive. Waves of undead pour in, and your job is simple: don't die. It's classic survival shooter energy, refined for browser play.
What is Undead Invasion?
Undead Invasion is a browser-based zombie survival game where you fight endless waves of undead enemies while managing resources and upgrading your arsenal. The format is familiar to anyone who's played wave-based shooters: survive one wave, prepare for the next, repeat until you can't.
The core loop balances action and preparation. During waves, you're shooting, dodging, and trying not to get overwhelmed. Between waves, you're spending earned currency on better weapons, more ammo, or other survival upgrades. That rhythm of tension and relief keeps the experience engaging across long sessions.
What makes this survival shooter work is the escalation. Early waves are almost relaxing, letting you find your footing. But the zombie count grows, tougher variants appear, and suddenly you're fighting for every second of survival. That curve creates natural drama without scripted events.
Undead Invasion appeals to players who enjoy resource management under pressure. You're constantly making decisions: save money for a big upgrade or buy immediate survival tools? Take risks to kill more zombies or play safe and potentially miss resources? The zombie survival game genre rewards strategic thinking wrapped in action gameplay.
It's also satisfying in a primal way. There's something deeply enjoyable about mowing down waves of enemies, regardless of whether they're zombies, aliens, or anything else. Undead Invasion delivers that power fantasy while keeping challenge present.

Tips & Strategies
Master the mechanics with these pro insights.
Keep moving in circles or patterns rather than straight line
Keep moving in circles or patterns rather than straight lines. Zombies in most survival shooter games path predictably. Circular movement bunches them up for efficient kills while keeping you safe.
Prioritize fast zombies
Prioritize fast zombies. Slow zombies are manageable even in groups. Fast zombies disrupt your positioning and create chain-reaction problems. Take them out first in Undead Invasion.
Don't reload in the middle of a swarm
Don't reload in the middle of a swarm. Either kill what's threatening you first or reposition to safety. Reloading at the wrong moment in a zombie survival game is one of the most common ways to die.
Invest in weapon upgrades that increase damage per shot earl
Invest in weapon upgrades that increase damage per shot early. Fire rate matters less when ammo might be limited. High damage means fewer shots needed, which means more zombies cleared per resource spent.
Learn the chokepoints
Learn the chokepoints. Most maps have spots where zombies naturally funnel. Holding these positions maximizes your damage output while minimizing angles you need to watch. Undead Invasion rewards positional awareness.
Save powerful weapons or abilities for emergency situations
Save powerful weapons or abilities for emergency situations. If you burn everything on regular waves, you'll have nothing when a boss wave or overwhelming surge appears. This survival shooter rewards resource conservation.
