All About Undead Invasion
Undead Invasion is a pixel-style side-scrolling zombie battle survival game where players control a character fighting off constant waves of undead. The game combines zombie shooting and defense mechanics, requiring strategic thinking and quick reflexes to survive as long as possible.
If your character dies, you have to start from the very beginning, since there are no checkpoints or anything like that. So, try your best to survive every wave of zombies, earn in-game money, and then buy and upgrade your gear, ready to face tougher hordes with faster, stronger, and more varied zombie types.
Wave-Based Survival
Face increasingly intense waves of zombies, with each day bringing more challenging hordes. The longer you survive, the tougher the enemies become.
Weapon Variety
Use different weapons including firearms for ranged combat and melee weapons for close encounters. Each weapon type has its own advantages and strategic uses.
Defense Placement
Set traps and place barricades strategically to slow down zombies and create safe zones. Proper placement is crucial for survival.
No Checkpoints
Death means starting over from the beginning. Every decision matters, and careful resource management is essential for long-term survival.
Undead Invasion Gameplay Overview
Undead Invasion combines fast-paced action with strategic defense planning. The game follows a core survival loop: eliminate incoming zombies, survive the wave, earn coins, and upgrade your equipment before the next wave begins.
The pixel-style graphics give the game a retro feel while maintaining intense action. As you progress through days, zombie waves become more aggressive, with faster, stronger, and more varied zombie types appearing. This progressive difficulty keeps the game challenging and engaging.
The game features a mix of shooting mechanics for ranged combat and melee combat for close encounters. You can also use grenades to eliminate large clusters of zombies, and strategically placed defenses can significantly improve your chances of survival.
How to Play Undead Invasion
Undead Invasion is straightforward to understand but challenging to master. The goal is simple: survive as many waves of zombies as possible by eliminating them before they reach you.
Fight the Incoming Waves
Be prepared to face the first zombies! Move left and right, attack with your chosen weapons, and more importantly, keep distance from those undead. They will attack you when you get too close. So, kick your foot and use melee weapons if enemies get too close. You can also throw grenades to eliminate large clusters.
Use and Place Defenses
Before each wave or in between waves, you can place barricades, drop traps, and more to slow down zombies, giving the character more time to fight back and survive. Remember, proper placement is crucial. Position defenses in chokepoints where zombies must pass through, creating kill zones where you can eliminate them efficiently.
Upgrade Between Days
You earn coins by defeating zombies and surviving the full day. Use that money to purchase stronger weapons, health items, and, especially, additional defense items for surviving harder waves ahead. Prioritize upgrades based on your playstyle and the challenges you're facing.
Survive Waves of Zombies & Upgrade Your Gear
This is the core loop in Undead Invasion. Play strategically to eliminate any zombies that approach and try to harm you. Continue your defense until you're overwhelmed and can no longer hold your ground.
The progression system rewards survival with coins that can be spent on upgrades. Each upgrade makes you more capable of handling the increasingly difficult waves. Focus on upgrading weapons first for better damage output, then invest in defenses to create better strategic positions.
- Weapon Upgrades: Stronger weapons deal more damage and can eliminate zombies faster, reducing the pressure during intense waves.
- Health Items: Keep health items available to recover from damage taken during combat. Don't wait until you're critically injured.
- Defense Items: Additional barricades and traps provide more strategic options for controlling zombie movement and creating safe zones.
- Resource Management: Balance your spending between immediate needs and long-term upgrades. Sometimes it's better to save for a significant upgrade.
Using Defenses Strategically
Defenses are crucial for survival in Undead Invasion. Proper placement can mean the difference between surviving a wave and being overwhelmed.
Barricades
Barricades slow down zombies and create physical barriers. Place them in narrow passages or at key chokepoints where zombies must pass through. This gives you more time to eliminate them before they reach you.
Traps
Traps can damage or eliminate zombies automatically. Place traps in areas where zombies are likely to pass, especially in combination with barricades to create effective kill zones.
Strategic Positioning
The key to effective defense placement is understanding zombie movement patterns. Observe how zombies approach and position your defenses accordingly. Remember that you can place defenses before each wave or between waves, so use this time wisely.
Pro Tips for Surviving Longer
- Maintain distance: Keep distance from zombies at all times. They will attack you when you get too close, so use ranged weapons whenever possible. Only use melee when absolutely necessary.
- Use grenades wisely: Grenades are powerful but limited. Save them for large clusters of zombies or emergency situations where you're about to be overwhelmed.
- Plan your upgrades: Think ahead about which upgrades will help you most in upcoming waves. Don't just spend coins immediately—consider your long-term survival strategy.
- Learn zombie patterns: Different zombie types behave differently. Learn their movement patterns and attack behaviors to anticipate threats and position yourself accordingly.
- Don't panic: When waves get intense, stay calm and focus on eliminating zombies systematically. Panic leads to mistakes and wasted resources.
- Use the environment: Position yourself in areas where you have good visibility and can retreat if needed. Use barricades to create fallback positions.
