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. Become a lone post-apocalyptic survivor and face wave after wave of zombies, growing more intense each day! The game combines zombie shooting and defense mechanics, requiring strategic thinking and quick reflexes to survive as long as possible.

Use different weapons, such as firearms and melee, and set traps to stay safe from those dangerous zombies. Eliminate them and progress through even more intense zombie waves in the upcoming days. If your character dies, you have to start from the very beginning, since there are no checkpoints. 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.

How to Play Undead Invasion

The core gameplay loop involves fighting incoming waves, using and placing defenses, and upgrading between days. 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.

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. 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.

Note: The game includes gory effects, which may not be suitable for younger audiences or those who find such content uncomfortable.

How to Master Undead Invasion

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.

Maintain distance whenever possible and use ranged weapons to thin out zombie hordes before they reach you. Switch between weapons based on the situation - use shotguns for close-range groups and rifles for distant targets.

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 at chokepoints where zombies are forced to converge, maximizing their effectiveness.

Create layered defenses with multiple barricades and traps to slow down fast-moving zombies and give yourself time to eliminate them before they break through.

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 that will help you survive the next wave rather than saving for expensive items.

Balance your spending between offensive capabilities (weapons) and defensive tools (barricades, traps). Health items are essential for surviving longer, so always keep some coins reserved for emergency healing.

Master Weapon Selection

Different weapons serve different purposes. Pistols are affordable and easy to upgrade for early stages. Shotguns deliver powerful area damage at close range. SMGs provide high rate of fire for crowd control. Rifles offer stable, powerful shots for long waves. Bazookas can eliminate entire hordes but use them wisely.

Always keep a melee weapon ready as a backup when ammunition runs low or zombies get too close. The knife can be a lifesaver in dangerous situations.
