Undead Invasion is a game that combines shooting, tower defense, and roguelike elements! Fight for survival, build fortifications, and adapt to increasingly fierce waves of zombies. How long can you survive?
In Undead Invasion, a fragile wall and a single bullet divide life and death. To not only survive but thrive, you need more than just fighting instincts. This article will be a comprehensive guide, leading you step-by-step to mastering every aspect of the game.
Success in Undead Invasion is built on a clear tactical loop. Understanding this is the first key.
Repair & Reinforce: Always prioritize repairing damage to your fortifications first. A solid wall is more important than a new weapon.
Smart Shopping: Spend your points strategically. Analyze the last wave: Did it lack area-of-effect damage? Consider shotguns or mines. Overwhelmed by zombies from a distance? A rifle is a good option.
Plan your positions: Use this time to rearrange traps and obstacles, creating "choke points" to guide and eliminate zombies more effectively.
Prioritize targets: Always target specific zombies (shields, vomit, large size) first. They can quickly disrupt your tactics.
Manage distance: Use Spacebar to maintain a safe distance. This is a free and invaluable tool for escaping or buying reload time.
Flexible weapon switching: Don't rely on just one gun. Use long-range weapons to handle threats from a distance, and quickly switch to melee weapons or shotguns when at close range.
Take Full Advantage of Playground Mode: This serves as your secure testing ground. Spend time here experimenting with all kinds of weapon combinations, traps, and defensive layouts without taking any risks. Find the strategy that best suits your style before applying it to real combat.
Manage Resources, Don't Just Attack: Don't blindly buy the most powerful weapons. Sometimes, a stronger wall or better armor (like the Juggernaut or Hazmat Suit) will keep you alive longer than an expensive gun.
Don't Underestimate Melee Weapons: As experts have pointed out, the Marasuma Blade or Great Sword, can be a lifesaver when you're out of ammo or surrounded. Get familiar with at least one powerful melee weapon.

For Shield Walkers zombies, avoid direct attacks. Use armor-piercing weapons like heavy machine guns, or cleverly throw grenades/artillery behind them. The most effective way is to use a sniper rifle to accurately shoot the unshielded head from a safe distance.
For vomit zombies (Vomit Walkers), prioritize eliminating them from a distance before they get close enough to attack. Investing in protective gear (Hazmat Suit or Juggernaut Suit) will significantly reduce poison damage and increase your chances of survival.
There is no single "strongest" weapon; it depends on the situation and play style. The Marasuma Blade (Japanese Sword) is strong in close combat and dealing with crowds at extremely close range. Its strength lies in its ability to slash through multiple targets in one go, perfect for escaping when surrounded. The Minigun, on the other hand, is strong in its overwhelming firepower from a distance, ideal for blocking an entrance and preventing zombies from approaching from the start.
Playground is a unique and extremely useful feature. It's a safe testing mode where you can experiment with all weapons and traps without wasting resources. Practicing in Playground will save you many points and increase your survival rate in real gameplay.
Focus on upgrades. Instead of constantly switching weapons, invest in upgrading the damage, attack speed, or ammo capacity of your most proficient basic weapon (like a shotgun or rifle). Use points to buy and upgrade traps (Claymore, Spike Barrier). Building a solid defensive maze is far more important than relying solely on guns. Finally, avoiding being cornered is key to survival.
Undead Invasion is an incredibly fun zombie shooting game. It's a symphony of tension, where every decision about building, spending, and fighting resonates with the outcome. By mastering the survival loop, understanding each tool at hand, and learning from failures, you'll not only protect the orphanage but also write your own memorable survival story.
