In this invasion, it's recommended to use as many mutations as possible. A Mutant Monolith can really help you out if you go for Combined Zombies with all available mutations. Use some Headless type first as tanks, send some Garden type after groups of zombies, and the rest can be Regular + Female type or Large + Small type. When 15 seconds have passed, a giant McDonnell Robot will appear in the backgound. It is crucial to Rapidly tap his eyes (12 times) until he goes away -about 5 seconds. Otherwise, he will one-shot kill a bunch of your zombies with his nuclear flame shooting eyes. When about 90 seconds are left on the timer he will start moving, making it even harder to hit his eyes. He cannot be destroyed, and you can only send him to rest a bit by tapping. A possible order is 2 party zombies,7 zombarians,2 robo zombies,3 zombees,1 zomielocks,and 1 imp zombie.
The other three robots will always be the same, just in a random order. Everyone of them has a special ability:
Junkbot can summon Junk Walls, they are similar as the Ninja's Carrot Wall. Brobot's throwing speed is faster than the others, making himself a threat to garden type zombies. Brainbot can push back your zombies with his mind, so if your zombies weren't hungry, you might find yourself in a Do or Die at the end. Tricks against Brainbot's telekinesis:
- It won't push back any kind of headless zombies
- ZomBrutes or Zombarians, when they are using their Bash / Smash ability
- ZomGoblins or Imp Zombies when they are about to explode (Explode / Explode Ver.2 ability).
If an invasion fails, the boss of the robots will say:
- error 404 zombies not found
- PC LOAD LETTER
- Domo Arigato
