I, I can't win...

The zombie stage in Filibuster is really troublesome, isn't it? The key to clearing it is to prioritize characters with the Zombie Killer skill to prevent revivals. Don't give up, you can do it!

Ah, the trauma stage. I struggled with this for 4 months. This stage was all about whether I could defeat the zombies with White Luna, right? (Zomki)

I think Reika and Blizzardena are pretty strong. You can make it easier by using characters with Angel Cannon or knockback abilities (like Vol Bombers) to prevent zombies from getting through.

At the start, do nothing and let the Angel Dog bite the castle, then deploy Kankan. Once you collect the money, hold the entire front line until the Daffunded arrives, then commit all anti-zombie firepower. After defeating it, you'll only have the Filibuster and Andromeda left, so focus on anti-alien units to win.
