Strategy

This stage is pretty much the same as the original, since Cerberus Kids are merely glorified peons and Hackey isn't really a threat with its massive blindspot (1200). Bring meatshields to stall melee pushers, anti-Red specialists to cut them down, and additional CC units to keep Red Cyclone in check.

Wave Units might be necessary to neutralize the Cerberus Kids.

Recommended Units

• Courier Cat - Courier's LD attacks deals Massive Damage against Red enemies, decimating them with ease, and is powerful enough to wipe out Cerberus Kids in two hits.
• iCat - iCat's 100% chance to Freeze Red enemies for 2 seconds can halt the buffed Red pushers dead in their tracks (until Capy and Blitzen arrive, at which point they must be supported by other units) to reduce defensive pressure.
• Sanzo - Sanzo's 20% chance to Slow Floating enemies for 4 seconds at midrange makes it useful against Red Cyclone to impede its advance, since it has more range than iCat to avoid enemy midrangers better, and could also be used against Shy Boys at the beginning if necessary.

Lineup (Uberless): Manic Mohawk, Manic Eraser, Maximum the Fighter, Elemental Duelist, Can Can Cat, Courier Cat, iCat, Bullet Train Cat, Roe Cat, Awakened Bahamut.

Cannon: Thunderbolt, for timing A.Baha hits.

Battle: As soon as the level starts, spam your two meatshields. When you can afford it, send out a Bullet Train, then a Can Can. Send out a Roe or two and a Maximum or two, maybe an iCat. Keep spamming your meatshields and replacing the other units as they die, to stall while upgrading your wallet as high as you can. You don't want to push too hard. The Shy Boys will likely die before the St. Pigge, and you should have your wallet at level 6-7, and it should be pretty full by the time the field is clear. Then spam everything on cooldown except for A.Bahamut. When the boss wave starts, wait until you see that the enemy's frontline has started to line up (not sync up with attacks, just be in the same spot), and that your iCats have frozen them. Wait until Hackey's done attacking, then send out A.Baha. Time the thunderbolt cannon to freeze the enemies to ensure that A.Baha gets as many hits as possible. Everything should die in pretty short order, including the base.
