Acts of Cat-God (Insane) is a Continuation Stage the player can try whenever they beat Explosion in the Sky. When completed for the first time, it will give an Epic Catfruit. Any further successful clears will yield Cat CPUs.
The battle starts with 2 Heavenly Hippoes. Shortly thereafter, an Angelic Gory appears, with Gabriels spawned. When the enemy base is hit, Sunfish Jones and Divine Cyclone spawn. After that, Gabriels will spawn at a mild rate.
Since the previous stage only required 3-4 cats (including Awakened Bahamut Cat), the rest of the slots can be used for this stage. Just bring 3 meatshields (preferably including Artist Cat/Ramen Cat) and 2 freezers (Momotaro and Princess Juliet Cat/Juliet the Maiko are perfect, if you use A Gift of Cats, you'll have to clear the peons first), and the rest for damage dealers (anyone with 250+ range). A possible lineup would be Crazed Macho Cat, Crazed Wall Cat, Artist Cat/Ramen Cat, Awakened Bahamut Cat, Momotaro, Princess Juliet Cat/Juliet the Maiko, King Gamereon and Dark Catman (the latter two can be replaced by Paris Cat/Dragon Cat), and Sanzo Cat and Cameraman Cat (only for previous stage).
Just stall the first peons with meatshields and start stacking Juliet and Momotaro (If you only have A Gift of Cats, just stall them because GoC is single-target. Spawn 1 or 2 until the peons are handled, then start stacking). Upgrade the Worker Cat to level 3 or 5. When you have enough money, continue the push towards the enemy base to let Divine Cyclone come out. Let it advance at least 1/4 or 1/3 of the stage until Sunfish Jones spawns. This way Sunfish Jones will only hit your meatshields while the freezers are safe behind them. The long-ranged attackers will kill the perma-frozen Divine Cyclone. Sunfish Jones is easy after that as the enemy base has low HP.
A possible lineup under this strategy:
Row 2: Crazed Macho Cat (20), Crazed Wall Cat (20), Ramen Cat (46), Cyborg Cat (48), Sanzo Cat (31)
Strategy 2 (Talented Sanzo)
Row 2: Awakened Bahamut Cat, any other 4 decent Area Attackers, especially those that are good against Angel Enemies (Glorious Amaterasu, Dark Merchant Babil, Cyberpunk Cat and Eva Unit-02, Code 777 are examples)
Sanzo Cat has a Talent to gain the ability to slow Angels. This makes Acts of Cat-God a bit of a joke, as it enables your other cats to deal with Divine Cyclone as they would with any other one of them. Bring a set of cats that can deal with the Gabriels that will rush out with the Cyclone when you hit the base, then the fight is pretty easy. Your Sanzo Cats should permanently slow the Cyclone, giving your offensive units plenty of time to deal with it. Once the Cyclone dies, send out an Awakened Bahamut Cat to deal with the Sunfish Jones. After the Sunfish is either dead or behind the enemy base, you should be able to destroy the base and victory is yours!
