Revenge of Carnage (Merciless) is the second stage in River Acheron. When clearing this stage, the player is guaranteed to unlock the True Form of Express Cat, Bullet Train Cat. This is a No Continues stage.
Battleground[]
- 2 Znaches spawn after 3.33 seconds100f, delay 3.33~5 seconds100f~150f.
- 4 Ginger Snaches spawn after 6.67 seconds200f, delay 6.67~8 seconds200f~240f.
- When the base reaches 99% HP:
Strategy[]
The map is noticeably shorter than Realm of Carnage, which exacerbates any mistakes related to the burrowing patterns of Zombies.
A functional strategy is to equip a hard-hitting Zombie Killer, dual Islands, Roe Cat, dual Erasers, Ectoweight Cat and Housewife Cat. All there really is to do is spam both of your Islands and your main Zombie Killer. If you are lucky enough to have Sarukani, the Strong Up and Defense Buffs used for the dual Islands make Sarukani able to deal with the Zombie threat by themselves, turning the level into a cakewalk.
Also, if you have a tanky Uber Rare like Cat Machine Mk 3, you can use it to stall Hannya to prevent her from attacking your other units while protecting your base from the Zombies since they burrow earlier.
This stage just so happens to have a decently high amount of cheese strats, including one of the strategies listed below. Other strategies include a variant of the aformentioned strategy with Healer Cat CC, or using Warlock and Pierre to melt the base to 0 HP.
If you happen to have Pai-Pai, consider the stage won. As long as you time Awakened Bahamut to hit the first Zroco upon base hit, Pai Pai will quickly melt the boss.
Strategy 1 (Uberless)[]
- Only use the cats in row 2, who must ideally be level 30~40. Zamboney can be replaced by a good anti-Zombie Uber or something to damage Hannya while nothing is in front of her.
- It's also possible without Housewife, if you are very unlucky or want to do it no-gacha for some reason, but she still makes things faster by sometimes killing Zombies in place of Islands, so she's worth having. Using some other Zombie Killer Cats can also really help.
Lineup: Lion King, Seasons of Love, Three Kings, Zamboney Cat, Manic Island Cat, Island Cat, Li'l Flying Cat, Housewife Cat
Cannon: Holy Blast
Notes:
- Only use the cats in row 2, who must ideally be level 30~40. Zamboney can be replaced by a good anti-Zombie Uber or something to damage Hannya while nothing is in front of her.
- It's also possible without Housewife, if you are very unlucky or want to do it no-gacha for some reason, but she still makes things faster by sometimes killing Zombies in place of Islands, so she's worth having. Using some other Zombie Killer Cats can also really help.
Battle: Start with a single Manic Island (level used was 40, but higher is recommended), then upgrade the Worker Cat to level 2 or 3; after that, start spamming Manic Islands and Zamboneys and never stop for the rest of the fight.
Once Hannya appears, the real battle starts. From now on, spam the other units based on the following: Island Cat only when you have a lot of money, Li'l Flying when a Zombie wave appears and Housewife shortly after you start with Li'l Flying. You should always end up with a group of Islands keeping Hannya at bay while another army that includes the two Zombie Killers takes care of the Zombies, with the eventual help of the Cat Cannon.
It shouldn't take a lot; with all those Combos, your stronger units will decimate the stage, even with no items or Ubers in use.
Strategy 2 (Uberless)[]
Level 38
Level 20+60
Level 28+5
Level 31+6
Level 29+9
Level 36
Level 30
- Manic Island, Island, Doctor, Wrestling and Fishman are a part of their Combos.
Lineup: Cap'n Ahab, Moby Dick, Sportswoman, Manic Island Cat 38, Island Cat 20+60, Roe Cat 28+5, Can Can Cat 31+6, Seafarer Cat 29+9, Maglev Cat 36, Awakened Bahamut Cat 30
Cannon: Breakerblast
Items: Rich Cat
Notes:
- Manic Island, Island, Doctor, Wrestling and Fishman are a part of their Combos.
When starting the battle, wait for the Ginger Snaches to come near the base and stall with Roes and anything you need to keep them at bay, but try not to kill them yet. Once the Znaches arrive, send out both Islands. After killing the Znaches and Ginger Snaches, spam Manic Islands, Roes, Can Cans and Seafarers, making sure never to stop spamming those 4 units.
Use Maglev for damage control on the Zeal and Zigges; focus on the Zeal first. Awakened Bahamut can also be used for damage control and even damage towards Hannya if timed correctly.
Strategy 3 (Cheese)[]
- Ideally, iCat should have some investment into the Move Speed Up Talent (Speed Up (M) + (Sm) Cat Combos together such as Spinners + Enter The Ninja will work as a replacement if you don't have the NP), and all Cats should be at as high of a level as possible.
Lineup: Rawhide, Put On Ice, iCat, Eraser Cat, Manic Eraser Cat, Manic Lion Cat, Awakened Bahamut Cat
Notes:
- Ideally, iCat should have some investment into the Move Speed Up Talent (Speed Up (M) + (Sm) Cat Combos together such as Spinners + Enter The Ninja will work as a replacement if you don't have the NP), and all Cats should be at as high of a level as possible.
Start by waiting for the Ginger Snaches to reach your base. As soon as the first one damages it, spawn iCat to hit him twice, and use Dual Erasers and Zamboney to stack until all of them are dead.
Once the Ginger Snaches and Znaches are defeated, stop deploying Erasers and wait. Once the iCats reach around halfway to the enemy base, spawn a single Manic Lion, followed by Awakened Bahamut after a brief pause. Fire the Cat Cannon a moment before he hits the base.
If you timed it right, Awakened Bahamut should hit the Zroco, all the Zombies will burrow, and the iCat stack should permafreeze Hannya. Your goal now is to spawn all of your Combo units to keep the Zir Zeals and Zigges away from your base while Awakened Bahamut makes quick work of Hannya.
The timing of this strategy is pretty restrictive, so if you're failing to time it correctly or Hannya keeps killing your stack, consider using Maglev Cat to snipe the Zroco during the boss wave instead, or adjust your timing to allow the iCats to approach a little more. Enjoy your new Bullet Train Cat!
