Strategy[]
This is a fairly simple yet challenging level; the best way to win is by not using meatshields at all but instead fight with only ranged attackers so a Crazed Gross doesn't hit a meatshield and trigger a Wave Attack. If the player possesses a wave blocker such as Octopus Cat, it can pretty much nullify the stage totally and utterly.
If you have Awakened Bahamut, this stage becomes a joke, as he'll endlessly knockback the Crazed Gross Cats before they can attack. This is obviously not an option until after Into the Future Chapter 3 is beaten.
Strategy 1[]
Level 20
Level 20
- The open slots can be used for Cat Combos, ranged units like Crazed Dragon Cat, and Uber Rares.
Lineup: Macho Leg Cat, Paris Cat, King Dragon Cat, True Valkyrie Cat 20, Crazed Bahamut Cat 20
Notes:
- The open slots can be used for Cat Combos, ranged units like Crazed Dragon Cat, and Uber Rares.
Start by saving money, and when the first Crazed Gross Cat is halfway to the base, spawn Macho Leg, Paris Cat, and Dragon Cat. Spawn Bahamut Cat when you have enough money. The main method for this strategy is to build up an army of King Dragon Cats and Paris Cats and hope to not get hit by waves too often.
Do not let the Crazed Gross Cats stack or get too close to your base as their waves will keep knocking your attackers behind your base and make them useless without proper timing.
Strategy 2 (Wave Shield)[]
Level 20
Level 20
- 1 slot is dedicated to a Wave Shield, such as Octopus Cat
- Any meatshield will do as long as it is within 75¢-150¢,
- Feel free to also use Anti-Traitless Ubers.
Lineup: Cat, Boogie Cat, Catburger, Octopus Cat, Paris Cat, Dragon Cat, True Valkyrie Cat 20, Crazed Bahamut Cat 20
Notes:
- 1 slot is dedicated to a Wave Shield, such as Octopus Cat
- Any meatshield will do as long as it is within 75¢-150¢,
- Feel free to also use Anti-Traitless Ubers.
The player does not need any high level Cats for this strategy except for a wave blocker.
If you have a Wave Shield such as Octopus Cat or Cat Machine, the level becomes a joke as the Crazed Gross Cats have extremely low range, so just summon the Cat with many meatshields, some attackers and fight as you would do in a regular level. Any lineup with a Wave Shield and 3-4 75¢ meatshield will work. The best strategy would be to have several Octopus Cats and many 75¢ meatshields in the front while cats such as the ones mentioned above stack up in the back.
Strategy 3 (Cyborg Cat)[]
Level 28
- Castaway Cat can be swapped out for other midrangers.
- The open slots can be used for Cat Combos (this strategy was tested using Sister Act), and other midrange attackers.
Lineup: Cyborg Cat, Castaway Cat 28
Items: Rich Cat
Notes:
- Castaway Cat can be swapped out for other midrangers.
- The open slots can be used for Cat Combos (this strategy was tested using Sister Act), and other midrange attackers.
Do not send out any cats other than your Cyborg and your other attacker
Immediately begin spamming Cyborgs. You can begin spamming your attacker once you get a surplus of money. Eventually your Cyborgs should build up a stack large enough to knockback the Crazed Grosses with them only landing 1 attack. Once you reach this point and kill the first 9 Crazed Grosses, you have basically already beaten the stage because the enemies will not be able to push nearly hard enough. Remember to use your cat cannon to help clear the peons and buy a little more time to knockback a Crazed Gross.
