Out of Despair is the sixth stage in Sub-chapter 27, Body and Soul.
At beginning you face a Capy. Then three Capies join and five more will be added after a while.
All you need for this level is 3 spamming cats, and the Crazed Whale Cat and the Island Cat. Build up your Crazed Whale Cats and Island Cats to overthrow the Capies. Make sure your Crazed Whale Cats and Island Cats are protected with the spamming cats.
The alternate strategy is required 5 to 6 $75-class Meatshield (Cat, Boogie Cat, Pumpcat, etc), Crazed Gross, and Cat CPU (power up). Rich Cat (power up) can help, but not necessary. First, turn off your Cat CPU. Then upgrade your wallet to max, while you stall any approaching Capy. Once your wallet is maxed out, turn on Cat CPU and enjoy the view.
