Wrath of Titanium (Deadly) is the first stage in Bitter Irony. Completing this stage for the first time will yield a reward of 1,000,000 XP.
Cat Deploy Cost: Only 750¢ or less
It is an exact copy of Attack on Titanium, albeit with a restriction in place. Due to the restriction, the player can no longer rely on expensive anti-Metal cats such as Catornado or Sakura Sonic, but can still use cheaper ones such as Space Cat.
Use high stamina cats that are immune to knockback before the Metal Hippoe moves out of his base stack them while sending out damage dealers. Immune to knockback is used for Super Metal Hippoe.
Row 1: Rope Jump Cat, Clockwork Cat, Space Cat, Bronze Cat, Hoop Cat
Row 2: Crazed Mohawk, Crazed Tank (Manic versions are even better), Catasaurus, Moneko, and Neneko.
It is possible to beat this level without killing a single enemy. Level up your worker cat to level 4, then sent out 1 Crazed Tank. Level up your worker cat to level 6, then send everything out non-stop. Very easy if you do it fast enough.
Strategy 2: (feat Princess Kaguya)
Lineup: Mohawk cat, Eraser cat, Sunny Neneko, Princess Kaguya, and Crazed Whale. Bottom 5 can be anything. At the beginning, upgrade worker to max. When the Metal Hippoe comes close to your base, spam crazed whale, eraser, and Kaguya. When SMH cames, spawn Sunny Neneko. Keep spamming eraser, Kaguya, crazed whale and Sunny Neneko and it will be fine.
Strategy 3: (feat CHEESING intense)
Lineup: Row 1- Green Thumb CatCombo, Bony Bone CatCombo, Pulling Strings CatCombo
Row 2- Eraser (20+16), Crazed Tank (14), a high dps attacker, Michelangelo (16), Puppetmaster (16)
(those metal buffer are optional if you have Riceball Cat, Ramen full talent or Zamboney Cat)
Item(s): Speed Up (really useful) (you don't have to bring Rich Cat and Cat CPU, that waste your money)
(cheese like the expert stage and you will have 1,000,000 XP for free)
