Attack on Titanium is the 5th Cyclone Stage. It appears every Sunday.
Upon completion, players have a 30% chance to unlock Hoop Cat.
Battleground
The first enemy to appear is a Metal Hippoe, which appears after 101.5 seconds. After 134 seconds, a Super Metal Hippoe will appear.
Once 184 seconds have passed, Metal One Horn appears. A Sir Metal Seal appears after 216 seconds.
The boss, Metal Cyclone, will appear when the enemy base's HP is down to 90%.
During the boss fight, these enemies will appear in the following pattern: Metal Hippoe -> Super Metal Hippoe -> Metal One Horn -> Sir Metal Seal -> Super Metal Hippoe After that, every ~70 seconds, 1 Super Metal Hippoe will be spawned.
The cyclone stages previous to this are key to beating this stage: they give you anti-metal cats that are vital to success here.
Strategies
Strategy 1
The use of Critical Hitters is almost mandatory in this stage.
Use Samba Cat, Macho Cat and Crazed Macho Cat as meatshields. If you have Uber Rares that can perform Critical Hits such as Tesalan Pasalan, use them along with Cats that can knock back Metal enemies.
Tesalan Pasalan and Berserker Cat are probably the best cats for this stage. Tesalan Pasalan has very long range, and enough power to OHKO Metal Cyclone, and his True Form Lufalan Pasalan has an even greater chance to do a Critical Hit. Berserker Cat has area attack and a high Critical chance. Use Tecoluga to OHKO the Cyclone, and use Berserker to kill the other Metal enemies.
Hayabusa's first form has Area Attack, quickly gets to the front line, a 30% chance to perform a Critical Hit, and has long distance. Mighty Lord Gao is very useful as well, killing Metal Cyclone in one hit if it does a Critical Hit.
Strategy 1.5 (Only Tesalan)
Tesalan Pasalan at level 15 or higher is all you need for this strategy.
Just spawn Tesalan. Let Tesalan hit the base. This will cause the cyclone to spawn and Tesalan Pasalan can instantly kill the cyclone with a single critical hit. This strategy may require multiple attempts if your RNG fails.
Strategy 2 (Cheese)
The goal is to exploit the "max number of enemies"
Line up one or two meatshields (Crazed Tank/Tank), high damage or high DPS (fast attack rate optional) Cats (Bahamut, Takeda Shingen, Crazed UFO, Paris, Raiden, Balrog), and Metal knockback cats (Bronze/Michelangelo). Shinji Cat (Evangelion Col) is extremely useful if you have it.
After ~1 min 39 seconds, the first Hippoe will spawn. Start "spamming" Michelangelo Cats between 1 min 30-35 seconds into the battle, and summon maybe one or two tanks to keep them alive.
After ~2 min 10 seconds into the game, Super Metal Hippoe will spawn. Start spamming all your damage cats about 2 min into the game (Tank Cats too). Hopefully by this time, both Hippoes will have been knocked back to behind the base. Now they'll be "invincible" and the enemy base will be free for you to attack without having to worry about the Metal Cyclone.
Note that Riceball Cat will help here as it will stop the Super Metal Hippoe from pushing back the meatshields.
Note that Super Metal Hippoe outranges Bronze/Michelangelo cat, so you have to keep them protected with units with high health such as Jamiera and Crazed M. Titan. LD units that can snipe the base can also come in handy( I used Nobilan Pasalan, but likely megaphrodite/catman can also work).
Strategy 3
Lineup: Mohawk Cat, Crazed Macho, Crazed Tank, Pair Rope, Puppet-Master, Miss Moneko/Miss Neneko, Space Cat, Michelangelo, Crazed Whale and Island.
Beware that Crazed Whale and Island are slightly expensive which makes them less talented.
Start off by waiting and maxing the Worker Cat You should have a level max worker and around 8,000¢ when the first Metal Hippoe comes out. Feed him with 1 to 2 Rope Jump. Metal Hippoe should be killed before Super Metal Hippoe (SMH) comes. Let SMH proceed to your base. Start stalling SMH using only meatshields and Space Cat. Then Metal One Horn will come in. Spawn in Puppetmaster and Rope Jump. Once everything is killed, Sir Metal Seal (SMS) will appear about the time. The player needs to kill it before hitting the base.
Start off by waiting because SMS must die before Metal Cyclone is spawned. SMS and the Cyclone make the stage almost Once you have killed SMS, only Super Metal Hippoe will come afterwards which is easier. Because at that point of time, the player will have plenty of Space Cats stacked up. They can kill SMH with 3 crits, but it takes them so many Critical Hits to kill Sir Metal Seal.
After SMS is slain, the player can spam everything. Throughout the entire level, one should be wary about the Whale/Island Cats. They are fairly pricey, so they can potentially drain the wallet of a beginning player.
Strategy 4 (Lack of anti-metals)
Cat lineup: Mohawk cat (31), Gato Amigo (30), Crazed Tank (30), Moneko (20), Neneko (16), Crazed Cat (1), Catasaurus (31), Clockwork Cat (1)
Yeah that's right, some cats used are level 1. The level is not as hard as it seems, here is some advice.
- Don't hesitate to use low-level cats if you need extra meatshields, as the Metal Cyclone kills anything instantly anyway.
- Don't try your luck with fast-attacking cats like Lumbercat or Giraffe, as the Cyclone has too much health.
- If you have the four meatshields that I used or better ones, Tank Cat can be a waste of money because it's slow, more expensive and still dies instantly.
- If you don't have stuff that knocks back or freezes Metals, "slow" can be of great help, even if the cat isn't upgraded.
- You need the Cat CPU and a good amount of luck.
Try it even if you're not sure you can do it! You might get surprised!
