- At the start of the battle, a Metal One Horn will spawn with 2 more that follow after 6.7 seconds and 10 seconds.
- After 16.7 seconds, the boss, Daboo of the Dead, will spawn.
- After 30 seconds, 5 Metal Doges will spawn, delay 5~10 seconds.
- After 80 seconds, 5 more Metal Doges will spawn, delay 10~20 seconds.
- After 100 seconds, 2 Super Metal Hippoes will spawn, delay 3.3 seconds.
- After 183.3 seconds, the main threat, 1 Sir Metal Seal, will spawn.
The key to success here is killing the metal seal; do that while your base isn't about to be destroyed and you basically win. As for Daboo, dealing damage to him can wait, so any damage dealt before only serves to knock him back.
High level Noodle Cat and Modern Cat are great meatshields, while 2 Soba Cats can take away most of SMS's hp.
sniper, rich cat and an accounting combo are recommended, as well as the holy blast.
