Kaiju Alpha Gameplay and Strategy
The game changes often. Update 53 added Godzilla In Hell, remade Biollante and fixed the Skeleton Godzilla 1954 quest. It also raised the health of several monsters.
| Kaiju |
Base HP |
Max HP |
| Titanus kaiju |
5,000 to 5,300 |
5,800 to 6,400 |
| Male MUTO |
3,200 to 3,500 |
3,975 to 4,300 |

4,980 to 5,300 |
| Queen MUTO |
4,625 to 4,800 |
5,655 to 5,900 |
Every MUTO also got extra skill damage. Godzilla 2000 went the other way: its fifth skill does a little less damage and takes longer to come back.
