We are announcing KAIJECT, a meditative first-person action game about fighting giant kaiju from within.
KAIJECT в Steam

Players will land on the bodies of massive creatures, drill their way inside, carve their own paths through living structures, and reach the main organs to stop the monsters and save the city.

Inside the kaiju, players will find resources, hazards, hostile creatures, and points of interest to explore. During each mission, they can upgrade their weapons and gear, unlock new paths, and change the behavior of the living environment by destroying the monster’s organs.
