Gameplay

TOKYO WALLED CITY follows the classic immersive sim principle: situations should not be resolved through direct combat alone. Reiko can hack cameras, shoot out lights, crawl through air vents, peek around corners, use rooftops and take out enemies from above.

The stealth system takes visibility and noise propagation into account. The toolkit includes silenced pistols, blades, improvised gadgets, high-tech traps and grappling tools. Enemies range from gangs and augmented fighters to menacing androids.

The first Early Access version is set to initially include a fully developed area with the core stealth, survival and combat systems.
