DARK CRYSTUM (AppID: 3978500)

You play as a weak engineer girl, abandoned in the overgrown wilderness of a desolate human city. Wandering in desolation and helplessness, enduring hunger and experiencing loss and despair, she inadvertently obtains a controllable, initially shattered old-fashioned pilotable robot. Through scavenging and modifications, she struggles to survive in this monster-infested environment, gradually uncovering the mastermind and conspiracy behind all these pervasive mutations.

· Pilot your mech to battle among the abandoned city buildings. Every structure and object in the environment can be destroyed. The city, ravaged by monsters, is left as a broken ruin, emphasizing the devastation and helplessness brought by war.

· Your war mech possesses powerful upgrade capabilities and attack methods. Amid constant monster assaults, you can collect airdropped supplies to enhance your attributes and skills, continuously growing stronger.

· Players can exit their piloted mech to search for supplies and parts in the dark and dangerous city outside the cockpit, used to modify and upgrade their armor.

· The game can be played entirely with just a computer mouse. All operations are handled through mouse clicks, long presses, double-clicks, and mechanics triggered by different timing during gameplay to activate various skills. This results in minimal UI screen occupancy, allowing players to fully and easily enjoy the game's visual presentation and gameplay experience.
