The Mansion

The Mansion - PvP Asymmetrical Console Game

Time: Sep 2023 - Dec 2023
Roles: Game Designer, Programmer, Producer
Tools: Unity

“The Mansion” is a two-player asymmetrical PvP game, developed by a five-person cross-disciplinary team over a semester.

This experience immerses players in a haunted ancient Chinese mansion, where one player takes on the role of a young girl in an action-adventure quest to recover her deceased grandmother's memory pieces. The other player controls a ghost leader, strategically commanding spirits to prevent the girl from escaping.

Built in two-week sprints, the game features distinct control schemes (controller for the girl, mouse/keyboard for the ghost) and emphasizes contrasting gameplay experiences.

Main Contribution:

Level & Narrative Design: Designed the mansion level layout and puzzle flow, incorporating Chinese architecture and folklore-inspired monster encounters. Wrote the overarching story and objectives, enriching gameplay with emotional stakes and traditional themes.

Gameplay Programming: Implemented core player and enemy action states (attack, dodge, death, hurt, idle) using C# in Unity. Built locomotion systems for both third-person and god-view perspectives, managing character speed, force, and navigation. Developed gameplay modifiers for animation, hitbox/hurtbox detection, stamina, and invincibility mechanics.

System Architecture: Created robust systems for combat state machines, enemy AI, player tracking, and status management. Developed UI systems including health/stamina displays, menus, and input-based UI alignment.

Production & Prototyping: Led integration of design, programming, audio, and art assets across platforms. Rapidly prototyped and iterated level and gameplay systems using team feedback and testing.

Character/ Narrative Design

One player embodies a determined young girl on an action-adventure quest to retrieve her deceased grandmother's lost memories – represented by three key objects hidden within the estate.

The other player takes on the role of a malevolent ghost leader, employing strategic thinking to command a legion of spirits and prevent the girl from succeeding.
