A personal project made with an enthusiastic group of three to run a zombie experience in our office at night. The free event was open to all employees and lasted around 1hr 45mins each round.
The immersive game was a mix of room escape, nerf gun battles, and stealth.
The simple element of stealth in the dark was a significant factor in the game. This taught me how a fully immersive experience can differ from a video game in terms of design. In a real-life design, one can extract so much value from just how many more actions and verbs you have in a real-life experience.
I eventually reused part of this concept to build a much shorter experience, which still used the dark and slow-moving enemies.
