The story is inspired by the movie The Island (2005), talking about how people found
out that they are actually clones of real people, so they try to run away from the
island find their own life.

Gameplay mechanism
In my game, there will be two to three players who enter the game at the same time.
Player one plays the role of a citizen trying to escape from the island without being
spotted by the guards, but he/she does not know the right way to escape. Player two
plays as the guard who monitors the CCTV. Once he/she finds someone trying to
escape, they will launch the attack on them. Player three plays the helper guard who
is also monitoring the CCTV, but he/she is trying to help citizens to escape by telling
them the right way to go without being discovered by player two.

Communication
The citizen can talk to the helper guard through certain gadgets in VR which can
connect to the helper guard’s monitor. Through this, they can either talk directly or
use gestures/messages to communicate. The citizen can get information from that,
and the helper guard could guide the citizen to the right way to escape.
Cross-platform
Players use different platforms to play this game. Player one needs to enter the VR
world, while players two and three use AR to participate in the game. Player one will
use the controller to navigate in the virtual world and manipulate the avatar trying to
escape the island. While players two and three participate in the game through AR by
tabbing on the screen or triggering AR content to launch an attack or open the
escape door.
The reason for using cross-platform is because I want to represent two different
worlds through different media (VR and AR). Players who enter the virtual world are
like clones living in clone islands in the movie The Island, living in a fake world and
being monitored and controlled by people in the real world. The reality they believe
only exists in the virtual world, and they may be just the characters or NPCs in a
game whilst players who play the game through the screen or AR are like the doctors
in the movie, monitoring the clones they create. Through programming or just
tapping on the screen, they can change the game world or even decide the lives of
characters in the game world.
