The Island is as much a tech demo as it is a short game. To allow for maximum flexibility, I opted to create my own terrain system rather than using Unity's in-built terrain. The terrain is therefore made of individual tiles created from meshes generated at runtime.

To enable the game to be performant I developed a chunking system, so only the parts of the world currently visible to the player are active.

Finally, I created a system to allow a storm to arrive dynamically, ramping up in intensity from a light drizzle to heavy rain, wind and lightning.
