Terrain

Terrain tiles are the basic building block of Before We Leave. Buildings and roads are built on top of one or multiple tiles. Without a road, peeps move at -75% speed. All terrain can become Polluted.

Grass
Grass tiles are the most basic tile. Your starting island will always be made up of grass tiles and highlands under default start settings. Wells and any crop can be built on grass tiles, assuming the island has the corresponding Fertility. Grass is one of the three tiles that can be generated with trees.

Desert
Peeps that walk across desert tiles can become fatigued if they are not clothed, causing them to rest and idle. Wells and crop fields cannot be constructed on desert tiles. Desert is one of the three tiles that can be generated with trees.

Snow
Much like desert tiles, snow tiles cause fatigue as Peeps walk over them without sufficient clothing. Wells and crops can be built on snow tiles, but islands with snow tiles tend to have very limited fertility. Snow is one of the three tiles that can be generated with trees.

Ocean
Ocean tiles come in different styles of varying depths, but they all function identically. Ships can only move across ocean tiles. Islands are separated by large expanses of ocean tiles, but some islands can also posses small archipelagos that are registered as the same overall landmass. Oceans can become polluted but cannot be Cleaned.

Highlands
A higher section of ground where Rusting Hulks, Mountains, Electronics Piles and other raw resources like Ancient Technology deposits are located. Highlands can be accessed by building an Elevator on one side. After researching Laser and unlocking Deep Mines, they will be revealed as either Iron or Stone Highlands and a Deep Mine placed on them will produce the according resource.

Highlands are not to be confused with Mountains; Mountains are where Stone is obtained via a Quarry.

Ice
Ice tiles make up the polar caps of planets. They are completely inaccessible.
