== Terrain ==

Island Interchange features two island states, a high tide, and a low tide.

During the high tide, the map is mostly underwater and only wood can be obtained, all iron sources are underwater and cannot be mined with tools, or exploded with bombs or torpedos. While underwater, iron sources cannot be walked on, tracks cannot be placed on them, and bridges cannot be built on them. The {{Wagon|TurretTower|Turret Wagon}} can shoot iron that is underwater, making it a useful wagon for this biome.

During the low tide, all of the water goes away and players can walk across the entire map on the sand. During low tide, iron sources are exposed for mining. Once an iron source is mined, the tile can be walked on and tracks can be placed.

The tide shifts every 30 seconds and the state is preserved when at the station.

== NPCs ==
=== Crab ===
[[File:Crab.png|frameless|alt=Crab|Crab]]

{{Quote|Can move over water. Rideable and milkable.}}

Crab is a non-hostile {{Icon|BucketMilk|[[milk]]}} [[milk|milkable]] animal that can turn water tiles around it into sand, as well as revealing iron underwater. This allows you to traverse across the water without bridges during the high tide and to gain access to iron, and is especially useful during this biome's boss.

=== Cloud ===
[[File:CloudNPC.png|frameless|alt=Cloud|Cloud]]

{{Quote|Clouds almost always have a cold, and they push items away when they sneeze.}}

Cloud will seek out the tallest item stacks on the ground and actively try to push them into the water. When a stack of items is next to the river, only the item at the top will be pushed into the water.

== Boss Fight ==
=== Octoboss ===
[[File:Octoboss.png|frameless|alt=Octoboss|Octoboss]]

{{Quote|Throws blobs of water with its tentacles and sets the whole map underwater if the tentacles are not destroyed in time.}}

[[File:Octoboss_Level.png|thumb|alt=Octoboss|The Octoboss appearing during the Boss fight]]

The Island Interchange bossfight is the Octoboss. When the boss appears, the entire map is turned into the low tide. The Octoboss will appear along with a number of tentacles what fling water across the map. When a tentacle's projectile hits the map, it will permanently change that location into pure water, even during low tide.

Tentacles can be destroyed by any tool, or by simply placing a bridge on top of it, or by the projectiles of the {{Wagon|TurretTower|Turret Wagon}}. A leveled up turret wagon can destroy all tentacles nearly instantly, making it a great wagon against this boss. Note that dynamites and torpedoes do not damage the tentacles.

If all of Octoboss's tentacles are destroyed before the Octoboss goes underwater, the map remains in low tide. However, if any tentacle remains, the whole map will be converted to high tide until the boss comes back.

Conveyor-Belt-Transporter Wagon

JakoBPyroTech:

[[File:ConveyorBeltWagon.png|link=]]

== Handbook description ==

Offers conveyor belt masts that connect within a certain range to create a portable conveyor belt.

== Strategy ==

The wagon can have 2 or 3 masts. If the masts are within the range of each other, a conveyor belt would be established between them that allows two way transportation.

If the wagon has *exactly* one mast on it, you can connect another mast to it so that it follows the train. The mast on the wagon cannot connect to two masts on the ground at the same time. The connection breaks if the wagon moves out of range. The connection cannot be auto established if the wagon comes in range with a mast at the front.

The conveyor belt can transport everything the player can carry except for animals. Transporting Dynamite will ignite the fuse as soon as you place it on the conveyor belt.

You can only manually place items onto the end of the conveyor belt on the ground. You cannot use throwing or place items in the middle or on the end of the conveyor belt on the wagon. You also cannot throw the masts.

Using the {{Icon|PushToBox}} storage push extension with this wagon is a good idea, as it will automatically send collected resources to the storage wagon. Paired with the {{Icon|Magnet}} magnet extension, resources will be automatically picked up within the range of the mast and be sent to the train, allowing you to transport items to the train at range.

{{Icon|Supercharge}} Supercharge, {{Icon|RangeIncrease}} range extension and {{Icon|StackIncrease}} stack-boost are also good options to fill any remaining extension slots on this wagon.

Stations is where players can rearrange their wagons, purchase new [[Wagons]] or [[Extensions]].
At all stations, except for the [[Biome Junction Station]], there is also a sign post where players can use one bolt to purchase an additional task, and a 3 slot storage space where players can store either wagons or extensions.

== Station Difficulties ==

Each level can be any of 4 difficulties. The first station of a biome is also an easy level. The difficulty of a level is indicated by the icon below the station. The harder the level is, the more bolts are rewarded at the end of the level. In addition, quality of the wagons at the [[Crate Station]] are also related to the difficulty.

Note that the difficulty of the level can be influenced by some [[Cartridges]].

=== Easy ===
[[File:Difficulty_Easy.png|64x64px|link=]]
Rewards {{Bolts|2}}

Easy levels always have a clear path to the station that is not blocked by resources or any pinches forced by the mountains. Rivers blocking the path is usually 1 tile wide.

If the station is a [[Crate Station]], the wagons would often have debuff extensions on it.

=== Medium ===
[[File:Difficulty_Medium.png|64x64px|link=]]
Rewards {{Bolts|3}}

Medium levels have a lot of resources that can block the path to the station. However, there is no pinches and usually does not force players to build long bridges.

=== Hard ===
[[File:Difficulty_Hard.png|64x64px|link=]]
Rewards {{Bolts|4}}

Hard levels have much more mountains and lakes. Resource management is crucial. However, mountains normally do not form pinches.

If the station is a [[Crate Station]], the wagons would often have regular extensions on it.

=== Extreme ===
[[File:Difficulty_Extreme.png|64x64px|link=]]
Rewards {{Bolts|5}}

Extreme levels are extremely rare (unless the [[Cartridges#Cartridges|Nether Cartridge]] is equipped). Resources are even more scarce. At least one pinch is guaranteed per level.
Also note that the station of a extreme level is always the [[Cartridge Vault Station]], unless you have a enough nether cartridges equipped, in which case stations of other types can appear instead of Cartridge Vaults.

== Station Modifiers ==

Some stations may have additional modifiers shown next to the difficulty icon

=== Animals ===
[[File:Modifier_Animals.png|64x64px|link=]]
There would be more animals spawning in the level.

=== Double Bolt ===
[[File:Modifier_Double_Bolt.png|64x64px|link=]]
You can find two bolts hidden in the level

=== Long Map ===
[[File:Modifier_Long_Map.png|64x64px|link=]]
The map of this level is 15m longer than a regular level.

Note: regular levels are 31m long.

=== Sale ===
[[File:Modifier_Sale.png|64x64px|link=]] All items sold at this station is {{Bolts|1}} cheaper.

Upgrade cost also drops by {{Bolts|1-2}} per upgrade (see [[Blacksmith Station]] for details).
Note that since the original price of the extra task only costs {{Bolts|1}}, having this modifier effectively means the additional task is free.

=== Extra Stock ===
[[File:Modifier_Extra_Stock.png|64x64px|link=]] The station has a greater selection.
See the individual station's page for details.
