#REDIRECT [[Room Control Level]]
RCL, short for Room Control Level, is describes the level of any owned room. It determines how much can be done in a room, and ultimately how useful it will be to the player.
 
 
== Increasing RCL ==
 
 
A room's level can be increased by <code>upgrade</code>ing its [[StructureController|controller]] using a creep with a work [[Parts|part]] carrying energy. The energy used will be added to the RCL at a 1:1 ratio by default. This ratio can be improved by applying any [[Boost|boost]] of the GH category to the creep's work [[Parts|parts]].
 
The resulting amount of points added to the room's control level is automatically added to the player's [[GCL|GCL]] as well.
 
 
== Levels ==
 
 
After claiming a room (or spawning in) it starts out at level 1 and can be raised up to level 8. The higher the level, the more [[Structure|structures]] can be built.
 
The full list of structures available to each RCL is available at the official docs for [https://docs.screeps.com/control.html#Available-structures-per-RCL Control]].
 
In the following a short list of notable structures per level. Note that many structures are not available to their full capacity from when they're first introduced. Many of them will give you a certain amount to be able to be built and add more every or every other level. One exception are ramparts, which dont have their numbers, but their <code>maxHits</code> increased instead.
 
 
=== Level 0 ===
 
 
[[StructureRoad|Roads]] and (up to 5) [[StructureContainer|containers]] can be built in any room, regardless of a presence or absence of a controller.
 
 
=== Level 1 ===
 
 
The most notable (and only new) structure at level 1 is the [[StructureSpawn|Spawn]], which enables a room to be self-sufficient as it can now spawn its own creeps.
 
 
=== Level 2 ===
 
 
Level 2 adds [[StructureRampart|ramparts]] and [[StructureExtension|extensions]]. The former is good for safety purposes, but the latter is what helps with progressing faster.
 
 
=== Level 3 ===
 
 
RCL 3 is regarded as one of the "milestones", as it adds the first [[StructureTower|tower]], giving the player access to passive defense that is easily implemented code-wise.
 
 
=== Level 4 ===
 
 
At level 4 the [[StructureStorage|storage]] can be built, which enables the player to manage their energy (and potentially other resources) more effectively, as they now have a much bigger buffer.
 
 
=== Level 5 ===
 
 
Level 5 adds the first [[StructureLink|links]], which are immensely useful for increasing a room's efficiency as they remove the need for haulers between the positions they're built in. This way spawn availability is freed up and energy for spawning said haulers is saved.
 
 
=== Level 6 ===
 
 
With RCL 6 the room has access to the [[StructureTerminal|terminal]], which enables market activities and market-independent inter-room transfers across the whole shard.
 
In addition to that the room can now build [[StructureLab|labs]] and the [[StructureExtractor|extractor]], which are important for getting economic access to [[Boost|boosts]].
 
 
=== Level 7 ===
 
 
Level 7 gives access to the [[StructureFactory|factory]], which is used for either compressing resources or creating [[Commodities|commodities]] to be traded for [[Credits|credits]].
 
A second Spawn is available now, effectively doubling spawn speed, and Extensions' capacity also gets doubled, enabling spawning of much larger creeps than before.
 
 
=== Level 8 ===
 
 
This is the highest level a room can reach and gives access to the [[StructureNuker|Nuker]] and the [[StructurePowerSpawn|Power Spawn]].
 
With the last Spawn and another doubling of Extension capacity spawn speed and available creep size are increased again.
