View source for Explorable Ruins

In [[Season 4]], a new type of {{MetaInline|Ruins}} was introduced, the {{MetaInline|Explorable Ruins}}. There are three: [[Abandoned Hotel]], [[Abandoned Hospital]], and [[Abandoned Bunker]]. These special ruins allow {{MetaInline|Citizen|displayname=Citizens}} to explore and search the interiors through various corridors connecting the [[File:small_exit.gif|top|link=World Beyond]] [[World Beyond|Entrance]] to various dead ends and long abandoned rooms.

Explorable ruins are always unburied.

It takes 1 {{AP}} to enter the ruin. You cannot enter the ruin either if you are {{MetaInline|Wounded}}, {{MetaInline|Terrorised}} or turning {{MetaInline|Escorting|displayname=Escort mode}} on, or {{MetaInline|Escorting}} someone. You will also need to have {{MetaInline|Control Points|displayname=Control}} of the zone, unless you are a {{MetaInline|Scout}} with the camouflage on, then no zone control is required.

You can only enter the same ruin once per day. You cannot enter if someone else is exploring inside. 

If you enter while someone else is exploring inside, you will see the following message:
: ''You cannot enter this building ...''
: - - - -
: ''there isn't enough oxygen for more than one person!''

'''Bug''': You still receive this message if you try to enter when you have escort mode on.

== Exploration ==
[[File:Ruins_interface.JPG|300px|thumb|right|The interface while exploring.]]
The image to the right shows the interface while exploring an [[Abandoned Bunker]]. The top right corner shows the amount of oxygen left, the three arrows show possible directions to go, the center shows the player, and to the left of the player is the remains of a killed zombie.

You start with 100% {{O2}}. It depletes at a rate of 1% per 3 seconds. {{MetaInline|Scavenger|displayname=Scavengers}} start with 150% {{O2}}. This equates to 5 minutes for non-Scavengers and 7.5 minutes for Scavengers. You must get back out before your {{O2}} runs out. If you fail to do so, you will be forced out, obtaining a random {{MetaInline|Wounded|displayname=Injury}}. All items in your {{MetaInline|Inventory}} will be dropped within the ruin at the last zone you were in.

You may encounter zombies inside the ruin. [[File:small_sprint.gif|top|link=]] '''Fleeing''' from zombies inside the ruin will not wound you, but will cost you valuable {{O2}} (Reports vary from 5% to 10%). Zombies are spawned randomly each day, in groups ranging from 1 to 4. At any time, there can only be a maximum of 4 zombies in one zone. 

{{MetaInline|Control Points}}, {{MetaInline|Camouflage Suit|displayname=Camouflage Suits}} and {{MetaInline|Flash Grenade|displayname=Flash Grenades}} do '''NOT''' work inside the ruin, however {{MetaInline|Pre-war Camera}} will relocate all zombies to another "zone" in the explorable ruin if successful. {{MetaInline|Armoury|displayname=Weapons}} work as usual, but {{MetaInline|Furious Kitten (partially digested)}} '''CANNOT''' be used inside the ruin.

If the ruin is within 11km or less, a [[hero]] can use [[heroic return]] inside the ruin to exit immediately. Note that each heroic action can be performed once only during his life in each town. 

== Doors and Keys ==
Each {{MetaInline|Explorable Ruins|displayname=Explorable Ruin}} will have 10 rooms that explorers can search for items. Some rooms closer to the [[File:small_exit.gif|top|link=World Beyond]] [[World Beyond|Entrance]] will be opened by default while the remaining rooms deeper in the ruin will be locked. 

Each locked room will be locked by one of the three types of key mentioned below. {{MetaInline|Technician|displayname=Technicians}} can make a blank of the required key by clicking on "Taken an Impression" button when they are in a zone with a locked door. Each technician can only make one blank from the same door once per trip (each day). More blanks of the same door can be made by other {{MetaInline|Technician|displayname=Technicians}} on the same day provided the door is still locked. Each blank can be turned into the corresponding key in the {{MetaInline|Workshop}} for varying {{AP}} costs. Anyone can convert impressions. {{MetaInline|Technician|displayname=Technicians}} do not have any bonuses in converting key imprints.

There are three different kinds of keys with three corresponding blanks:
* {{MetaInline|Bottle Opener}}
* {{MetaInline|Bottle Opener Blank}}
* {{MetaInline|Bump Key}}
* {{MetaInline|Bump Key Blank}}
* {{MetaInline|Magnetic Key}}
* {{MetaInline|Magnetic Key Blank}}

These keys can also be found regularly by searching the opened rooms. Note that, for example, a {{MetaInline|Bottle Opener}} from a blank from Room A can also open Room B as long as Room A and Room B require Bottle Opener to open the doors. Room A and Room B can be in two different Ruins entirely. The key will be consumed once used.

==Distinctions==
Each entry into the ruin (limited to once per day) will give the {{MetaInline|Ruin Exploration}} distinction. Each locked door opened will give a rare distinction {{MetaInline|Covert Concierge}}.

== Blueprints ==
Each ruin has a low chance of dropping {{MetaInline|Blueprints}}. These blueprints are currently different from the normal blueprints found in {{MetaInline|Worn Leather Bag|displayname=Worn Leather Bags}}, {{MetaInline|Architect's Chest|displayname=Architect's Chests}}, and after {{MetaInline|Camping}} normal {{MetaInline|Ruins}}. Normal blueprints can unlock any building projects from the whole pool, while ruin blueprints only have a preset pool of projects which can be unlocked. 

When a blueprint is read, it will always try to unlock a project which can be unlocked first. If there is no project left which is lockable, it will fail and the blueprint will be wasted when you read it.

If one of those projects have been unlocked by the normal blueprint, you will have one fewer building project which can be unlocked from the ruin blueprints. Thus normally you want to hold all normal blueprints and read ruin blueprints to unlock all preset building projects first. For that reason, the practice of holding off reading normal blueprints until explorable ruins cease to yield any more of their own is preferred.

However if all projects left from the preset pool are child projects which require their parent project(s) to be unlocked first, and their parent project(s) is/are not inside the preset pool, you need to switch the preference and start reading normal blueprints until you can unlock the target parent building. Only then you can switch back and read ruin blueprints again. 

We can differentiate normal blueprints from the ruin blueprints by looking at the item icons and IDs (visible in the XML feed). The icons of different ruin blueprints are as follows:
* [[Abandoned Bunker]]: [[File:Item_bbplan_u.gif‎]] [[File:Item_bbplan_r.gif‎]] [[File:Item_bbplan_e.gif‎]]
* [[Abandoned Hospital]]: [[File:Item_hbplan_u.gif‎]] [[File:Item_hbplan_r.gif‎]] [[File:Item_hbplan_e.gif‎]]
* [[Abandoned Hotel]]: [[File:Item_mbplan_u.gif‎]] [[File:Item_mbplan_r.gif‎]] [[File:Item_mbplan_e.gif‎]]

Normal blueprints from worn leather bags, architect's chests, and normal ruins have the following item IDs and icons:
* 305. {{MetaInline|Construction Blueprint (common)}}
* 306. {{MetaInline|Construction Blueprint (uncommon)}}
* 307. {{MetaInline|Construction Blueprint (rare)}}
* 308. {{MetaInline|Construction Blueprint (very rare!)}}

And blueprints from each ruin have different item IDs from normal blueprints and also from each other! In other words, an uncommon blueprint found at the [[Abandoned Hospital]] will not stack with the uncommon blueprint found at the [[Abandoned Hotel]] and the [[Abandoned Bunker]]. As noted, hospital blueprints will have different pre-set projects available compared to bunker or hotel blueprints.

The following is an '''incomplete''' list of possible projects available by each ruin blueprints. This is a work in progress, not a final product just yet. Please free free to add onto the list!

== Mapping ==

[[File:paper_mapping.png|thumb|A digitalized version (for illustrative purposes only) of mapping technique using only a copybook and a pen at hand.]]
[[File:Annette-penil-and-paper.png|thumb|An example of an initial map using "pen and paper" with various symbols. Screenshot by Annette.]]
[[File:split-screen_spreadsheeting.png|thumb|An example of using character codes for split-screen spreadsheeting.]]

Building map is 13x13 squares. Towns often organize to make a spreadsheet map of the building's interior layout. First players to venture inside are being tasked with mapping the building's layout. It can be done in various ways, complementing each other but capable to achieve the result desired on their own. The choice has to be based on which way a player finds more convenient in relation to their own skills.

* '''Screen-recording software'''. It may be useful to notice all the details upon reviewing, such as zombie counts, lock types, and items found. However, it may prove to be difficult to find the way out on the first trip without using other means of mapping. Fine memory can be of great help if one relies on this technique alone. A free and easy to use screencast program is [http://www.screencast-o-matic.com/screen_recorder Screencast-O-Matic]. 
* '''Pen and paper''' (preferably with a grid), using junction shapes or other symbols. Takes little time and shows the big picture, as the mapper moves around, allowing to see if there are any turns missed as well as to easily navigate to the [[File:small_exit.gif|top|link=World Beyond]] [[World Beyond|Exit]].
* '''Split-screen spreadsheeting''' (opening a sheet in another window and aligning both windows next to each other) using a set of characters for quick marking. However, the coded version needs to be visually furnished for others to navigate, making this technique on par with pen an paper. The only difference is the mapper's preference.

A reliable method is to combine pen and paper method with a video recording of your trip to confirm that your map is 100% correct.

== Notes ==
* Before [[Season 9]], There is a bug which makes you escape from the explorable ruins effortlessly. You have 2 tabs open, one being outside and another being inside the ruin. You can leave the ruin anywhere inside simply by leaving the zone on the outside tab. See [http://youtu.be/0PGEwAsxj9k the video]. This bug is fixed in [[Season 9]].
