Base building

Walls, floors and defenses

Every wall, gate, floor, roof, tower and shelter you can place, with the kit that places it, what it is made of and how much damage it takes. A piece with an entry under Upgraded from is not placed from a kit of its own: you place the earlier piece and upgrade it with a hammer.

You need a hammer in your pockets to upgrade or repair. An upgrade takes 6.5 seconds, and a piece that was hit in the last 60 seconds cannot be upgraded.

Taking down an upgraded piece returns 50% of the upgrade materials. A destroyed piece drops 25% of its materials.

One survivor can own 80 pieces, and nothing can be built within 197 ft of a safe zone.

Material grades

What a piece is made of decides how much of each kind of damage gets through, what its upkeep costs and what a hammer repair uses. The multipliers apply to the damage numbers in the next table: x0.3 means the piece takes 30% of the hit. A grade is not an upgrade tier. On the frame kit every piece goes from Timber to Stonework to Sheet Metal, and those tiers are the Timber, Stonework and Sheet Metal grades below, each tougher than the last against everything. The Blocks house kit is a separate system: its masonry and concrete walls are the Concrete grade, and its clad timber is Reinforced.

Ungraded pieces are tents, camp gear, stations and lights. Each one costs 0.15 x Scrap Metal a day in upkeep instead of a cost by health.

A repair takes 4 seconds per item.

Damage to structures

How much health one hit takes off a piece before its material is counted. Multiply by the column of the Material grades table named under Counts as.

Source	Damage	Counts as	Notes
Melee hit	10	Melee	The base hit, scaled by your melee skill.
Pistol round	3	Bullets
Submachine gun round	3	Bullets
Rifle round	5	Bullets
Shotgun shell	8	Bullets
Sniper round	14	Bullets
Any other firearm	3	Bullets
Explosion	400	Explosions	This is the damage at the center. It falls to nothing 23 ft away.
Infected clawing at it	6	Infected	Each infected pressed against the piece does this every 2 seconds.
Breaching Charge	900	Explosions	Set by hand on a 8 second fuse. It does this to every piece close to it.
Thermite Charge	600	Explosions	Set by hand on a 5 second fuse. It does this to every piece close to it.
Remote Charge	500	Explosions	Set by hand and fired by remote. It does this to every piece close to it.
Pipe Charge	350	Explosions	Set by hand on a 12 second fuse. It does this to every piece close to it.

A blast takes the lock off a container, door or gate before it harms the piece itself.

A base can be raided at any hour, even while everyone on its list is offline. Nobody can build, take pieces down or change who has access while it is under attack.

Claims, upkeep and decay

A Base Cupboard claims the ground around it. Only survivors on its list can build there, and it pays the upkeep of every piece inside from the materials you put in it.

Squadmates and allies of anyone on the list count as on the list unless the builder turns that off.

Power sources, batteries and cabling

What makes, stores and carries electricity in a base. Output is the most a source gives; fuel use is at full load, and Runs for is one full tank at full load.

Piece	Type	Output	Tank	Fuel use	Runs for	Heard from	Takes	Stores	Charge and discharge	Cable reach
Small Generator	Generator	1,500 W	3.2 gal	0.18 gal/h	17.1 h	148 ft	Diesel (44 fl oz each), Fuel Can (2.6 gal each), Kerosene (27 fl oz each)
Generator	Generator	4,000 W	7.9 gal	0.42 gal/h	18.8 h	230 ft	Diesel (44 fl oz each), Fuel Can (2.6 gal each)
Diesel Generator	Generator	9,000 W	15.9 gal	0.79 gal/h	20 h	361 ft	Diesel (44 fl oz each), Fuel Can (2.6 gal each)
Solar Panel	Solar	150 W
Solar Array	Solar	600 W
Wind Turbine	Wind	1,200 W
Battery Bank	Battery							6,000 Wh	2,500 W
Breaker Panel	Cable point									79 ft
Cable Pole	Cable point									197 ft
Junction Box	Cable point									105 ft

One Power Cable covers 33 ft of run. A run between two ordinary pieces can be 82 ft long, and one piece can feed 8 cables.

A running generator with nothing drawing from it still burns 25% of its full-load fuel, and the infected hear it every 20 seconds.

Solar panels work from 6:00 to 20:00 and peak at noon. Under full cloud they still give 15% of their clear-sky output.

A wind turbine starts turning in a 7 mph wind and reaches its full output at 27 mph.

What draws power

Every piece that needs electricity, how much it draws and when. Add up what runs at the same time to size your generator, panels and batteries.

Piece	Draw	Draws	Works without power
Table Saw	1,800 W	While someone is using it	No
Cement Mixer	650 W	While someone is using it	No
Armory Bench	400 W	While someone is using it	No
Water Pump	400 W	All the time	No
Med Station	350 W	While someone is using it	No

Base Radio	50 W	All the time	No
Ceiling Light	40 W	At night	No
Tripod LED Lamp	40 W	At night	No
Wall Light	40 W	At night	No

Lights that run at night switch on from 19:00 to 7:00. A crafting bench keeps drawing for 3 minutes after someone last used it.

When there is not enough power for everything, electric fences and sentry guns are fed first.

Storage

Every piece that holds items, with how many stacks and how much weight it takes. All of them take a lock.

When raiders smash or blow up a container, each stack inside keeps between 45% and 80% of its count and a single item survives 65% of the time. A container lost to decay or the infected spills everything.

Rats get into food kept in storage made of anything weaker than metal, and eat 10% of each stack they reach.

Locks

A container takes one lock; a door or gate takes two, one of each kind, and opens only when both let you in. Without a lock, anyone standing at the piece can open it. Blast strength is how much explosive damage the lock takes before it is blown off.

Lock	Blast strength	Time to fit	How it opens
Padlock and Hasp	250	5 s	Opened by anyone carrying a key cut for it.
Keypad Deadbolt	600	9 s	Opened with a four-digit code.

Every padlock is stamped with its own four-character number, and its keys carry the same stamp. A new padlock comes with its key; one taken off keeps its stamp, so its old keys still open it wherever it hangs next.

Copies are cut from a Key Blank at a Workshop Bench in 9 seconds.

A keypad runs on its own nine-volt battery, never the base grid, so a power cut doesn't open it. A fresh battery lasts about 29.76 days standing by, less with use. Below 15% it chirps and blinks; flat, the bolt stays thrown for everyone until a battery is held to its contacts and the code typed. The battery is changed from the inside.

A keypad refuses every code for 60 seconds after 3 wrong tries. Each lockout is twice as long as the last, up to 15 minutes.

Forcing a lock

The ways past someone else's lock without the key or the code. A lock can only be forced when the base can be attacked at all.

Tool	Works on	Time	Chance	Tool breaks	Heard from	Notes
Lockpick Set	Padlocks					Skill, not luck: a padlock has 4 pins to set one at a time with the right tension on the wrench. Lean too hard and the pick snaps and is gone. Feel for the Pins and Locksmith's Touch widen the sweet spot and let you feel the binding pin. The scrape is quiet but carries ten feet or so.
Bolt Cutters	Padlocks	7 s	100%		115 ft	The padlock is cut off and ruined.
Oxy Cutter	Keypad deadbolts	45 s	100%		197 ft	It cuts the bolt through.

Explosives work on both kinds of lock: the blast has to do more damage than the lock's blast strength.

Sentry guns, wards and hordes

The numbers behind a base's active defenses and the hordes they answer. A sentry gun runs off the power grid, feeds from its own ammo box and can be set to shoot only the infected or hostile survivors as well.

Hordes only come while someone who lives at the base is home. Bigger, louder and brighter bases draw them more often, and more often at night.
