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 60 m 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.

Material	Grade	Melee	Bullets	Explosions	Infected	Upkeep per day per 1,000 health	Repair item	Health per repair item
Ungraded	0	x1	x1	x1	x1		Scrap Metal	150
Wood	1	x1	x1	x1.25	x1	1 x Firewood	Firewood	130
Reinforced	2	x0.5	x0.6	x1	x0.75	1.2 x Scrap Metal	Scrap Metal	160
Sheet Metal	3	x0.1	x0.3	x0.9	x0.45	0.25 x Steel Sheet	Steel Sheet	900
Concrete	4	x0	x0.12	x0.7	x0.3	0.5 x Sand, 1 x Stone	Stone	260

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 7 m 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.

Once a base has been attacked by survivors it stays open to attack for 45 minutes, even if everyone who lives there logs off. 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	12 L	0.7 L/h	17.1 h	45 m	Diesel (1.3 L each), Fuel Can (10 L each), Kerosene (0.8 L each)
Generator	Generator	4,000 W	30 L	1.6 L/h	18.8 h	70 m	Diesel (1.3 L each), Fuel Can (10 L each)
Diesel Generator	Generator	9,000 W	60 L	3 L/h	20 h	110 m	Diesel (1.3 L each), Fuel Can (10 L 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
Cable Pole	Cable point									60 m
Junction Box	Cable point									32 m

One Power Cable covers 10 m of run. A run between two ordinary pieces can be 25 m 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 at 3 m/s of wind (6.7 mph) and reaches its full output at 12 m/s (26.8 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
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

Electric Fence	250 W	All the time	No
Workshop Bench	250 W	While someone is using it	No
Tool Wall Bench	200 W	While someone is using it	No
Workbench	200 W	While someone is using it	No
Armoured Sentry Gun	150 W	All the time	No
Fridge-Freezer	150 W	All the time	No
Sentry Gun	150 W	All the time	No
Studio Light	150 W	At night	No
Grow Light	120 W	All the time	No
Lamp Post	100 W	At night	No
Ward Chime	100 W	All the time	Yes
Work Light	80 W	At night	No
Under-Counter Fridge	70 W	All the time	No
Work Lamp	60 W	At night	No
Base Radio	50 W	All the time	No
Tripod LED Lamp	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 sheet metal, and eat 10% of each stack they reach.

Locks

A lock fits one container, door or gate. Without one, 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.

Fitting a padlock gives you its key. Copies are cut from a Key Blank at a Workshop Bench in 9 seconds.

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	16 s	40%	35%		It is silent. Each point of Crafting skill adds 0.4% to the chance.
Bolt Cutters	Padlocks	7 s	100%		35 m	The padlock is cut off and ruined.
Oxy Cutter	Keypad deadbolts	45 s	100%		60 m	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.
