It's a Trap!

It's a Trap!

Your base deserves better than a wall. 45 traps built from vanilla junk: spiked logs, punji pits, snares, glass carpets, jaw traps, drop cages, poison darts, fuel slicks, shock mats, radio lures, sentry shotguns, pot bombs and propane bombs. Zombies always trigger them and always get hurt. Animals and players can too, depending on your sandbox settings.

How it works

• Learn: five very rare recipe magazines, one per volume, turn up in fitting places: hunting and survival stores, hardware and metal shops, labs, electronics stores, gun stores and military storage. Until you read one, its recipes stay hidden.
• Craft: traps are endgame. They need lots of vanilla materials, kept tools and real skill levels (Trapping first, then Carpentry, Metalworking, Electrical, First Aid, Cooking or Aiming). You get a trap kit.
• Place: right-click a square, It's a Trap! > Place trap here, or place it at your feet from the inventory. Tripwires take two clicks: start, then end, in a straight line.
• Rearm cheaply: a fired trap needs Rearm: a couple of nails, a bit of twine, some gunpowder. Many mechanical traps rearm for free. Each trigger uses 1 durability. Broken traps can be repaired for half their materials or dismantled.
• Pick up a disarmed trap to get the kit back, durability and loaded ammo included.

Triggers

• Pressure: someone steps on the square.
• Area: anywhere in a 2x2, 3x3 or 1x2 footprint.
• Tripwire: anything crossing a straight line of up to 8 tiles (walls block placement).
• Proximity: a motion sensor with a 2 to 6 tile radius.
• Remote: craft the Remote Trap Detonator, right-click your remote traps to link them, then detonate them all from the inventory within 60 tiles.
• Timer: counts down from placement or rearm.
• Door: fires when the door on its square is opened.
• Beacon: pulses noise every few seconds while its battery lasts.

Effects

Damage, deep wounds, glass, fractures, bleeding over time, knockdown, stagger, being held (snares, jaws, cages, nets: players can struggle free with Strength and Fitness), pits that hold zombies and may turn them into crawlers, poison, fire, explosions with falloff, shrapnel, electric shocks (grid, generator or a loaded car battery), noise lures, alarms, smoke, gas clouds, gunfire with real ammo you load, and chain reactions between your own traps.

Hidden traps & counterplay

Armed traps are hard to notice. Other players only get the trap's menu after spotting it: a chance every second based on Trapping and distance, and always when adjacent and sneaking. A spotted trap can be disarmed and stolen at half durability. Fail the Trapping check and it fires on you.

Zombies always trigger traps and always take damage, whatever you set.

Singleplayer & Multiplayer

Works in both. In multiplayer the server owns every trap: placing, rearming, disarming and triggering are all checked there (distance, owner, items, state, rate limit). Detection is a cheap throttled scan over armed traps only, and it never runs code per zombie.

Compatibility

• Build 42 (42.21).
• Standalone, no requirements. Only vanilla sprites, icons, sounds and items.
• Adds items (kits, 5 magazines, a detonator), so removing it from a save deletes those items. Placed traps disappear with it.
