Traps

SAM Site

Shoots down aircraft over your base, from minicopters to balloons. It needs 25 power and a supply of missiles, so it suits a group that already has electricity.

Overview

In-game description
A surface to air rocket site. Requires 25 electricity to function.

The day a minicopter starts dropping people on your roof, you will want one of these. It fires guided missiles at aircraft around your base: minicopters, scrap helicopters, hot air balloons. Against anyone on foot it does nothing.

Two things keep it alive. It eats SAM ammo, and every missile takes gunpowder, a metal pipe and a Level 2 bench, so keep a box of them stocked. And it needs 25 power for as long as you want it watching the sky.

  1. Place it high, on a roof with an open view of the sky.
  2. Run power to it. A small generator puts out 40 by its own description, which covers it with room to spare.
  3. If you run a large solar panel instead, add a large rechargeable battery so it does not go dark at night.
  4. Load the missiles and check that it shows as powered.

Nobody can craft or research the site itself, so the high quality metal listed for it is never spent: it comes only from loot or a trade. Once you have one, the real running cost is the missiles.

Recycling

Recycler

At power grid stage 2 a green recycler works at 60% instead of 50%. Yields depend on the recycler.
