The Proximity Mine is a military-grade mine that goes off when enemies come near. It does the same job as the crafted Proximity Bomb. Use it to set up an ambush or cover a Horde's route.
Place mines across a choke point before a Horde fight. They also cover a door while you loot or wait out a patrol.
The Proximity Bomb is the crafted version, made from a can, spark igniter, gunpowder, nails and scrap. Craft bombs when parts are plentiful and save mines for when you run dry.
Crossbow
The Crossbow is an Average-condition special weapon for silent kills. It reloads slowly, but bolts make no noise. It gets more useful as you unlock more bolt recipes.
Drifter Crossbow
The Drifter Crossbow is the Military Spec upgrade to the standard crossbow. It is still silent, and it fires every bolt type: standard, Residue, Incendiary, Poison and Explosive. It is the best special weapon for stealth.
IPCA Stun Gun
The IPCA Stun Gun is a taser on the Survival Wheel. You earn it by collecting all 18 pieces of IPCA Tech. It stuns Freakers and sometimes sets them on fire, but both prongs have to hit.
Proximity Bomb
The Proximity Bomb is a crafted trap that goes off when enemies get close. Its recipe sits in the Berley Lake Ambush Camp bunker. Place them in a Horde's path or at a door you expect enemies to use.
