The Poison Grenade releases a cloud that can turn soldiers against each other. Throw it into a group, step back and let them fight it out.
Throw it into a packed group and keep your distance. Poisoned soldiers will fight each other while the gas drains their health. Stay out of the cloud yourself.
El Besito and the Fantasma Supremo spread the same kind of poison. Gear that adds damage to poisoned enemies helps you finish off survivors.
Bait
Bait is a chunk of meat you throw to draw predators to a spot. Toss it near FND soldiers and let the local wildlife do the fighting, or use it to bring out animals while hunting.
C4
C4 is a remote-detonated explosive you place and trigger when the moment is right. It is your best tool for setting traps on roads, wiping out parked vehicles or blowing up a target without being nearby.
Dynamite
Dynamite is a timed explosive built for wrecking vehicles rather than soldiers on foot. Throw it under an armored car or tank and get clear before the fuse runs out.
EMP Grenade
The EMP Grenade shuts down vehicles, cameras and alarms in its blast. Throw one before you sneak into a base to blind its security, or stop a vehicle dead in its tracks.
