Tripwires are a craft-able trap that players can leave around the map, that will detonate whenever a player or AI steps in the wire. When the wire is tripped, there is a slight delay before the explosion of the attached grenade, but not enough to escape. The explosion is equal to that of the attached grenade, and equally as deadly. Tripwires stay on the map for a very long time, and persist past restarts. Its common for players to get kills with Tripwires while they are offline. An interesting quirk with the Tripwires, is that if the player who set it is online, the killfeed will show the exact distance between the online player, and anyone unfortunate enough to die to their trap. This can result in Tripwire kills over many Kilometers, and it is the only legitimate way to get a kill at that distance.
