The Remote Explosive is an explosive trap in The Culling. It is remote detonated, which can be activated with left click. It does 60 damage and has a massive blast radius, so make sure you are not near it when it detonates. The remote explosive however is very easy to spot, so it is most effective when placed in plants, around corners, and behind doors. Its placement speed can be sped up with the perk Trapper. Be careful around it as well, since it will be detonated if something hits it.
The Remote Explosive can be found in item crates.
