The Radiation Grenade is a type of grenade in The Conduit. It is also sometimes known as the Rad Grenade. It is of Drudge origin, as these species are the only ones who use it in the campaign mode.
When it explodes, it emits red pulses of radiation for a few moments, dealing damage over time to those nearby. This grenade can also be used as a sticky grenade that will attach itself to a player is they are hit directly with it when thrown, if stuck, the grenade does far more damage to the player than if they had simply been near the grenade when it was detonated. This may sound similar to the Plasma Grenades of the Halo series, but they still operate as grenades while radiation grenades drain the player of energy over time by continuously emitting radiation.
Other relations
The Radiation grenade can be compared to a "bio warfare bomb" in real life, where the bomb has radiation in it or a virus/ sickness that is released when the bomb explodes.
