The Spider Grenade only appears in the campaign of Resistance 2. It contain an airtight vial of concentrated necrotoxin harvested from the salivary glands of Marauders. Once the substance hits oxygen, it catches fire and propagates at an alarming rate, causing severe tissue damage to anyone who comes in contact with it. If thrown correctly one of these can take out three Titans at once. The toxin's only drawback is its lifespan; fire consumes it after short periods of time.
