The Napalm Grenade explodes, then spreads a viscous napalm substance in the immediate area (hereby referred to as 'flames'). The flames spewing from the grenade take on the grenade's velocity in addition to a smaller, random vector. As the grenade explodes and the flames fly out, if a flame strikes a victim it will stick to them, causing damage and setting them on fire. If a flame sticks to the player, it is removed from the world. Any flames that did not strike a player will fall to the ground and settle, still burning. Flames on the ground emit a thick, black acrid smoke that can block visibility in confined spaces such as corridors. Running through any flames on the ground will cause damage, but not as much as a direct strike. Once the grenade expires, the smoke persists for a few more seconds.
