What does the Fragmentation Grenade Do?
The fragmentation grenade will explode, causing fragmentation, which increases the deadliness of the average grenade.
How does the Fragmentation Grenade work?
The grenade has a triggering pin, you pull that, and throw it at your opponent, while its having a few second delay. When the delay is over, the grenade explodes, causing it to split up into fragments that can injure your opponent and his allies around him!
