The Halloween grenade
Respawnables - Halloween Grenades
The Halloween Grenade is a special gadget that was available during the Halloween update but cannot be purchased anymore. They costed 750 cash and when thrown,takes 1 second to detonate,a flare marking it's location before detonating and marking the location of any player caught in the blast,assuming they survived.Since the update,they have been removed from the store but are still usable if you had purchased and kept them before the update. Though the recent Grenade Fest Update has brought these wonder grenades back into respawnables. So I suggest you keep them!
Advantages over Frag
It has a Flare to signify where it is going, has 1 less second for a fuse and all at the same price. The radius is slightly bigger, allowing more hits and tags victims with bats, easily tracking down camo in Snow Village. The smaller fuse makes it close to the Super Grenade.
Disadvantages
along with normal frag problems, some people may find the smaller fuse debilitating. It has 75% dmg of the frag, and can be useless unless flanking or trapping someone with barrels. Anyone with at least 2 speed can dodge the bomb without trouble. And it takes longer to reload, and the flare can give away the position. Whether you want this, the frag, or something else is a matter of personal preference.
