Ghost Bomb shoots a single projectile that has a fairly large explosion radius. Although not as powerful as Nuke, Ghost Bomb can serve as an alternative for players who are yet to unlock Nuke. Ghost Bomb also does not damage terrain, making it useful for hitting multiple enemies while keeping your aim on them.
Ghostlets shoots 5 smaller ghosts that have both decreased damage and splash radius. Ghostlets can be used to hit a large area on the map, or can be concentrated against a single target for increased total damage.
