The GeeZee fires three projectiles for the cost of only one ammo, its accuracy is high and does not diminish with firing. Projectiles have high speed and inflict high damage.
The thing that detracts from its effectiveness is that its projectiles go straight through most targets and only very large targets may be hit directly. As a result, when using this weapon, the only real way to deal any damage to normal targets is to hit the ground under the target or a wall next to it. This can take some getting used to, and makes the rocket launcher a little frustrating.
