How to get a Water Pistol

After completing Main Mission 18, you get the key item for unlocking the Water Pistol. A decent level of R&D team and GMP required to built one. The Water Pistol is upgradable(higher effective range stat) and the max upgrade requires R&D Team level 52.

Where to use the Water Gun

Holding Up:

If you hold up the Water Pistol against the enemy soldier just like the other weapon in the game. This doesn’t lose the ability of incapacitating enemies. Check out the picture below for the use.


Try shooting near any enemy soldier to distract them with the sound. This buys some of their time to investigate it without getting alerted as they do not consider this noise as an attack.

Fire Extinguisher:

You can even shoot at the torches and fire pits to extinguish them making it darker environment.

Stun Effect:

Shoot directly on the enemy’s face to stun them for that moment(3-4 seconds). If You’re fast enough you can use it to stop the alert. Mostly used when CQC have been too slow.


Definitely works as the electronic disabler. Works Best on Communications Equipment (the Radar Dishes), Radio Transmitters, and the Power Supply the way of crippling the enemy. Just One shot and it’s done.
