The Water Balloon is a very random weapon that can deal a decent chunk of damage if you get lucky. When shot, it will choose a random flight path that is within a couple degrees of a normal flying shot, bounce a small distance with random amount of times on the ground and once done, it explodes into a spray of 10 water projectiles that spreads to both sides, dealing distance scaled damage. Only the water from the balloons deal damage, as any balloon impacts does nothing. Due to its random nature, it is advised to use this weapon against groups, where hitting the general area is enough. It is worth noting that the water balloon may not bounce at all and explode once it hits the ground. This tends to happen more often if the balloon lands near an enemy tank.
Water Trio follows most of Water Balloons rules with few exceptions. The damage maximum per projectile has been reduced by 1 and 3 balloons are shot that deviate from the actual trajectory even more, making groups a crucial part in dealing good amounts of damage with this weapon.
Water Fight is the reward for dedicated spraying and praying. It fires 10 Water Balloons, that stick surprisingly close together covering about the same deviation from the normal flight path as the previous ones. An interesting change here is that each Water Balloon now only contains 5 water projectiles and those have their max damage reduced to 6. Remember how you got here and pop those balloons like a monkey.
