To get a water gun, you must purchase the Sunburn DLC or buy one directly from another player. It comes in default, grey, green, orange, and yellow. The water gun doesn’t deal actual damage. Instead, it applies a wet debuff, which is also caused passively through a splash effect. Knowing this, shooting players with the water gun while in the arctic biome can cause players to die if they aren’t able to get dry fast enough.
The water gun uses Water or Salt Water as ammunition and is refillable via rivers or oceans. Once filled, players must pump up the water gun like a real-life water gun by holding R. Once primed, players may fire a steady stream until pressure is lost and priming is required again.
The maximum water capacity for the water gun is 1000ml.
