File:Quake1.gif Water in Quake is a Fluid that can be blue or brown, it is harmless when the player walks across or swims in it unlike Slime and Lava. However, it can become a hazard as well if the player remains underneath it for too long. Thus the player must either come up for air frequently or acquire a Biosuit, the latter option will allow the player to stay underwater longer. Moving underwater will move the player in the z-axis according to facing. There are also buttons for swimming up and down. Swimming up as soon as you hit the water will protect you from fall damage.
