Swimming Controls Guide
As of the current patch, Swimming in the battle area causes some bugs. In this case, any player submerged underwater will not take damage from gunfire.
In order to perform a dive, jump into the body of water then while on the surface, align your perspective downwards then hold the W key. This causes the player to become fully submerged. To submerge yourself again, simply press and hold CTRL key. The latter can be performed without having to tilt downwards.
As mentioned above, since the water provides cover from being flanked by bullets, one trick is to dive underwater then swim across the lake or stream while fully submerged. Although the player cannot stay submerged for extended periods of time, this temporarily grants invincibility against any hostile enemies that lurk on the land. Another advantage of swimming underwater is that you can outrun those who swim on the water’s surface.
Next time you feel like going for a dip with an exposed freestyle, be sure to do it underwater instead.
