Taking damage and the consequences of dying | Combat Watch Dogs Guide

The stains on the screen let you know about the low health of your character

Just as I mentioned earlier, Aiden does not use any special armors, throughout the game and, as a result, he is not too resistant against effective enemy fire. You need to remember about that and react appropriately to dangerous situations. Just like in the majority of today's shooters, damage that you receive is symbolized by the red stains that appear on the screen, and distortion of vision. It lets you know that you necessarily need to hide, e.g. behind a cover or inside a vehicle. The health of your character regenerates spontaneously, but taking additional damage interrupts this process.

If you fail to escape, or hide, in time, Aiden will lose his entire health bar and die. There are no dire consequences, in Watch_Dogs so, you do not need to worry about, e.g. losing your cash or the equipment. IF you have played one of the missions, at the moment of dying, you will be restored to the most recent checkpoint (the game creates them very often). If, however, you died during the free exploration of the city, after a short while, you will respawn next to the hideout nearest to the dying place.
