Cover System

The Cover System is a new feature in the GTA Series. The first appearance of the cover system is in Grand Theft Auto IV and its downloadable episodes The Lost and Damned and The Ballad of Gay Tony, although it is the one that is not so different from the one used in the Gears of War series.

Description
By pressing a button, the Protagonist will hide behind the nearest available cover, with a great number of animations for each way he enters cover (such as crouching behind a car, rolling to reach a cover faster, and even sliding on his knees).

Behind cover, the player can lock-on enemies (or manually aiming to them) exposing himself when the fire button is pressed, and retreating back when he ceases fire. The protagonist can also blind fire, but the accuracy is significantly decreased and the player is unable to lock-on to enemies.

In Multiplayer, using cover can save your life in many occasions. However, during multiplayer (PARTICULARLY Team Deathmatch), using the cover system is very cheap, as you can easily kill people without exposing yourself. Also, there is corner glitching, where a person BARELY loks around the corner to lock onto a target, and moves the slightest distance out to kill that person from the corner.
