The video game Terminator Salvation has an in-depth cover system that has been compared to the system used in Gears of War.TeamXbox: Exposed: Terminator Salvation's Cover System (April 29, 2009)

A core gameplay element of the game is the cover system. The main character in the game is John Connor, and he navigates through the different levels with the help of squad members. The player must coordinate with his squadmates to strategize and effectively use the environment. Combat takes place all around the player, 360 degrees, and it's important to take advantage of the cover offered by different objects while tracking enemy locations as they move around.

The cover system has been compared to Gears of War. Approaching objects that can provide cover will cause a button prompt to appear on screen. Once concealed behind an object, players can blind fire or aim more precisely. Grenades and pipe bombs can also be tossed blindly at enemies from the safety of cover. It's also possible to slide the length of the concealing object in order to find a better position.G4TV: Terminator Salvation Direct-Feed Walkthrough (Cover System info) (Time: 9:28)

Enemies can destroy the cover that players hide behind, making it necessary to continually advance or retreat while seeking out new locations to hide behind. One way to do this is to press forward, or toward the object, with the analog stick. This causes an indicator to appear onscreen that shows other potential hiding spots within John's reach. Roll the stick to select one of the proposed locations and John automatically scurries from his current place of concealment to the next.TeamXbox: Exposed: Terminator Salvation's Cover System (April 29, 2009)
