Terminator Salvation is a third person action game where you assume the role of John who battles alongside various resistance fighters. You'll be fighting the Skynet forces in run down locations across the city and generally kicking robotic butt across 9 levels. The game offers a simplistic and easy to use cover mechanic where you're able to move around cover by holding a direction and pressing a button. Sadly, not all cover can be used and if there's no on-screen prompt, then you're going to be out of luck. This can get a little tiresome at times, but is something that you'll have to work around. The game throws you into various encounters where the gameplay onus is on flanking the enemy by moving into position using said cover system.
