Broken AI and a weak story keep AO2 from capturing your heart.
Salem and Rios, the main characters and army rangers, quickly learn that they could be making more money in privatized military, so they leave the army and and become mercenaries for hire. You play as either one of these soldiers of fortune during the modern day war in Iraq.
Sounds good right? Too bad it's only true half of the time.
If you're playing with another friend cooperatively then AO2 is a blast. On the other hand, if you are playing on your own then your experience will be very frustrating. The proficient graphics engine delivers clear and crisp visuals while keeping the frame rate well above 30. Furthermore, the gameplay, while similar to the GOW franchise, feels fresh and exciting. Sound effects are realistic and satisfying.
The AI is noteworthy too, but not in a good way. If you are playing single player then the friendly AI will drive you up the wall. Your friend will dive out of cover if he's at low health, run into enemy fire, etc. It's a real nuisance because you only have limited control over his actions.
What you end up with is a divided game. It's a lot of when played with a friend and very frustrating when played alone. It's no GOW game, but it's an average filler until the third instalment is released.
