Highly underrated
The AI is really good in single player but make sure you use cover and check your corners because you WILL get flanked by the enemy if you try to run and gun it. Army of Two TDC is very focused and most importantly EXTREMELY FUN with a decent amount of customization for your characters and weapons. I'm glad the developers used their time to focus on the games strengths instead of wasting time on half baked PvP or some other gimmick that you would play once and never play again. So do yourself a favor and buy it now if you can afford it or simply wait until its cheaper if you like shooters.
