An excerpt from the review -
"The story lasts about the same length as the last outing of dlc, with a few variations in the missions here and there. In all honesty, they are fairly menial; some missions are just plain uninteresting or downright frustrating. Did you enjoy the eagle flying mission from the main game? No? Well you're in luck, because there is some more of that in The Betrayal. In addition, and I shit you not, two missions have you playing checkers. CHECKERS?!"
