LOL! Yep, it gets insane at times. Especially when you are playing it alone. The enemy focuses their attack on you alone. I played for a couple hours on the Xbox this morning using the soldier. The deployable turret levels the playing field and draws fire. Now the soldier can reclaim it before it is spent if needed. That is an improvement over the original game. Previously, once you deployed the turret it would stay until it was spent regardless if it was shooting or not. All the players action skills have a cool down period before they can be used again. So if you reclaim it, the cool down period is shorter. I noticed that the enemy AI seems a little bit smarter now. They will try to flank you to gain an advantage.
Good times, fun stuff for what it is.
