R6 Vegas 2 is even worse than I remember, playing the SP to get sharp for MP with friends. At the hardest difficulty it is an exercise in frustration. I'm fine with dying easily as...that is the point of R6. But the way the levels are designed it seems you're funneled from killzone to killzone (why there's not a bigger response to these mercs and Mexicans deploying companies in Las Vegas than the three guys they send, I'm not sure).
Still, as a COD game it would be pretty good.
