It was a bit of a dissapointment, but then again that was more of my fault for expecting it to be more than just doom with awesome graphics.It was fun the first time through, but does get to be repetetive.
But it's one of those games where i'll leave it alone for a while, then come back and go through it once more. Then once the repetetiveness hits me again, i'll stop playing, only to come back once again a few weeks later. Then the proccess will just repeat itself for a long while.
So while it is tad repetetive, and a bit of a dissapointment, it is still an incredibely fun game. In short, I liked it.
