I played this map and it is fun.
What i would critizize is the lack of freedom and that it is therefore quite easy. What i mean is that you have no choice than to go the given ways, destroying generators to open iron gates. And that repeatedly. There is no feeling of fear since you can´t take the wrong passage and run out of ammo in the middle of nowhere. Therefore this is a well made map, providing fun for about an hour, but up to now with no need to play it again.
