Pros:

-Difficult
-Lots of fun with friends who know how to aim

Cons:

-Ugly
-Repetitive
-Pushing any button gets you punished
-Finale is broken
-A map entirely based on grabbing fresh M60's to kill tanks with so many throwables and items that it's really just a boring marathon that's only difficult if you're rushing like a bum
-Confusingly structured

Conclusion:

The way this map is put together is possibly very neat. But everything else about it is downright bad. It's not that it's too difficult, it's that the difficulty is piled on so high that you need T2's and M60's to get passed it, then it becomes laborious rather than difficult, as all you can do is trudge through the map holding M1 and S every time a tank spawns. Throwables a plenty so there's no reason to be afraid of the horde, but again it just become monotonous and boring. And the finale is completely broken. You fight the two finale tanks before you can hit the finale button. Not sure how any of that is SUPPOSED to work, but when you do hit the button it says rescue is coming but the door to the train never opens making all the monotonous effort we went through to complete the game pointless, thus resulting in a 1/10
