On the whole, it is a well-compiled, but dull and uninteresting map, which offers little in terms of gameplay. When I first ran this map off-line I was impressed by the architecture and the lighting, but disappointed at how small it was. Then I had the chance to play Sludge1 in Team Play and it rocked. In team-play the limited size worked to it's advantage. But you have to think fast.
Most areas have at least two access points, making a camping defense a dangerous option.
And hunting down that last wounded survivor is quick and dangerous. Like Jungle1, the outcome is usually decided by how The Team uses the geography, rather than who is the best shot with the biggest gun. The nice thing about the geography here is that a static defense is useless if your team isn't pressing an attack somewhere else. As others have mentioned, snipers will hate this one since, for the most part, lines of sight are short. But if you appreciate tactics and mobility, this level races.
