Pros
+ Simple design, without the need to overcomplicate.
+ Simple defence concept.
+ Puts the meaning in a survival game.
Cons
- Perhaps a bit too small and limiting.
- Graphics somewhat lacking, but a minor detail if you are just looking for something to shoot.
- Slightly difficult to camp, which may be how many people do survival.
Not bad, but I wouldn't say fantastic. It's simple, but also lacking in elegance somewhat, for example, I really don't like the black sky - add some grey or blue or similar. Admittedly, I like the map, but I'm more likely to end up playing the 'Helm's Deep' survival.
