Pros:

- Low gravity in out side areas
- Information, Barricades, and Upgrades are unlocked
- Variety in barricades
- Two seprate unlock panels
- 3D Ship model over building area
- Futuristic outter space enviroment

Cons:

- Many tanks
- Some barricades do not slow down zombies much

Conclusion:

A very good map, it is challenging but not too difficult. It has features that are not in other custom maps, and the enviroment really adds to the game play experience. 

Pros:

- Steps required to progress
- Power can be turned on to add light
- Good map for beginners 
- Weapons room is very safe
- Easy to navigate
- Bots protect well

Cons:

- Map excessively big
- A lack of zombies for the map size makes the large amount of barricades unneccisary
- Very few special infected
- Some weapons do not highlight when unlocked
- Bad grammar
- No autoturret to be found
- Perspective camera drifts away from the player during interactions
- Can be beaten in single player

Conclusion:

This map is a bit lacking in challenge, and there are quite a few technical bugs. The map is good for those who are new to Let's Build maps though as it is not excessively difficult or stressful.
