Pros:

+ Nice idea, let's build a car from scratch
+ Huge map
+ Fun if there are players
+ Fence building is a nice element of the map

Cons:

- Bots can get stuck in fences
- No story (How did they get there? Where will they leave?)
- A bit empty map (too much empty space)
- You can attack while building fences/car etc.
- When you turn on the generator, when are the lights come from? The light generators look like they are turned off
- Annoying grammar errors (secondes instead of seconds, medikit instead of medkit etc.)

Conclusion:

Nice map, and it would be better, if you make it a whole campaign, and this map should be the finale
