Pros:

-Fun and creative concept
-unlocking technology forces players to have prioritys.
-teamwork IS required
-who doesnt want to build a rocket?

Cons:

-Technology doesnt clearly spawn
-bots dont use technology
-most building items are useless

Conclusion:

I thought it was decent and i like to play it numerous times, but the game became rustrating when none of the tech would spawn and i had to resort to the basic pistol. The barriers at the door help a little bit but mostly get in the way when special infected arrive. objects like the kiosk and the crates are useless and a waste of time, especially since the tech is buggy. If the tech bug occurs i had to restart the map in hopes that it wouldnt happen again. Overall the map could still use a litte tweaking but it is still fun to play at times.
