Pros:

An original idea. 
Legos! 
Most of the weapons.

Cons:

Very small.
A few camping spots where it is almost impossible to die.
A lot of glitches. 

Conclusion:

A fun design that could have been a lot better then it ends up being. It's very easy because of certain camping spots, but is still a fun map to play if you don't exploit these or the several existing glitches.

Pros:

A Lego campaign!
No big glitches. 
Good amount of zombies most of the time.
Good length.

Cons:

A little to easy at some points.
Incomplete.

Conclusion:

Awesome idea even thought it's not entirely original. Although it is not finished, it was very enjoyable to play. One idea would be to mod the weapons to look lego built, though I admit I haven't used the modding tools for this game yet, so I don't really know how difficult that would be. All in all, keep up the good work.
