Pros:

Can't think of any

Cons:

Boring, nothing like the game it is trying to emulate.

Conclusion:

Worst map I've ever played. No relation to "plants vs zombies" whatsoever.

Pros:

Fun concept.
Brilliantly implemented.

Cons:

Impossible to play.
Hard to figure out weapons.

Conclusion:

I give it a 10/10 because I personally found it a bit hard to play, but only because I didn't plan on learning this map for hours to play it correctly.

Pros:

Lots of puzzles, fun, challenging, team-work oriented

Cons:

None

Conclusion:

Great map for team work, puzzles, etc. My favorite custom map for this game.

Pros:

*Unlock weapons and items through the "control panel" (first picture)
*Build chain link fence, k-rails (4' sections), a huge truck, some info kiosks, mounted .50,
*The fence around the rocket provides a very useful guard from zombies, and helps slow them down
*You can shoot and shove while unlocking/building stuff

Cons:

*no need to leave the rocket area
*simply spam bile to get rid of normal zombies
*you can shoot and shove while unlocking/building
*bots won't follow you into the rocket

Conclusion:

~would be nice to have a completely sealed room with locking door
~better rocket would be nice (looks like it was built with scrap metal and isn't even real)
~more options to build things
~adjustable time for unlocks/building (easy mode should be instant or 5 seconds each, hard would be 20 seconds, etc)
~option to move buildings
~option to play as infected in an 8 player game

~You will have to WAIT till the buildings are visible to let go of E (or whatever your "use" key is)
~"-Technology doesnt clearly spawn" - You unlock items and then equip them - they don't "spawn"
~played 5 times, no bugs in any rounds
~The new/updated version of this, is a better concept, but the control room has almost no protection and to get to the rocket area, is practically a mission in itself. I don't know if the same person worked on that map, but I definitely feel this game mode/concept has great potential.
