-good portal references
-fun at first

-bots hit all time AI low
-gets repetitive very fast
-problem with the file ( may be corrupt)
-the mazes are cheap
-finale isn't anything too special
-not really playable by-self

This map was a good idea, but as far as the playability goes it is far from. The bots are extremely dumb, the puzzles have very few variations between them and me and my friend downloaded this map at the same time and we both had issues for all of our in-game maps. There was no horde music at all, deleting the map from add-ons has resolved the problem, so i doubt its just a fluke. In my opinion the end of the map couldn't come soon enough...

Not very fun
Very confusing
too hard

Overall I wanted to kill myself in the first 5 minutes. Don't play if you hate puzzles. If you like puzzles you may play all you want.

-Nice Puzzle idea
-Well-made, no bugs and fair difficulty, fitting atmosphere

-Always the same puzzles (kinda)
-Epic botfails (was crossing the bridge over the acid, a bot following me kicked away the weight -.-)
-THEY ESCAPED! Shouldn't they have died or something ^^ :P

Not bad, but really short and even though being short, quickly repetetive... ntm nonsense tank and witch spawns...

70

cool idea
good finale
supports all game modes
fun puzzles
Tanks and witches

WAY too mazy. for example on chamber 8 it took me 20 mins. to find the necessary item to complete the puzzle

bots are idiots
takes forever

this was a fun map to play for a while, but got very tiring and was repetitive. witches were very effective and difficult to kill

- Great Portal immatation.
- Easy to understand puzzles.
- Fun to play with/ without friends.

- Gets repetitive.
- Too short.

Fun to play through repeatedly at times, but needs some work.

Variation on the PORTAL theme, albeit much, much darker.

New take on the infected survival concept.

Puzzles all consisted of 'locate this, set on switch (optionally, explode), move forward.'

Voice over of the computer system was a little hard to hear.

This was a pretty wicked map. I enjoyed it thoroughly, despite its repetitive nature. For a co-operative experiment, however, there really isn't much need for the players to co-operate beyond carrying multiple items to the button should one be destroyed. Regardless, I still had a fun time and will be playing this map again.

*Portal-like in many ways
*Puzzles are fun
*Option of brain or brawn in most parts.
*Difficulty grows steadily.
*Intelligent solutions
*Sequence breaking is allowed.
*GLaDOS's comments make the game very freaky.
*Great sniping points for versus Smokers.
*All in all, a great puzzle game with traces of first-person shooter, exactly like Portal.

*GLaDOS impression isn't perfect. Not at all.
*Idiot bots always ruin perfectly positioned bombs.
*Possibility to be trapped and die hopelessly.
*Finale needs work.
*Confusing layout, to the point of redundency.

Great for Portal, mediocre for Left 4 Dead. However, as I like both, seeing them mixed is always fun. I have never seen a Valve mashup since GMod YTP, but that is another story. Anyway, 9/10.
