Pros:

Half Life 2 episode 1
Music form the game and trailer
Half Life zombies (but just stand still and attr=ack if you're in front of them)
Practically a perfect port of a couple of maps to L4D
Has a Gauntlet crescendo (which is in L4D2) 

Cons:

None

Conclusion:

It's fun to play L4D in a Half Life world. Full of zombies, but no Gordan Freeman here.

Pros:

It's Luigi
Model looks great

Cons:

Conclusion:

Looks good. Has his own picture in the character screen. Fun to murder zombies as the green plumber.

Pros:

Minecraft
Crafting
minecraft graphics

Cons:

none

Conclusion:

A minecraft world full of zombies, oh what fun. I love how it has the same looks of Minecraft and even has crafting, CRAFTING! One of the best maps for l4d

Pros:

Cool to see Mario characters.
Works perfect with the sound mod and Mario survivors

Cons:

No such thing

Conclusion:

Great work on the models, as I said you should also get the sound mod, it really makes it seem like a boo is riding you and Donkey Kong is charging you etc. 

Pros:

Amazing port from Oot
Music is also ported
Puzzles almost exactly like the ones in Oot
Boss is pretty funny

Cons:

Bots can easily get killed getting the Kokiri Sword, and in the falling ceiling room

Conclusion:

If you love Oot than this map is a must have for this game. Both of your maps form Oot are excellent. Some of the best ever. Keep up the good work my friend.

Pros:

Works perfect with the infected mod
Music is great
Boswer fights in Dark Carnival finale  have special music that is epic.

Cons:

None

Conclusion:

If you have the Mario Infected mod or not, this is a great addon for the game.

Pros:

Exactly like the Oot version
Music just like it too (brings back that Nostalgic feel)
Cool custom melee weapons
Great Easter eggs (like a King of Red Lions boat from WW)
Boss, mini-boss, and kesse from Oot

Cons:

Fourth level sometimes crashes

Conclusion:

Great port of the Oot level, very challenging, great innovation. Recommend to everyone using the site. Wonder if you'll make the Water Temple next (that would be the hardest map ever since it was extremely annoying in Oot).
