Pros:

+ Name change and GUI icons on the characters

+ No axe-glitch (if there is, I didn't see it)

+ The details, for example on Meiko's arm-warmers (or whatever it's called :P)

Cons:

- Meiko's forearms show through the aforementioned arm-warmers when she's holding primary weapons like autoshotgun, but I don't mind

Conclusion:

If you like Vocaloid or anime, you should download this mod. I haven't experienced any bugs or glitches with this mod, so gameplay-wise it's perfect.

Pros:

- The puzzles are good, not too repetitive or boring

- Challenges us to think on our feet as the hordes keep coming

- The levels are interesting

- Slow motion effects make for good laughs especially when seeing a Tank punt someone away :P

Cons:

- On that level where you have to jump out of a hole in the wall, both my friend and I hung on the ledge while trying to jump, whereas the bots just jumped and then got Smokered

- I never understood the inclusion of 2 cola cartons (in the room with many gnomes); I thought that was somehow pivotal to the conclusion of the story, so I carried it to the end (I guess that means the Survivors get to celebrate their escape with some Cola?)

Conclusion:

A refreshing change from the usual style of maps that are purely "go from Point A to Point B". This is a great map, especially for people who love puzzles but do not like excessively huge (and similar-looking/disorienting) levels.

I give it a 98; the cola isn't a big deal but the annoying "hang from the ledge" at the hole in the wall can cause a lot of problems, especially if there are no AI players to teleport up there and save you.

Pros:

Looks just like Garrus
Attention to detail
Animations work well
Lobby and team icons are changed

Cons:

First person is still Ellis
Garrus' mouth does not move (but it'd take quite a lot of work to fix that, so no worries)

Conclusion:

Ever since I downloaded this mod, I haven't changed it for any other Ellis replacement. Go Garrus!

Pros:

Lovely skin, works and looks great. There was another mod for L4D1's Zoey that has leather, but the shine was too overdone. This one has just the right amount of shine. :)

Cons:

None that I can find.

Conclusion:

Great mod for leather-lovers :)

Pros:

You can hear other Special Infected more easily now when you're using the chainsaw.

Cons:

None that I can find.

Conclusion:

A great mod for people who like to use the chainsaw, or who have friends who do. :P

Even if you don't usually use the chainsaw, this mod is handy. You never know when someone decides "Hey, I'm gonna use the chainsaw riiiight next to my teammates".
