Pros:

- Nice RE atmosphere
- True to the movie
- Soundtrack
- Intense finale (the countdown)

Cons:

- Levels too easy and short
- Lack of SI (some more Tanks would be challenging!)

Conclusion:

Enjoyable to play with friends on Expert, specially if you are a RE fan.

Pros:

Perfectly done maps
Good navs for bots
Great ending (many possibilities to defend yourself)  
A good challenge to play on Expert with friends.

Cons:

None!

Conclusion:

A have to have campaign!

Pros:

Good textures and cool pathways to follow.
Guns and supplies in general.
Nice ending.
I liked the scenarios!

Cons:

We played in Advanced and was a little easy to beat. Maybe a few more Tanks with the panic events...
It is a regular campaign (nothing special to do!)

Conclusion:

Good campaign to play for fun with friends.

Pros:

Much harder than the previous version, with new spawn points, making impossible to defend only in the front gate (forget about do it with bots for more than 8 mins!)!!!

Cons:

None!

Conclusion:

Still awesome!

Pros:

Nice Chinese scenario!

Cons:

Just as a suggestion: turn the environment foggy in the city; put a hard rain in the wall; more Smoker on the top of the buildings and 2 Tanks in the 2nd map (inside the Chinese temple) will be challenging!

Conclusion:

A good campaign to play on Adv or Expert with friends.

Pros:

Is a short but well elaborated campaign (sometimes you want one for fun).
Lots of rooms to explore.
Balanced special infected and panic events/buttons.
Balanced supplies and weapons.
Nice atmosphere.
(Some) alternative pathways.

Cons:

I've got some pink textures (those sand barricades on picture 4).
We died once on map 2. When restarted, we were able to do at least half map with no zombies (differently than the first time)!

Conclusion:

Despite the Cons, is a cool campaign to play on Adv or Expert. I am keeping it! :)

Pros:

Hell yeah of a campaign!!!

Cons:

None!!!

Conclusion:

The craziest ending EVER!!! Epic!!!

Pros:

- Nice playtime!
- Nice work.

Cons:

- Too short.
- Easy!

Conclusion:

Since is same as the original No Mercy (but in daytime, instead), no news!
