Pros:

- One of the many custom campaigns that is set in another country. I've seen many great add-ons, and this is one of them.

- The campaign is more fun with multiplayer.

- Nice winter environment.

- The rescue chapter takes a creative way for players to enable an escape route.

Cons:

- Difficulty with finding the right pathway during the Great Wall chapter on my first playthrough.

- The ice is a bit too slippery to me, I have to slow down when melting ice, but it's not all too bothersome. Players still need to set a distance because the fireworks as usual, burn them aside from the zombies. Running too fast on your feet also can get you to either slip at the edge of the ice hanging for dear life or drown to death in the water. Ouch!

- Missing asset: The skybox in the Great Plane chapter only shows pink and black checkerboards. It could be that said asset exists from any game I do not own, or the creator was a little rushed in the development of the campaign. Probably the former.

Conclusion:

Seeing that Wan Li is part of a previous contest, I could see why it was the winner (and deserved that), but there still are some flaws here and there. Nevertheless, I enjoyed my entire playthrough in the campaign. I really wish people out there have this and still play it.
