Pros:

Very varied environnement

Very fun to play

Nice ending

CANADA FTW! (lol)

Cons:

Some areas are really confusing, and zombies spawn in places i cannot reach (sometimes)

In the port level, i got pulled under a boat by a smoker... thats also an exemple of the other cons.

Conclusion:

This campaign is really fun, but sometimes very confusing. Im sure i would enjoy playing through it with my friends.

In short, AWESOME CAMPAIGN!
