Pros:

Excellent length
Very realistic details.
Multiple paths. Not linear.
Challenging without being ridiculous.
Encourages teamwork.
Good story.

Cons:

Not easily played with bots.

Conclusion:

This has been a wonderful campaign to play with my friends. I don't reccomend this if you're playing with bot teamates unless you are very familiar with the map and events. The atmosphere is perfect and the details are impressive. Keep up the good work!
