Pros:

Good Length (5 maps)
Great Level Design
Easy to Navigate
Balanced Difficulty

Cons:

Some may have trouble finding Finale switch
Loading screen names mixed up
Bot died/trapped on the final elavator

Conclusion:

A very good all round campaign, the finale was well above par; the machine-gun turret was actually useful for once and worth using. I would highly recommend this campagin to anyone as it is almost on standard with a Valve campagin :)
