Great design
Secret area
Some superb sections with great atmosphere
Challenging
Good length campaign

Can be really difficult (not necessarily a con), so having a good team really matters

An excellent campaign, totally recommended 

Pros:

Looks great- animations and textures
Sounds great
Perspective is spot on
It's different
It was in Wolfenstein

The ironsight isn't perfect, but it took me a while to notice, its a tiny con

Excellent, I always use this or the FN FAL mod for the AK
