Pros:

+ Nice introduction!
+ Design of the levels isn't that bad, I liked the idea of the traps
+ Golden Gnome :D
+ Cliffside was a great scare! Chargers gave me a heart attack
+ Scanner system was nice, and putting the gnome in the pedestal also played out well.
+ Custom Boss as well as custom side bosses + take was great! Another target to shoot at besides the tank.

Cons:

- Missing textures when you put the gnome in and on the device that scans you
- If you die you're F*CKED because you have to start from the beginning.
- If teammates die during the finale, they spawn in the outhouse, and then somehow the bot teleports over and helps them out, then teleports back
- Need warning about the traps in the forest, wasn't obvious on my first playthrough. I died and raged. :(
- Chopper (see conclusion)
- The invisible wall at the beginning was sort of a let down because honestly the only thing that should block your path is a cliff wall. You should just take that out.

Conclusion:

Overall it played out to be a nice single map campaign. Though I'm not sure if I'd like a safehouse somewhere, because if you die in the finale, your F*CKED. The idea that the chopper was burning the more rounds you survived with it, but I didn't feel like I was accomplishing anything by shooting at it. The idea of having side targets (military men) was nice when the tank came, and the Golden Gnome and putting it in the pedistal was godly.

For that part, I thought maybe it would be interesting if you had to find the gnome, and then put it in the pedistal, instead of having the gnome right there, but thats just a thought.

OVERALL
79/100
Nice, but some errors, missing textures, as well as dying and having to start from the beginning, but I can see a lot more potential if you were to fix the errors. The gnome was nice, but the event happened too quickly and felt a little useless in my opinion.
