Pros:

nice long maps
well detailed 
nice balance of ammo
creative use of props and barricades
fun gameplay
easy to follow
wall/math puzzle

Cons:

invisible walls not needed
lack of proper cutscene for the getaway
i got sand in various places ;) (j/k keep it!)

Conclusion:

A fun short campaign (4maps) but i highly recommend downloading this!

i like military mods like this: well thought out, well planned and well executed.

The run from start to finish was just long enough and exciting enough to keep the player in suspense and wondering what's around that next corner.

The finale battle was... let's put it this way, colorful hehehe nice bit of coding there. first time i've seen this in a mod.

took away some points b/c it coulda used some more ammo at the end, it wasn't so much that it was difficult, but more that there were so many hordes at once, which i love of course but i kept running low on ammo through out the whole campaign, and that isn't part of my plan. Maybe some goodies strewn about the finale cave could balance that, gas cans, pipe bombs, mols around "the object". 

if you make this for l4d2 i definitely want to see melee weapons and grenade launcher near wide open spaces (sand) and the M60. it would go well with the decor, hehe

When the battle was over, it seems as if it needed something to commemorate the ending, maybe some explosions, or a rescue as an end cutscene, i think it deserves that.

I took away some points for a couple invisiwals that shouldn't be there (map1 cars and house) and if you add a tad more ammo/goodies at the finale battle, it could reach 100 and i don't say this often. 

But all in all it's a great mod, Kudos Kev Edwards, i give it a 95.

This is one that goes in my watchlist. A definite download for everyone !!

Pros:

++ fun long levels
++ great weather effects
++ wide open varied terrain (doesn't get boring!)
++ great fun with friends

Cons:

needs more spawn closets
i wish i could go on the train tracks hehe

Conclusion:

i liked the long levels i felt immersed like in the original campaigns, it can be hard to find spawn closets in nature but more shacks, sheds, etc can be used, even a kids treehouse could be used for that.

i love the suspended bridge & the swamp level. The mobiles homes level and cemetery are fun and have great weather effects all around. The daylight maps are well done, i get weary of dark maps. 

And yes the last level can be hard to finish for some, so i'd put some adrenalines to speed walking in the water, but all finales should be hard.

its a fixture in my lan parties and permanently in my watchlist. 

A well recommended download ! 2 thumbs up !
