This narrative campaign is designed to immerse you as completely as possible in the role of Captain Evans, commander of C Company, 1st Battalion, 508th Parachute Infantry Regiment. Your company is destined to play a pivotal role in the 82nd Airborne’s seizure of Sainte-Mére-Èglise on D-Day.
This fictional but historically plausible campaign infludes:
-Four possible branches, depending on the player’s choices
-A complete campaign narrative with memorable characters and real command choices
-Six combat missions (no pun intended) that run the gamut of the 82nd’s operations on the morning of D-Day
IMPORTANT WARNING: THE CHARACTERS IN THE NARRATIVE ARE BASED ON REAL-LIFE INDIVIDUALS. MANY OF THESE INDIVIDUALS SWEAR LIKE SAILORS, THEREFORE, SO DO THE CHARACTERS IN THE NARRATIVE THAT ARE BASED ON THEM. THE LANGUAGE IS DECIDEDLY M-RATED, AND IF YOU THINK THIS WILL BE A PROBLEM I SUGGEST YOU AVOID READING THE NARRATIVE.

I rated this 5 stars, because it’s probably the best user-made campaign so far (at least the best I’ve played). However, the last mission spoils it a bit. It’s too easy to just shoot up the German rush against your position.
This is still my favourite CM campaign ever.
Devil’s Descent is a fictional, tiny airborne infantry narrative campaign, focusing on a single company. Managing your troops and their ammunition is of prime importance, and the scale means that you can get to know your troops and the terrain. The short length means that the campaign can be completed in a short period of time.
Do I need to buy any DLC for this campaign or is it possible to have the base game only?
I played through the campaign and i have to say, its a nice touch to fought with a relatively small Company. However, the Campaign is far to easy and can be cheesed on several mission. In the first mission, i may got a bit lucky, but i dont lost a single soldier, not even one got wounded. And that happened for me in three missions overall. i had a higher number of casualties in just one mission, which was caused by a very dumb move of me.
In the ambush mission, when the stugs spawn, i can position my bazookas right next to the spawn point. easy kills, no losses at all. Also one mission is more or less recycled.
Combat Mission is fun every time, but to be honest, i expected a bit more
