This guide will help you to make the first steps in the IL-2 Sturmovik: Battle of Stalingrad project - from key activation to first flight and aerial combat experience.
Game and DLC Key Activation
1) Start the game from Steam. You'll notice a pop up message with CD-key - copy it to clipboard because we'll need it to activate your game copy at
On the login screen click NEW USER REGISTRATION if you don't have an IL2BOS account yet.

2) Register an account using your personal email and a secure password. You may also use Google+ or Facebook credentials to speed up the process.

3) Confirm registration and login into your account.

4) Enter a desired nickname and a squad tag, if you have one. You can change it anytime.

5) Open LICENSE KEYS tab. You'll see a small window for the IL2BOS key that you've purchased on Steam.

6) Switch back to Steam app window, open LIBRARY and copy the CD-key for IL2BOS.

7) Paste your key into the KEY ACTIVATION blank field. If you've purchased Digital DeLuxe version, then activate you core game key first, then add codes for the DLC planes.

8) Congratulations! You've completed activation. Now you can play IL-2 Sturmovik: Battle of Stalingrad!

i keep getting license key not activated and it's never happened before and i can't find the cd-key cause there isn't anything called that in my steam library and I've played the game before without any problems, i could really use some help cause i can't get a refund it's too late for that and i don't want to waste €93,98

What about the opposite way around? Say I was to want to purcase Battle of Kuban and then activate it on steam? Anyone know?

I just activated the game and had to create a Il2 account in the process. E-mail came almost instantly. Activated. No issues here.

The website never sent an email link to activate an account. It has been 2 days since purchase and I cannot enter a key anywhere to activate the game. I created an account but when I try to login it reports "this account is inactive." Still waiting on that activation email.
