Here's a brief task list for people who want to move over to Steam:
1. Download and install Steam itself.
2. Go to the STORE menu option and search for Command Ops 2 - this is the core engine which is free. Download the core engine and run a game on it for a few minutes to make sure everything works.
You've now got steam and got Command Ops 2 loaded. The next job is to activate and download your existing CO2 games. To do this, you'll need to find and copy each game's Steam key. This is provided free to existing customers of CO2.
Here's what to do:
1. Minimise Steam and go to your Lock 'n Load store account.
2. Go to Order history
You'll see a list that summarises all your orders. In the column on the extreme right, you'll see a blue box with a white eye symbol on it. Click on the box to see your order in detail. When these details appear, you'll be able to see the Steam key associated with that order.
3. Copy the Steam key into something like the Notepad application in Windows, or you could even copy it down on a piece of paper if you're old-school.
4. Now go back to Steam and open the Games menu at the top left of the Window.
5. Select Activate a Product on Steam
6. Click Next. Scroll down through the agreement and then click Next.
7. Copy and paste the Steam key from notepad into the field. Or type in the Steam key from your peiece of paper!
8. Click Next. Look at the bottom of the screen and a download will begin. Once the download is complete, the game will appear in your Steam library, under Comand Ops 2
9. Play the game and enjoy the automatic upgrades that Steam runs for you.
