First, boot up the game on your mobile device.












Just press start and you will see the character selection screen! Press the cloud at the bottom left of your screen.

Now, you should see a screen looking like this,
press the STEAM LINK button that you should see below









Make sure your connected to Facebook or an email before attempting to link accounts You should see your code for your account, now you have to get into steam (registeran account if needed and download the client).

Now, make sure you leave that code you just got up. Install the game if you haven't already by going on the steam store and looking up SAS: Zombie Assault 4

Make sure theres enough space to download and install the game (344mb) and click play! You will see the same screen as you did before on mobile when started up.
Press start and you will come to a screen like its a completely new account, but don't worry! This is where your code comes in handy. Press the cloud button.

Press the cloud button and you will get a prompt asking if you have played on mobile. Click yes and then enter your code from before (for example my code from the screenshot earlier was TYLUC-XVMH).


Enter code here

Now you have succussfully linked your steam and mobile account together! All your weapons are here!!! :D
