Some weeks ago I bought by Steam a copy of Gratuitous Tank Battles.
I just bought from Gamersgate Gratuitous Tank Battles The Western Front Expansion.
At the positech website I found a page where you can have the steam key of the product if you insert the product key.
I guessed that I will be able to get a Steam key for the add on, but I was wrong
I just downloaded Gratuitous Tank Battles The Western Front Expansion but I didn’t find any product key there or on the purchase order mail I received.
I opened a ticket with Gamergate but they replied that "The GG versions of this product is DRM free and do not have , or need, serials."
Can you be of some help?
