Also:
I have a "Frozen Synapse Multiplayer Key" different from the one I'm giving away above. My understanding is that it does NOT serve any purpose, since apparently there is no need for multiplayer keys anymore. However, you are free to give it a try in Steam or whatever. If you are interested in the game and didn't win the giveaway, feel free to comment here. I'll give said key away to the first commenter (if any) that expresses an interest in it after the end of the giveaway.

Hello. I would like to ask you. maybe you know, the keys to this game from HB give two copies like a purchase on steam, or just one copy? I would like to play with a friend, so I don't want to take away the chance from other interested, if it activates only one copy per account.

The giveaway has ended so it doesn't matter much but... I don't really know, sorry.
