Anyway here's the rules, yo.
The official rules of the Adepticon Battle Force Contest:
If you purchase a drink (we prefer alcohol, but regular drinks are welcome) for a member of the Dark Future Games Staff wearing a shirt with the image above, you will earn an entry in our raffle for a battle force of the winners choosing (or an equal value in GW merch - current stuff only).
There is no limit to the amount of times a person can enter. (yes, you can buy us a case of beer too and receive an entry for each one!)
A member of DFG may not refuse the drink and must enter your name. If he is taking part in an event, he may pass the drink to a member who is not playing.
Will will choose the winner the Monday following Adepticon and mail out the prize as soon as we get our hands on what the winner wants!
So if you see these guys go ahead and buy them a drink. I know I will!
