You had to buy the potato pack and earn the potatos in the games, i already owned most of them so it cost me a <£10 to patch up the gaps.
I earned the potatos (34 from games, 1 from joining a group, 1 from getting the rest), that give you the golden one.
I bought portal 2 (preorder) before hand in a 2pack, but thats not a requirement, because i didn't own portal 2 i got the giftable copy, same applies to all other valve games. (you also got a tf2 and portal hat and a portal 2 coop skin for the potato pack)
Yes, i said portal 2 hat................
