Developers posted an invite code on the official FB site today for the NA servers. The invite brings new players 300 free gold, the T2 premium tank (750 gold to buy, 150,000 credits if you sell it) and 3 days of premium time. That’s about $10 of in-game content free, but for new accounts only.
To get the free gold, enter FBTANK when creating your account.
