If you missed the opportunity to get level-100 Arceus via GameStop earlier this year, you now have another chance to receive the Mythical Pokemon. It can be yours by entering the following code in Pokemon X, Y, Omega Ruby or Alpha Sapphire by December 31: ARCEUS20. It is equipped with the Multitype ability and four moves – Judgement, Recover, Hyper Beam and Perish Song. Keep in mind that if you did receive Arceus at GameStop, you won’t be able to receive another one.
