You can only get it at the Hall of Origin in Platinum, a secret staircase on the Spear Pillar. Unfortunately, the event for Arceus is over, so you will have to use an Action Replay or something to get it!
There isn't one.
To get an Arceus in Soulsilver or Heartgold, you needed to download it at an event, otherwise you would have to use codes or trade from another game.
you need to order Pokemon heartgold and soulsilver when they come out
Trade from Pearl or HeartGold/SoulSilver (Arceus event)
i am sorry but you cannot obtain arceus in Pokemon heartgold or soulsilver.
Arceus has never been distributed as an egg. If you are referring to the egg from the HeartGold/SoulSilver Arceus event, it hatches automatically.
You dont get Arceus in HeartGold. You need to trade one from another HeartGold or SoulSilver or trade one from the Sinnoh region games. WARNIG: IF YOU HAVE AN ARCEUS ON BLACK OR WHITE YOU CAN NOT TRADE IT BACK TO THE JOHTO OR SINNOH GAMES.
you can't catch him, you have to wait for a special event.
You cannot catch Arceus in Pokemon Soulsilver nor Heartgold, You must either transfer a Arceus from D/P/Ptt or Receive one through the Arceus Event.
You need the movie arceus or a regular event arceus for heartgold or soulsilver
you cannot catch arceus but you can get it as a MYSTERY GIFT you from trading with DIAMOND/PEARL/PLATINUM.anyway i hope you enjoy your arceus.
Yes. Wait until HeartGold/SoulSilver is released, and catch it.
