To Get Regice, there are 2 way, either Get an event Regigigas, which is very unlikely now that the events are over, and even if you did i don't know exactly how to do it that way. Or play Through pokemon Sapphire/Ruby/Emerald And complete a VERY complicated side quest. which i did. The directions to the side quest are as follows exactly: http://www.wikihow.com/Get-the-Three-Regis-in-Pokemon-Emerald
Then import the pokes to platnium using pal-park.
Ace Trainer-Crisis
P.S. once you do, you can take the three regis to snow point temple in platnium and get regigigas, at lvl 1 no less.
You can only catch it in Ruby, Sapphire or Emerald and migrate it over. If you get an event Regigigas on Pokemon Platinum you can catch Regice there.
the only way you can get regice in heart gold is by trading from Pokemon platinum,diamond and pearl
In one of the empty caves just check everywhere
you cannot catch any regis in platinum you have to migrate them or trade for them but if you get regirock, regice, and registeel on platinum then you will be able to catch regigagas at level1 in the snow temple
yes but only through the special Nintendo event
Yes, that is the only way.
No; you cannot catch the three Regis in Platinum, UNLESS you have obtained a special Regigigas through some special events.
Regice can be captured in Mt. Coronet in the Iceberg Ruins.
you need REGIROCK, REGICE, AND REGISTEEL.
You can't because regigigas is a 4th gen pokemon. If you want a regigigas then you will have to migrate Regice, registeel and regirock to Diamond, Platinum or pearl
Do you mean Regigigas? If so, then you first need to attain all 3 of the regis (Regirock, Regice, and Registeel) then you can interact with the pokemon, and battle it.
you catch one
