you tracked it down doesn't hurt either."

Beat the Champion to gain access to Snowpoint Temple.

Obtain the National Pokedex.

Open the Pal Park.

Transfer Regirock, Registeel, and Regice from Pokémon Ruby, Sapphire, or Emerald into your Pokémon Platinum game.

Alternatively, if you have a special event Regigigas, capture the three Sinnoh Regis (Regirock, Registeel, Regice) and have them in your party.

Enter Snowpoint Temple. The first floor is straightforward.

Navigate the subsequent floors using the following directions:

• Floor 2: From the staircase exit, go 5 steps down, 5 steps right (on the 4th step, you slide, then take 1 more step to the edge of the next ice patch), 2 steps down, 1 step right (to go on ice and slide to the end). Then go up the stairs.

Floor 3: From the staircase exit, go all the way left to the wall, then all the way down. Take 2 steps right, 4 steps up, 2 steps right, 4 steps down. Go all the way right, then go 3 steps left, 1 step down, 2 steps left, 3 steps up, 1 step left, 1 step down. Then go to the right over the ice and down the stairs.

Floor 4: From the staircase exit, go 3 steps left, then go all the way down (slide on the ice). Go left 1 space then go up (ice will slide you until you hit the rock). Go right (ice will slide you until you hit the rock), and then go up (ice will slide you until you land). Finally, go downstairs.

Floor 5: From the staircase exit, the staircase is on the top right.

Floor 6: From the staircase exit, go 1 step left, then go down (slide on ice). You should now be on a patch of regular land; from there, take 1 step down, and you will be stopped by the rock. Go right (until stopped by the rock), go up (you should be on another patch of regular land). Then go left (until stopped by a rock), then down (until stopped by a rock). Go right (until stopped by the rock). Finally, go up to face Regigigas.

Before battling Regigigas, ensure all three Regis are in your party. Save your game.
