This should come as no surprise to those who followed the Japanese launch of Pokémon Mystery Dungeon: Gates to Infinity, but it's still good news for North American fans. When the dungeon-crawler launches on 3DS in the west, it'll come alongside DLC that's free of charge for a limited time.
The Poké Forest Mystery Dungeon is the first item, and you'll be able to download it for free between March 24 and April 30. Three additional dungeons will also be released at launch, but they'll cost ya. Nintendo plans to release Mystery Dungeon DLC on a regular basis.
The official site is also now live.
For a look at some of the DLC that's already arrived in Japan, check out one of our previous posts. Pokémon Mystery Dungeon arrives on 3DS in North America on March 24.
