Guild Wars 2

" It will feature 9 mini-dungeons that will be randomly assigned to players that attempt it"

Is it just me or does this sound like it is a solo dungeon????

Fractals of the Mists

ArenaNet’s Colin Johanson briefly introduced the brand-new dungeon as one that gets more challenging the farther in you go. Conventional wisdom would suggest that that’s nearly always the case, but Johanson left out a key detail: In the Fractals of the Mists dungeon, you can go indefinitely farther in.

The Fractals of the Mists is made up of nine mini-dungeons, each with its own story and environment. A party of five will enter the dungeon and be faced with a random set of three of these dungeons at a time. Upon completing those three, the party will be transported to a hub to rest, repair, and merch — and the difficulty scale for the dungeon will be raised. Every time the difficulty scale is at an even number, players will face a special boss encounter.

With great challenges come great rewards. The patch will introduce ascended items. Ascended armors are “slightly more powerful than exotics” and can, in some cases, hold slots for infusions. Infusions will allow you to increase your character’s power. Guild Wars players are familiar with infusing armor, although I’ll be my hat that the process doesn’t involve creepy Seers this time ’round.

It sounds to me like your party will be randomly assigned say 3 (as an example) from a pool of 9 which merge together to give the one dungeon. I Guess it just adds some variety than running the same path over and over. 504 combinations or whatever it is (providing order doesn’t matter).

well, its just that the screen shot on the wiki shows one person in one of the dungeons….

Pretty sure its a 5 player dungeon.
