Q: How “massive” is the multiplayer online world for Hellgate: London? How many players will I get to interact with at one time?
A: The number of players you interact with depends on where you are in the world and what you are doing. You can be a solo adventurer or play in a party of up to five members. You can also maintain larger circles of friends and guild mates, mingling with anywhere from dozens to hundreds of characters in the largest Underground stations. You can also interact with tens of thousands of players via auction houses and worldwide social structures.
Auction Houses är således implementerade!
