orcishgamer: That's great and all, but it was intended to be nearly a MMO and there's no servers for it right now (unless there's a pirate server scene, no idea). I'm not saying don't recommend it, just you should add the caveat that part of the game isn't there due to the servers being gone.
michaelleung: Actually, I believe a South Korean company has bailed out the game and they are slowly setting up servers in the US and Europe.
I didn't know that, though I knew Flagship had their IP owned by a half dozen creditors or more when they folded. A bank ended up with their MMO code, iirc, and had to hire a shop somewhere in Asia to start working on it.
I guess that puts it in APB territory, it might get a lifejacket. If it ever does, there will be digital copies available. I don't know, I didn't think much of the game itself, I was in beta, they launched very broken to the songs of their fanboys. I watched the news a bit as Roper's reality distortion field slowly collapsed (what a tool that guy is!) and the assholes preaching about how they were so great watched their founder's editions go up in smoke.
Did they even patch all the gamebreaking issues? I don't actually think they did, monsters teleported around, instead of animating they just kind of quivered in front of you, hovered in the air or under the ground. You'd go into a randomly generated dungeon and walked through the exact, same room 6 times in a row, the list of problems with this game was legion.
At any rate, given what state the game is currently in a small caveat is always worthwhile, "Hellgate: London is X, note the official servers are down and there's some unpatched bugs, but the community is still active" kind of thing. If people just go by the hype (and this game had a ton of it, they might be misled.
Also, as usual, PA to the rescue:
