Martin Loxton is the man who saw Oblivion for what it was — a completely unpopulated MMORPG — and started hacking into memory to let more than one player play in Oblivion's drab, lifeless world. He's a resourceful guy and he's granted Firing Squad a small interview about what went into hacking Oblivion into MultiTES4:

FiringSquad: How difficult was it to create the mod, especially since the game is designed for a single player experience?

Martin Loxton: I hadn't attempted anything of this nature before, so it was one massive learning experience, and it took a lot of research to say the least. The multiplayer component isn't too complicated; it's just a matter of sending and receiving data between a client and server. The tricky part is the injection and extraction of data in memory. You need to be able to find where Oblivion holds its information in memory, and then modify it to reflect a multiplayer environment. Certainly not the easiest thing I've ever done.

We think Loxton's swell, but we'd be more likely to play Oblivion multiplayer if the game wasn't just one gigantic fart bubble from the collective bowels of fantasy cliche. Florian Eckhardt
