GS: The initial announcement of Bloodmoon mentioned that players can either fight menacing werewolves or actually join the werewolf ranks. How do you become a werewolf? What will the game be like for characters who become shape-shifters?

AC: What I love best about Bloodmoon is that you actually can role-play as a werewolf. You live this secret life at night--no one knows how powerful you truly are. You start to keep very careful track of the time of day. When you're escorting people, you think to yourself: What if they see me change and find out the truth about me? What if we don't make it to our destination before nightfall and I have to kill them to quench my blood lust?

To keep it easy to understand, we used the vampire model from Morrowind--if you catch sanies lupinus from a werewolf and wait three days, you're a werewolf. It can be cured with a simple cure disease potion, but if you don't cure it you'll get a fevered dream on the third night. After the dream, you'll immediately wake up and you'll find your clothing stripped away and you'll feel an overwhelming thirst for blood that must be quenched.

Every hour that passes, if you do not kill an NPC, you'll lose a percentage of health. You'll never die, but if you do not feed, a substantial amount of health will be gone when you change back to human in the morning.

We first focused on making the werewolf fun. You are a killing machine. You growl and snarl as your claws rip through creatures and NPCs. You'll howl at the moon after making a kill.​
