Initially, the game had a heavy anime style and Joanna Dark received many alterations throughout the development process. Lead Art Director Wil Overton explained that they "wanted to bring her back in line with the way Rare do things. [...] We sorta wanted to stylize her up a bit and make her more iconic". However, the designers ultimately decided to tone down the styling of the game a bit. The Xbox 360 gave the developers more possibilities to include what they always wanted and allowed them to create the game's co-operative mode, which was one of the first that could be played via Xbox Live. Designing the co-operative mode over Xbox Live was very challenging for the developers. According to Duncan Botwood, who was responsible for most of the multiplayer, "it was quite an effort to put it in, to be honest. You have to cater for a number of eventualities you just don't get normally. We think we pulled it off, and because we pulled it off, other people might feel inspired to put the effort in, and we think that's a good thing".
