4 Gamer was able to talk with 2 of the developers of Frame City Killer for Xbox360. The game fills the entire DVD9 disc apparently, and as you know, it uses the Unreal 3.0 engine. The real interesting part is that at one point in the article they mention the fact that players will get a new mission on Xbox Live every week for a year after the game’s release. You will need the babelfish for this one.
KK: Actually, for Frame City, we are going to offer a mission every week for a year on Xbox Live. Yes it’s very hard for us (laughs) But, it makes sense if you think about the life cycle as a game software. There are opinions like “don’t do network distribution like that, put them all onto a disc media for sale”, but if we deliver it periodically via network we can enable users to play a game longer. Also my hunch is that the distance between us and users gets closer if we can offer a new content and let them play it immediately.
