Arc Angel is a cancelled futuristic racing game prototype that was in development in 2003 for the Xbox, by a team lead by Chris Seavor at Rare LTD. There are just a few info about this lost project as a nice article at Pure Rarity:
Chris said that for the record Conker 2 was never scrapped; he just didn’t want to do it at the time and that was how Arc Angel was conceived. A nice easy racing game, or so he thought. During the four months he headed it a fair amount of design was nailed down but it eventually proved to be too ambitious. Also, some team members left the company or moved to other projects leaving Arc Angel with a lack of resources. Eventually the game was cancelled and Chris was put on Quest as lead artist.
Some more info can be read in another article from the same site:
He told me Seavor was initially on Conker 2 but then moved onto a racing project which was cancelled. Supposedly he is now on something MMORPG. This was some really interesting stuff but I wanted to find out more about it so I asked Tony Wong as well. He hadn’t heard about the racer but confirmed that the Conker team has been disbanded. As for the MMORPG, he said he couldn’t comment on it since it was not official.
I remembered a post in the FatBabies forums about Nintendo cancelling a futuristic racer and asked Martin if this was the same game. He told me it was the Rare management — not Nintendo — that had cancelled it and that it probably was futuristic. He explained that Nintendo always leave people alone if they produce good work.
Sadly there are no preserved images or videos about Arc Angel. If you know someone that worked on this prototype, please let us know! We would love to save some screens in the archive.
