Atari has told us to expect Spark Unlimited shooter Legendary in September.
This is based around the idea of Pandora's Box being opened in the modern day cities of New York and London, and you using guns to stop beasties eating people and baddies claiming the box for themselves.
Spark Unlimited is the same developer responsible for Turning Point: Fall of Liberty, which also had a fetching premise of an alternate reality where Hitler and his troops broke Europe and then moved on to the US. But Turning Point was rubbish. Still, lessons learned and all that.
Atari also pencilled in a Q4 2008 release next to the PS3 version of Alone in the Dark. A way away, then.
