Gun Lord (Neo-Geo & Dreamcast)

NG: DEV Team has updated their Gun Lord teaser site with some new pictures. The game could almost pass as Turrican 4 if it tried. "Jump. Shoot. Explore.", says the slogan at the bottom of the page.
In the 1st shot, there's a bunch of gems and the main character is shooting a multi way shot similar to Turrican. To the top right, another picture shows a flame shot that could be the "Surround" weapon. The BGM played on the page reminds me a little of Chris Hulsbeck's stuff.
Day one, damnit.
