Jets 'n' Guns is a 2D side-scrolling arcade-like shooting game. It was originally released for Windows back in 2004 and then for Mac OS X in 2006. More information about the game-play can be found on the game's web-site. This game was developed by a game studio known as RakeInGrass.
On the LGP product page the release date is said to be December 1, 2008. That's less than two months away and it hasn't even entered beta. Quite frankly with X3: Reunion running more than a year behind and all of these other titles being ported to Linux by a few LGP developers, it will be surprising if this release schedule is met. More than likely it will turn into an H1'09 release. We'd suspect this game will also include LGP's game copy protection scheme. The price set for this game is £15.00, or about $25 USD.
