As if the leaked screenshots hadn't already confirmed it, it does indeed appear that the still-unannounced Xbox LIVE Arcade port of Sega's Sonic Adventure is headed our way.

Destructoid reader Damon sent along word that the XBLA version of the title was recently reviewed in the latest issue of the UK magazine, 360 Gamer. According to the review, the game is a "no frills" port of the main game featured in Sonic Adventure DX, the enhanced GameCube update of the original title.

The reviewer was mostly unimpressed by the port of the game that originally appeared on the Dreamcast back in 1998, saying it "really hasn't aged well."

"It's not all bad," writes reviewer Mark Podd, who gave the game a 5 out of 10, "but if your idea of a decent Sonic game is watching the Blue Spiky One charging across a 2D landscape, you'd be best advised to give this one a miss."

The review's details list a "to be confirmed" price and release for the XBLA title, which has yet to be announced by Sega at the time the magazine hit newsstands.

[Thanks, Damon!]
