This Wednesday will see the release of Tozai Games' R-Type Dimensions through the Xbox 360's online Xbox Live Arcade platform, publisher Microsoft has announced.

Priced at 1200 Microsoft Points ($15), Dimensions contains Irem's classic arcade shooters R-Type I and R-Type II, complete with original and redone 3D graphics.

The title will also feature online cooperative multiplayer for both games, and a new "Infinite" mode said to assure "the completion of your game regardless of skill level."

As part of a press release celebrating Xbox Live Arcade's record-breaking year, Microsoft today listed the following downloadable Xbox 360 games as examples of Xbox Live Arcade releases that will help "ring in the new year:"

• Lode Runner / Tozai Games
• The Dishwasher: Dead Samurai / James Silva
• South Park / doublesix games
• Puzzle Quest: Galactrix / Infinite Interactive
• R-Type Dimensions / Tozai Games

No specific price points or release dates were provided.

In all, gamers have earned nearly 100 million Achievements from Xbox Live Arcade games, a feat that, according to Microsoft, amounts to 1.25 billion gamerpoints. Oh, and 110 million free trials have been downloaded since the service launched in 2005.

"Xbox Live Arcade has really become the top destination for premium downloadable games," said Microsoft director of digitally distributed games Scott Austin. "And we've got a long list of games coming out in 2009 that we think will be just as incredible as what we already have on the service."
