Famitsu reveals this week that G.Rev will be bringing Under Defeat to Xbox 360 and PlayStation 3. Titled Under Defeat HD, the game will be released in Spring 2012.
Under Defeat is a vertical scrolling shooter originally released to arcades on Sega's Naomi arcade board. The game was also brought to the Dreamcast in March 2006 as one of the system's last titles.
It's currently unclear if the HD version will be a download or package release, or it will have the DC version's bonus content. We should find out once official announcement is made later in the week.
