Title says it all. Rather slighted about this as this was a treasured game for me and a buddy. While we loved playing it on the same console as it was designed for, the idea of it coming to XBL was only extra awesome for the addition of achievements.
Highlighting the Achievements option in the main menu disappointingly brought up Local Game Only under it.
Luckily, it's not a super difficult game and I wound up making it to the 8th map in no time on my own. Just sucks b/c we practically completed the game last night but no achievements. Bummer
