Embraceware Software has introduced Shuttle Scuttle 1.0, a retro-style shooter game for Mac OS X (10.6 and higher). It’s available for US$1.99 in the Mac App Store.

Here’s how the game is described: “Neptune station reports of unidentified spacecraft approaching. A hostile force is making its way through the sol system towards earth. Armed shuttles for asteroid destruction are the only defense crafts available.

“Seek out and intercept this hostile force before Earth becomes a target. Shuttle Scuttle features 14 tracks of original music with 32 levels with eight epic boss battles.”
