WingNuts 2: Raina's Revenge is a 2006 top-down multi-directional shooter for Mac OS X developed and published by Freeverse Software.

The player takes control of several historical and fictitious aircraft as they travel through time to stop Baron von Schtopwatch.

[2][3] The player controls a pilot in a series of airborne missions, hopping to different geographical locations and time periods in search of the villainous Baron von Schtopwatch and the mysterious Raina.

Once a player has destroyed all enemy fleet and ground weaponry, a boss character appears, whose defeat unlocks the next level.

[4] Macworld's Peter Cohen praised WingNuts 2's gameplay, graphics, soundtrack, and sense of humor, and called it "a fantastic sequel" to the original game.
