Jack Bros.[a] is an action video game developed and published by Atlus for the Virtual Boy, released in late 1995 in Japan and North America.

It received generally positive reception for its gameplay, but was criticized for the lack of puzzle elements and under-utilization of the Virtual Boy's 3D effect.

[7] Jack Bros. was developed and published by Atlus for the Virtual Boy, and was released on September 29, 1995 in Japan,[8] and October 1995 in North America.

[9] According to Nintendo Power, Atlus did not reveal any details about the game's development,[10] although it is known that it initially was planned to be titled Devil Busters.

[3][17][19] In 2003, the staff at Tips & Tricks stated it to be the most uncommon North American Virtual Boy release, giving it a rarity rating of 6/10 based on a consultation with Digital Press.

[19] Nintendo Life's Dave Frear enjoyed the game, but wished it had included some puzzle elements rather than focusing entirely on combat; he did however find the strategic thinking involved in going back to earlier areas and figuring out how to save time to make up for this to some extent.

[3] GamesRadar's Mikel Reparaz called it "excellent [and] solidly designed" to the point where he would keep playing it despite the eye strain the Virtual Boy would give him.
