Originally titled Gundam Ace (ガンダムエース,Gandamu Eesu?, or Gundam A), it was published quarterly from No.001 to 004 as an extra edition of
the Newtype.com (ニュータイプドットコム,Newtype.com?) magazine. From No.005 it dropped the Newtype.com branding and switched to bi-monthly publication. It became a monthly publication (recieving its current name) with No.010.
The producer is Shinichiro Inoue, who worked on Monthly Newtype and Monthly Shonen Ace at Kadokawa Shoten. The first chief editor was Hideaki Kobayashi. Starting with No.064, Tomoya Hirao became the second chief editor.
Most issues of Gundam Ace contain at least one 'free gift' item. These may be used to promote a current Gundam work or based on original manga appearing in the magazine. In the three months leading up to the premiere of Mobile Suit Gundam 00, the magazine gave away a 00 pencil board, sticker sheet and poster. A continuing series has been keychains depicting Mobile Suit Gundam characters as chickens, based on a popular manga of the same concept. Other items given away include CM collection CD-ROMs, exclusive alternate manga cover sleeves and cardboard calendar cubes.
