Japanese website: Twinbee. Originally released to arcades in 1985 by Konami, it was ported to Nintendo's Family Computer a year later. It's a two-player shooter or “shoot-’em-up”, similar in nature to Xevious.
So far, the 3D Classics series has given mild makeovers to Excitebike and Xevious. Urban Champion will hit the 3DS eShop next week in Japan, but the other two titles planned are currently unknown.
There seems to be a noticeable pattern regarding what titles become 3D on Nintendo’s service. None of them are hard-hitters such as Super Mario Bros., but instead more obscure or less critically acclaimed ones. With the exception of beat-'em-up Urban Champion, it seems that gameplay in these titles could genuinely be improved by the extra depth offered. We did not find Xevious to be particularly impressive, but perhaps Twinbee will fare better?
