J.J. Squawkers for the arcade (Athena/1993) is a colorful and fast-paced arcade action-platformer. You play as one of two bird brothers, battling through levels to stop the villains who bombed your treehouse. Worth for its cartoonish charm, tight controls, and uniquely aggressive difficulty. It never received any home console ports.

X2, also known as X2: no Relief or Project X2, is a 1996 shoot'em up for the PlayStation by Team17 and Ocean Software (and by Capcom in Japan). It's the exclusive sequel to the 1992 Amiga hit Project-X. Allegedly, Capcom collaborated also in the re-design for Japanese audiences.
