Three by Scarab:
Survival Arts (1993)
Battle Monsters (Saturn, 1995)
(Hm I thought I posted about this before somewhere, maybe I forgot to type out the title or maybe I just decided it was too awful.)
Killing Zone (PS1, 1996)
Scarab (later Feelplus) also made Macross: Do You Remember Love and the Dreamcast port of Fighting Vipers 2 ( Feelplus - Wikipedia ).
