You probably never heard of them, and I could understand why, because many of their games are highly un-memorable, but something really interests me about many of their games. Here's some of the games they've made and a brief synopsis of them:
High Voltage:
First person shooting game with pretty impressive graphics for 1985. KLOV says that the game had speech, but I don't remember getting to any parts of the game that had speech back when I played it.
Time Soldiers:
Your comrades have been captured and have been forced to travel back in time by Gylend! Now you must save them! Overhead shooter game similar to Ikari Warriors. The music in this game is really weird, I don't even think the way it sounds in MAME is the way it sounds on the actual PCB/arcade cabinet.
Sky Soldiers:
Basic vertical scrolling shoot 'em up. The plot of the game according to the flyer is:"EXPERIENCE THE PAST......TO PREPARE FOR THE FUTURE". Wait, why do we need to go back in time to prepare for a future war? That makes no sense! We should just go over and kick the enemy army's ass. Anyway, not a bad game. The music sounds exactly the same as in Time Soldiers, and I also think that how the music in the game sounds on MAME is not how it sounds on the actual PCB/arcade cabinet.
Gang Wars:
A beat 'em up with the most GENERIC storyline you could ever think of. Some girl is kidnapped by some dude, and two other dudes go to rescue her. Generic story aside. Pretty interesting. And before each level, you can raise your characters stats such as defense and offense and speed.
Blue's Journey:
Cutesy platformer where you rescue a princess or something (Yay, another generic story!), and a pretty good game. One of the company's best IMO.
Ninja Combat:
This is a title of theirs that I saw ALOT back in the early 90's. To guys named Joe and Hayabusa go to beat the ninjas in the ninja tower, but the game doesn't tell you why. Probably one of their more well-known titles. It's gotten compared to "Gang Wars", but I can't really see the similarities other than that both games were directed by Tsutomu Maruyama, and a city backdrop in the game looks like the one from the first level of Gang Wars.
