Meet perhaps the most interesting game on the NGPC (with some caveats of course). This game evolved from an old arcade shooter from SNK itself "Beast Busters". How do you say: here is an RPG, and there is a shooter. But you look at the creatures, they are the same here and there.
Anyway. And now for the plot: there was a group of people who called themselves Beast Busters (specialists in phenomenal and paranormal things). So, they say, among these people there is a book "The Contract of Darkness", which contains information about a super-weapon that helps to cope with enemies. But only one of this group dared to go looking for this weapon. It is you.
The game is quite difficult, you won't pass in one sitting. There are like 5 stages in total, but it is noteworthy that each stage looks different during the day and in the evening! The graphics are very high for this console, I would say super!
A little about weapons: you yourself try and experiment with them, creating new ones (shotgun, machine gun, tentacle, blade, etc.). No wonder the name of the game is "Dark Weapon".
