Forums - [kryt3n] Moonstone - A Hard Days Knight

Hey all! I'm looking for an old PC game me and my siblings played back in the mid 90's.

What I can remember, is that there were 4 knights - a red, green, blue, and yellow one. Each started in a map, which was divided into 4 seperate places:
A savannah, a forest, a rocky mountain, and a swamp. There you randomly had to fight with different enemies, switching the gameplay from the top-down map to a side-view arena. Some of I can remember:

On the savannah were tribesman(?) with spears, in other times warthogs.
In the forest you had hedgehogs(?) falling from the trees.
In the swamps there were huge muddy monsters.
That rocky place, I can't remember...

What I can remember, is that there was a huge dragon which randomly attacked one of the players, and you had to slay it.

I can't remember what the plot was. The graphics were more like a serious game, with gorey imagery.

If anyone remembers what this game might be, I'd be thankful!
