This game was first released on Super Nintendo Entertainment System (SNES) and then I have played it for the first time on the Playstation.
I killed the first boss in this game Neon Tiger.It's easiest boss for me.
On the "armor" in this game there will be two levels.When the fully armored (Legs, arms, head, body).
You can keep the two level armor have only one piece of armor.But it was a way to keep the two level armor all.It's called the golden armor
The conditions and how to keep the armor.Someone are already doing it on youtube.
