Entering the name "KOJIMA" into Jordan's data file will show Hideo Kojima's personal information.

The Metal Gear Mark II in Metal Gear Solid 4 appeared first in Snatcher. The Mark II is also inspired from the model that Snake fought in the first Metal Gear on MSX.

The initial versions of Snatcher on the MSX2 and PC-88 ended on Act 2. The developers originally planned to add Act 3 found in the later ports, but they had already went over the planned development time.

While Hideo Kojima was developing Snatcher, he wanted to coat the game's floppy discs in a chemical that, when heated in the computer, would give off the smell of blood. This was to "give the stench of a murder scene".
