The first ever released images of Zelda 64(as it was called).

The game at this stage is running on a slightly(if at all) modified Mario 64 game engine which explains the extremely basic graphics. The movie clip these are from was shown at Spaceworld in 1995.

Link battling with some sort of knight in armor. The graphics at this stage are a complete joke, but they were never going to be left like this so it doesn't matter.
Link's actually constructed to look like Link from the original LoZ, who was quite short and cartoonish looking. But the metallic body of the knight is cool, why didn't we see something like that in the final game?
