Getting close to the strange metal egg, you see that it isn't so much of an egg at all, unless its purpose was to perhaps hatch some kind of humanoid, which, judging from some of the features on the exterior of this egg's shell, isn't entirely so likely. There are circular things, and rectangular things of various kinds jutting out from the surface of this egg, as well as some grooves along its surface that just look way too straight and angular to be anything truly organic in nature.
Without much difficulty, you manage to find a seam that has been partially opened, but only for just a crack about an inch or two wide.
