Rules of Nature

"Rules of Nature" is the boss theme and image song for Metal Gear RAY (Unmanned Gear) and Grad in Metal Gear Rising: Revengeance.

The lyrics describe a metaphor for survival of the stronger in the animal kingdom, but moving the logical sense to today's society. The comparative reflect Raiden as the weak prey (smaller physical size), and Metal Gear RAY as the strong predator or hunter (size, material of his body, military equipment and power), showing that the force is not always won and the ingenious can be victorious. In confrontation with GRAD is similar: GRAD is an armored Metal Gear, equiped with machineguns and shields, but Raiden can break it with his resonance-blade.

Lyrics
The time has come to an end!

Yeah! This is what nature planned!

Being tracked by a starving beast

Looking for it's daily feast

A predator on the verge of death

Close to it's last breath

Getting close to it's last breath!

RULES OF NATURE!!

And they run when the sun comes up!

With their lives on the line!

ALIVE!! For a while!

NO CHOICE!! Got to follow the laws of life!

ALIVE!! With their lives on the line!

NO CHOICE!! Out here only the strong survive!

What's done is done

Survive to see another day

Death and life, the hunter and the agile prey

No guarantee, which of them will succeed: the strong or weak?!

AAAAAAAAAAAAH!!

RULES OF NATURE!!

RULES OF NATURE!!
