Metal Gear Tale
"War Has changed..."
―A famous Quote
Metal Gear Tale is an Alternate Universe (AU) Created by THE WAR KID on the 28rd of April, 2016. The AU Mainly consists of crossing over MGS with UNDERTALE.

Main Story

Long ago, two races ruled the Earth, Humans & Monsters.

One day, war broke out between the two.

After a long battle, humans won.

They sealed them underground with a Barrier.

And they say those few who venture to the field, never return.

Metal Gear Tale is an AU that crosses UNDERTALE with METAL GEAR SOLID.

The AU takes place in the time slot between the birth of Solid and Liquid Snake, and the time of Diamond Dogs being active. The Diamond Dogs are splitting, some deciding to assist Solid or Liquid, while others remaining loyal to Big Boss. Liquid, Solid, and the Diamond Dogs had been trapped Underground in the confusion of the barrier being sealed.
