Let's Play Serious Sam HD - Part 8 - Memphis - Suburbs

With nothing to say about this level, let's explain why Mental feels the need to wipe out every life form in the universe. In the earliest eons of the universe, it was ruled by an ancient race of alien gods known as the Hum-Tah, or Infinite Ones. Of the Hum-Tah, there were three kinds: The Ones that are lost, the Ones that create, and the Ones that destroy. The Lost Ones traveled to infinity within the universe and were never seen again, the Creator ones were given limitations on their powers and eventually became extinct, the Destroyer Ones wiped out intelligent races to extinction for their own sick amusement and so they were banished. Only one Hum-Tah remained, Mental himself. He was slowly driven insane by loneliness and developed deep hatred and jealousy towards the younger races as they were able to escape the terrible fate that befell his Hum-Tah brethren.
