Mammoth MK. II

Number two on the list on the most powerful units in Tiberian Sun.
It is a giant walking mech that has two railguns and long range/anti air missiles called Mammoth Tusks. It can totally wreak havoc on a Nod base. It can destroy a cyborg commando while taking down the base defenses at the same time. A very valuable asset to a GDI commander's base.

MK-801/MK'd

Mythical recreation drug. Though an actual research chemical, it's more than unlikely that it's on the streets.

Rumors of MK-801 use/abuse, a dis. anaethetic more powerful than PCP have been floating around for a while now. When I looked into MK-801, it was over $150 for 10mg, not nearly enough for any kind of high... and the precise dosages are undetermined.

If there was any recreational MK-801 use, it would be ALL OVER the dextromethorphan underground.

Still, someones best friends cousin's sister's worst enemy tried it, and ended up tripping balls for three weeks!
Yeah, Johnny MK'd out last week, he's at the state hospital now.

The Calling (Mk II)

Clear your tears and dry your eyes
We live in fear and drunken lies
Douse the flames of evil dawning
The cold blade falls on misty morning
And for their sins we live and die
The angel cowers in blackened skies
So take my hand and walk again
We'll take a walk through yellow rain
She's calling, just calling...
She's calling, just calling...
So now's the time we hear the calling
While lovers feast by mirrored pools
A million cries from shattered faces
We dance in tune to the pipes of gold
She's calling, just calling...
She's calling, just calling...
She's calling, just calling...
She's calling, just calling...
She's calling, just calling...
She's calling, just calling...
She's calling, just calling...
She's calling, just calling...
She's calling, just calling...
She's calling, just calling...
