Great start! The idea of Umbrella having a working model of Metal Gear specifically designed to deliver the T-Virus scares the hell out of me.

This is a crossover i honestly never thought of and it's probably one of the most interesting ones i've seen to date.

I can't wait to see what will await snake in the facility. I assume there will be a T-Virus spill of some kind, or some B.O.W.s will escape and wreak havoc. Snake versus a Tyrant, or the Nemesis, gotta see that!

Keep going, i need to see where you're going with this.
