Ahahaha nice
I thought this was lame for about the first 10 seconds as I thought it was a loop of your one-liner ground snake joke or something. I kept watching though and different things started to happen. I got more and more into it. Using the Metal Gear Solid 2 music helped a lot for watching it too (damn, I love that music). Nice drawing of Snake at the end.
Also, I believe the Chainsaw man was from RE4 and the guy he killed was Leon Kennedy...anytime I hear a Chainsaw now...first thing I think of is that guy from RE4.
All in all this is a very (oh god I'm gonna say it) very Solid movie. A well deserved 9 for you!
