The symbolism of the trailer as analyzed by a Youtube commenter:
Helicopter = Kojima Productions
Left behind soldier = Konami
Mother Base = Metal Gear franchise
Zombies = Fans
Survivor team = Pachinko machines
Give it a try, it's fun to watch it with that in mind.
I gotta say everything about this
so far looks really stupid. Even the title is a joke, "Metal Gear Survive", with a big "V", like it's part of MGS V, when it's not even called MGS..
