Metal Gear Solid 4 GC 2007 Trailer - GameBrink
The first half is the same as the
E307 trailer, 2nd half is different.
The hovering puppetteer is '
Screaming Mantis'
The flyer is '
Raging Raven'
The dog-like one is '
Crying Wolf'
The betentacled one is '
Laughing Octopus'
They certainly fit the bill of strange MGS bosses. Apparently they were (still are?) all Human--women at that--, now fused with elements of Metal Gear.
I thought that 'Screaming Mantis' was 'Psycho Mantis 2.0', but it's a woman. Perhaps they're related regardless. Snake even says, "It can't be...", as if remembering Psycho.
I wonder if Raiden shares some of this technology with his suit...
