Well, I'm not familiar with Metal Gear so I don't know what capabilities are dealbreakers if they're missed.
If you're going to stick with character generation rules by the book, you're likely going to have to both pick Resources A as well as some sort of essence saving quality (Biocompatability: Cyberware from Chrome Flesh would probably be ideal), or spending extra on at least one limb so it doesn't cost the full 1.0 points. 6 "limbs" (2 arms, 2 legs, torso, skull) costs 6.0 essence otherwise, which is invalid. You must retain at least 0.01 essence or you're dead.
That gets past the first threshold: literally surviving the essence hit.
The next problem is less severe: being able to trick out all those limbs. Even at resources A, you simply can't afford to. Particularly so if you took one or more limbs at alpha grade to save on essence. But again depending on what you're trying to accomplish, you can put off upgrading and buying add-ons for your many cyberlimbs to post-chargen as you gain more money for doing jobs. Ever read Alita? Or see the movie? You can START play with what's basically a full body replacement, but you can't START play with a Martian Berzerker body
You'll have to start with something far less capable and work your way up.
