If I had to build this character I would do this:
Race Half elf with skill versatility of Stealth and Athletics with +1 to Dex and Con
Background Soldier with the skills of Intimidation and Investigation
Stats
str 8 dex 16 con 14 int 12 wis 14 cha 12 (after race and feat bonuses, 27 point)
Class
Class breakdown of Rogue 4 (Scout) / Monk 2 with the feat Crossbow Expert
Rogue skills being sleight of hand, acrobatics, perception and deception and expertise in stealth and thieves’ tools
Equipment
Hand crossbow and light crossbow with a dagger and shortsword.
This build gives Solid Snake amazing amounts of skills, incredible speed and maneuverability, ninja stealth skills, and CQC levels of beat down.
