Rare Metal Gear Soundtracks?

There are a few rare Metal Gear games I never got my hands on. Since I’ve never played them myself, I’m not sure if they even have new soundtracks in them or not. Maybe you guys know more about them, so I thought I’d just give it a try 🙂

– Metal Gear Solid 3D Snake Eater [3DS] – Probably the exact same soundtrack as the PS2 game, but I’m not entirely sure about it
– Metal Gear Arcade [Arcade] – Arcade version of the MGS4 Metal Gear Online game. I’m also not sure if it has new/different music or not, but I guess it would be pretty much impossible to get it anyways
– Metal Gear Solid Social Ops [Mobile] – I don’t know much about this game, just that it exists/existed. Did it have original music or did it use music from other Metal Gear games?
– Metal Gear AC!D Mobile 3D [Mobile] – Probably just a mobile port of the AC!D game from the PSP, but since MGS Mobile got a gamerip, this one might have different music too?
– Metal Gear AC!D 2 Mobile [Mobile] – Same as above 🙂

I couldn’t find any information about their soundtracks online, so I’m wondering if you know about these games and if they use new soundtracks or not. Would be great if we could get a rip from one or another game, IF they have different music 🙂
