Today is Metal Gear Solid 2: Sons of Liberty from the Master Collection, Volume 1 on Steam. This is really just the HD edition from a decade ago though. But they did seem to enhance the visuals a bit, and like the other collection games, it comes with some background material like a Screenplay. This was probably my 20th time playing this game on yet another platform since the original.
Here messing around with soldiers. I like the markers over their heads.
Magazines come in handy.
I also like a lot of the in-game posters. There's some mods for these too. You should give Ghost Babel a try. It's non-canon, but still a great game.
More "interesting" posters.
There's an easter egg early in the Tanker if you find a specific poster of a woman in a locker and stare at it just right, then call Otacon.
Great game. So many little details.
