I recently picked up the Metal Gear Solid HD Collection for Playstation 3 (also available on Xbox 360) from our local video game one-stop-shop Hi Tech Gametraders. Lucky break for me, Hi Tech had, what seemed to me, the last copy in the entire city.
I'm having a killer time going through MGS2 again. It's nice to play now that I'm older and can comprehend things better. When I first played MGS2 I was only 12, it was a fun game at the time, but I had no idea what the hell was going on. Even now, I'm learning more stuff about the MGS story than I ever did during my Nth play through. But damn can I still speed run through this game.
This fun pack comes loaded with HD re-releases of Metal Gear Solid 2, Metal Gear Solid 3 and Metal Gear Solid: Peace Walker which was originally released on the Playstation Portable.
If you wanna get technical, the Metal Gear Solid 2 game is the Substance version, which includes the MGS2 game and hours (I'm talking like 50+ hours) of extras, which ranges from challenges to non-canon stories all of which are a challenge and a boat load of fun.
Metal Gear Solid 3 is the Subsistence version, which includes MGS3 with the updated camera handling and Metal Gear 1 and 2, albeit it does not include the original Metal Gear Online, Snake Vs. Monkey game mode or Secret Theater mode.
For $40 some dollars it basically pays for itself.
Never has any set of games have such rich storyline and consistent gameplay which remain true to its nature but improve as the series progresses.
As for Metal Gear Solid 1, you can obtain that through the PSN network, unfortunately for Xbox 360 owners, you will have to find other means to play it, or you can read the Wikipedia article on it or something.
Although if you own a Gamecube or Wii, run out and get MGS: The Twin Snakes. It's MGS1 that plays like MGS2 and from personal experience, it's a bloody good game. Frankly it was the only game that I played on Gamecube.
So if you were ever interested in the MGS series, now is the time.
And just get it from Hi Tech Gametraders. Support local.
