Been playing MGS2 on the HD collection lately...Still an amazing game, but I've blundered a bit on my Platinum approach.
You have to collect 218 different dog tags, which means you have to play the game 5 times through...Already played it twice through on Very easy and Easy, but realised that they're actually on seperate saves...
Apparently, to carry over dog tag progress, you have to press "load game" from the main menu, and the select the "new game" option...How backwards is that...I started a new game under the impression the tags collected just automaticaly carried over....Slightly pissed off I basically wasted my very easy run, since that the Easy mode tags are now on seperate save files, so I'll have to replay one of them, so I think I'll come back to that at a later date, just annoying that the way it's set up isn't really obvious to the player...
On a related note, you can't quit the game through pausing and selecting it from a menu...You have to pause the game, and then hold down all 4 shoulder buttons and start and select at the same time for 5 seconds LOL...You'd think they'd have changed all these dated ways of doing things for the "re-mastered" version.
