As long as it is easier as MGS3 HD and less painfull as MGS2 HD, it took me almost 1week to defeat the last boss on extreme until I found I could stop his attacks and shooting the frogs on MGS3 has annoying too.
Luckily there's nothing like the Kerotans in MGS4. I'm guessing the trophies will be something like:
- The usual 'you completed Act
x'
- Maybe ones for beating bosses
- Find unusual Octocamo (like Hand)
- Collecting all guns
- Amass 9,999,999 Drebin Points (or something similar)
- A certain number of kills with certain guns/weapons
- A no kills, no alerts, no continues completion
- Find certain things in cutscenes using the Metal Gear Mk.II
- Hide in a bin
- Buy a gun on a Wednesday or Sunday during Act 5
- Get some emblems
- Get half of the emblems
- Get all emblems
- Download music and/or camo
I'd be surprised if they reactivate MGO for the re-release but I suppose they either have to exclude it or reactivate it. If they do I wouldn't be surprised, but I would be disappointed, if there were trophies relating to it.
