half assed port more or less, just like the OG port of mgs2 there's no QOL enhancements for PC users and it's just a straight rip of the HD collection games. the best remaster wouldve been just getting the OG source code and compiling it again instead of using Unity and doing some internal reverse engineering for some reason. atleast MGS1 and MG 1 and 2 had some effort done into it
