Snake in Brawl was strange. Mainly because they were using a Big Boss face model on a Solid Snake outfit.
Naked Snake face and bandana, with MGS2 Solid Snake’s sneaking suit, with the codec portrait being completely new while all the other characters still use their MGS1 portraits. David Hayter using MGS4’s gruff.
His attacks ranging from every main entry in the series at the time, including a mortar based attack from yet unreleased MGS4. Even a mine digging move from MG1 and MG2.
Just a clusterfuck of references.
Don’t forget that a Gekko could bust through the Shadow Moses stage background despite MGS4 not being out yet.
