MSA is trash, or should I say Waifu Panty Attack? is a worsened version of the MSD focused on the sexualization of the characters, just horrible, lost the shine of the Metal Slug franchise, is no longer “Metal Slug”, that same shine that the MSD has, or at least had (damn collaboration event), MSD had everything to become an incredible game, but unfortunately SNK didn't realize it, probably because it was sold to a Chinese company, soon after, the game was abandoned and the MSA was launched...
And now in 2020 SNK was sold to an Arab company, is that a hope? hope so.
