This game is gold i tell ya
Events were a blast and everything is balanced you'll be bashing your phone to survive one event stage
I still remember satisfaction of getting your first super weapon
Sad thing is MSD is no longer updated
I recommend Metal Slug Attack the successor to MSD but Uber unbalanced. Almost 70% of the units're outdated, outgunned to the point you'll ignore them. But this series still have sticking power. Great pixel art and animation with lots of fan service. I mean they goes too far with fan service. Female units outnumber male units. Id be lying if i say i don't like it
