FRONT MISSION 2: Remake

Presently not unlocking. Towards the end of the game you will face a series of interlocking battles with your team split into three squads. The final squad faces off the coup rear guard in an airport setting that has four hangars with destructable doors you can destroy as you wind your way over to the objective. One of the doors has a plot oriented secondary goal hidden behind it but you can destroy the doors in any order before the mission ends so long as an enemy unit is still alive. It should be easy, straight forward achievement but it's sadly glitched right now.
