Metal Gear Survive PS4 Iron Wall (In Six Minutes)

in order to get this trophy your base mustn&receive any damage. there are three ways to get this trophy the first way ( to fight the lord of dust final battle no damage from wonders or any creatures), the second way (your defense unit must be strong level S+ or maybe A+ to leave it to your crew of the dig plan 2), the third way ( finish the first wave of the dig plan 2 by yourself the same as the video just make sure you didn&receive any damage of your base so you can get this trophy). I recommend the third way because it only take 6 minutes and only two ways that enemy appear. I hope this video is very helpful
