How to unlock the Area Secured achievement in Iron Man 2 - Definitive Guide
You can get this right after you finish escorting the S.H.I.E.L.D strike force ships. You will fight a big robot named 'Roxxon Armiger', then progress up the small hill and fight a few more air bots. You will come to a part where you need to destroy 6 turrets. (3 on the left and 3 on the right). Destroy them and you will be asked to enter a tunnel.
A short cutscene will play after you enter the tunnel. You will be asked to find the location of the command building. Ignore this for now and go crazy killing all the enemies (This is where 10 S.H.I.E.l.D units must survive). You must be quick or all the S.H.I.E.l.D units will die. Just keep locking onto the enemies with rockets and kill until there are no more red dots on the radar. (The Green dots are the S.H.I.E.l.D units).
After all are dead head to the yellow circle on the radar. It will now tell you to go disable the generators, shoot your way into the building and kill the 2 robots that are present and then shoot both generators. (One is upstairs and the other is down). then head back to the first yellow dot and access the building terminal. (Tap ) Now just continue playing the level until you reach the 'Roxxon Armiger' and the trophy will pop up.
The trophy will be given immediately after a large tank appears on the field, which must be destroyed.
