Iron Man

To unlock this achievement you must destroy all 3 conveys before 2 minutes are up in the mission entitled "Stark Weapons" which is the 3rd mission. This achievement can be unlocked during any difficulty but I highly recommend this on Easy.

This achievement is pretty much a given as long as you're quick to act. Two minutes is plenty of time to take out the conveys however don't take your time. Just make sure when you are prompted to destroy the conveys make sure you fly (using boosters) to that location on your radar. Typically destroying one will destroy the whole convey.

Below is my guide on how to beat this level (it was written for the hardest difficulty but still works just fine for easy mode):

============================
Mission 3: Stark Weapons
============================

Recommended Power Distribution: Life Support (up on the d-pad) the whole level.

This level starts out with the objective to take out 7 warehouses filled with weapons (each warehouse is marked as a orange dot on your radar). Approach these warehouses with caution since you can die pretty quickly if you rush in. Best way to take out all the enemies is to hover, take your time, keep your distance, and take cover (land behind something) to heal when needed. I recommend taking out most, if not all, enemies in each area.

The next objective is to take out several conveys, just fly to their location and shoot them with missiles. This is super easy if you took out most of the warehouse enemies early on. At this point you should have lost none or just one of your reboots.

The boss fight is with this super tank (I don't know what else to call it!). It has more weapons then space (I think they built a bigger tank just to house more weapons!). If you have 3 or 4 reboots you will have no problems. There is two ways to fight this massive super tank...

1. If your like me and have all four of your reboots, trail behind it and blast the heck out of it (hold RT and press Y every time your missiles are ready). You will die a few times but you will have enough reboots to waste him.

2. If you don't have all your reboots or you want to make sure you win. Trail behind the super tank and take a few shots, hide and recover your health... repeat. At one point the tank will stop moving, move to the top of the valley and shoot him from the top of the valley, land on the ground (on the top of the valley) to heal when needed.
