I start fighting off some mechs with Garrus when the Blue Suns send in their heavy mech. Luckily, I reprogrammed that one so it would attack them (leaves the question why the hell it attacked me later on --perhaps I just turned off the friend recognition) and some infantry as well. I fight these off, and the tech armour actually proves to be a very, very useful tool. (Remember: I'm still learning about Sentinels :P) Anyways, Garrus notices that there's a breach on the back of the building, and sends me to close some shutters before the enemies, mainly Krogan and Vorcha, can reach the inside of the building. In this video, I manage two out of three, the third is yet to come.
