Mass Effect 2 - Geth Colossus Boss Fight (Insanity)

Battle against the Geth Colossus on Insanity difficulty. The only hard thing about this is getting to the Colossus with your allies in tact, if you have med gels then it's easy enough. If you get to the sniper position I was in the Colossus goes down rather quickly but the only problem whilst you're here is if geth come up from your side, this is where you need your allies alive as they stop the geth from advancing onto your position.
