Bronze/Condor/Reapers (or geth): husband put the controller in my hand and told me to have a go with the Juggernaut. 'He's a big robot, no-one can kill you.' I had absolutely no clue what to do, what buttons to press, but off I went mashing buttons like I was playing SoulCalibur... 
I remember the map, as I had trouble seeing the enemies strolling down the slope (have some eyesight problems in one eye)
I naturally got hurt as cannibals went nuts on my ar$e, paniced and pushed the controller back to Arkhne.
But it did make me curious enough that I wanted to try it again... some weeks later after recovering from the shock.
