Simply load up the campaign mission 'Loki' and proceed through the mission until you activate the console. You must be really careful and precise with your shooting, a general tip I tried to follow was start from your allies and aim at the targets closest to them first (making sure to not shoot any of the blue) and then finish off the remaining enemies, time is not your friend here so you must try and be quick and if you do not get everyone, revert to the last checkpoint. You can be unlucky with the final wave of enemies and hit a checkpoint before the blasts have occurred and this means you have to restart the mission if you do not kill everyone so beware of that (I had to restart 4/5 times).

Hope this helps.
