Took out the Super Mutants in the Revere Satellite array today without power armor by 'convincing' the NPCs in the farm nearby to join the battle to draw fire whilst I sniped the 'muties with the lazer rifle across the river. Fun times.
Both me and my colleague realised that mission is much easier if you go wide around the dishes and attack from the back or the side. If you head straight to it from the farm they shoot you through the trees when you can't even see them.
You not seen my mega sniper? One shots damn near everything.
