You can go invisible while being attacked, and enemies (except a Big Daddy) will stop attacking you (although they remain red on 'X-ray' vision for a short while after).While remaining invisible, you can melee attack an enemy face on as long as they're not attacking you.There are two upgrades for the Plasmid, one removes the EVE cost to use 'X-ray' vision and the other removes the EVE cost to use invisibility whilst standing still.
