During the final stages of Omega, the player takes on Panoptes. In every instance the boss shows up (including all instances preceding the final fight), the player can use the exotic grenade launcher Witherhoard to prematurely kill it. Its blight effect appears to be able to attack the eye, which seems to be hidden below the boss until it is scripted to be made vulnerable by Osiris. A direct hit with one grenade is enough to completely deplete the boss's health. Other weapons don't penetrate the boss's plot armour and can only hit the unprotected eye, which only shows at three scripted points in the final fight. If Panoptes dies, it does have a death animation. [b]Why this is an issue[/b] If Panoptes is killed in any instance prior to the final fight, the player may still continue. However, if Panoptes is killed during the final fight before Osiris helps the player hit its unprotected eye, then the boss won't be present at all when the player follows the scripted fight. The only course of action thereafter is dying to reset to a checkpoint. Scripted events continue as if the boss is still present, and the player will still receive degenerative damage if the field boss at each stage is killed as normal. The issue isn't game-breaking as it doesn't seem possible to be stuck resetting to a prematurely dead Panoptes. Still, it's kind of broken.
