Defeating gray with turret
This is very simple all you have to do is first kill of the turret. Just throw 1-3 JB genades the turret dosen't shut down throw another one (be careful of imlumiati soldiers just turn mutant for them). Thats the turret down! Next refill health and mutagen and shoot one shot of the messon cannon to weaken it then shoot it with parasites (the shield is weak to parasite for some reason.) Be careful of iluminati soldiers remember. To finish it off (the sheild should be red before trying this). Get your BBG and finsh of the sield and gray!
