Also, if people are having trouble killing the Gray. You do NOT need the grenade. Go far away from it, let it extend its lance and then move forward. This takes three hit (1 with glaive [Im not sure if i should bother saying this as if you've killed the razor queen and not a Gray you're doing something wrong])
To get razor queen do a small nest, wait till there's 2-3 gloopes left and dont swing your blade or kill and gloopes in any way. Soon the queen will just appear. Sidestep her lunges and slash her body. She takes five hits (2 With Razor Glaive) When she digs her blades into the ground get as far away from her as possible her Spikes and spike balls will only make you flinch if you are using the Red Suit (Cant remember name) But the tunnelers will kill destroy. If you dont have the suit you will be killed by any of her siege attacks (Siege is when she digs her claws into the ground.) I just completed the game. Highest score on 3 catergories today ^_^
