Defeated the queen last night all by myself! Died five or six times though but i did it by staying near the entrance as it gives you cover and cannot be destroyed. The weapon of choice was the frosty stick (I forget its name) it totally wasted the queen quite quickly? It was also doing one hit kills to the Seekers, which was strange? As its not like that outside the queens nest? Anyone else used the frosty stick to defeat the queen.
