Stasis field glitch
From Halopedia, the Halo wiki
The Statis Field Glitch can be done as you play through Cortana and reach the part where you rescue Cortana. There is an interesting glitch. When you're done watching the cutscene, hit the pedistal where Cortana was; it should make the *sizzle* noise that happens when you hit energy shields, but there is no visible Statis Field.
