Hellomyname Keyes
From Halopedia, the Halo wiki
On the Truth and Reconciliation in Halo 1, you will need to save your sniper rifle till you save Keyes. Zoom in 10x and if you look closley at the name tag among Capt. Keyes you will see above it, says HELLOMYNAME then below it KEYES, unknown to why the IS is gone from the phrase.
