Allen Carr Mackey, best known in the Destiny community as ‘DrDrizzay101,’ died on Friday from carbon monoxide poisoning, according to one of his friends. Mackey was 33.

Mackey was well-known to other players—particularly on the Destiny NeoGAF community—as a kind, considerate, always-helpful Destiny addict with a seemingly endless amount of patience. He helped guide friends and strangers through flawless raids, the Trials of Osiris, and many of Destiny’s other challenges, from simple to excruciating. I played with him a couple of times and always appreciated his enthusiasm.

On NeoGAF today, other players are sharing thoughts and condolences. A small sampling:

Our best wishes go out to Mackey’s friends and family. He will be missed.
