Let's make this birthday one to remember.

70 years old (Born on May 01, 1955)

Happy Birthday, Marty O'Donnell! May your day be filled with more epic moments than a Halo Warthog jump gone hilariously wrong. Your legendary compositions have given gamers goosebumps and made us hum Gregorian chants in the shower—much to our family's confusion.

From "Myth" battles that felt grander thanks to you, through Oni's futuristic beats, all the way up into Master Chief’s iconic adventures—you've scored countless memories alongside Michael Salvatori. Here's hoping this birthday is as timelessly awesome as your music; may it echo triumphantly like an overpowered plasma grenade toss!

Cheers for another year of unforgettable melodies ahead!
