Doesn't work – Marathon 2: Durandal Review

I'm on a iPhone 6 Plus with IOS 8.1.2 and all 3 of the Marathon games are not working. I haven't played the series before so I was hoping this port would work. I'll update my software today, but since the last update for the game was 2 years ago I doubt it will do much.
