Man this game was so amazing. Coming from wolfenstien and doom, it was a technological marvel. I remember being wowed by the fact that it had liquids, and vacuum, and maps that spanned multiple levels vertically. The map had moving parts, like elevators and collapsible staircases and stuff which was amazing. And then the whole plot- psychotic AI, alien invasion, exploring abandoned spaceships, etc.

Then the sequels shipped with the map editor that let you put together whole scenarios yourself, it was crazy good. As a Mac user in the 90s, it was one of the only times my pc friends were game jelly- it was Mac only!

Then bungie made two other amazing Mac-only franchises, Oni and another one you might have heard of, Halo. In classic Microsoft fashion, they bought the studio and fucked everything up and changed Halo from an amazing team based, story driven co-op alien invasion epic into an increasingly generic fps franchise to sell Xboxes and merch.
