Marathon 2: Durandal

Marathon 2: Durandal is the second installment of the first big Bungie saga, developed by the same team as Halo and Destiny, which was released for Macs in 1995. This game picks up where the original left off, this time with an even more extensive campaign, as well as additional multiplayer modes.

Bungie released the code for Marathon 2 in 1999, just four years after the game's release. This led to the development of Aleph One, an open source engine designed to run the Marathon trilogy on modern computers with Mac, Windows, or Linux operating systems. This version of the game takes advantage of the same engine, which means you can play in panoramic, high resolution format. You can also customize other aspects of both the graphics and controls.

The campaign in Marathon 2: Durandal lasts longer than the first game of the saga, with more locations and new enemies. There's also a new weapon: the shotgun. Beyond that, you can carry two weapons simultaneously to double your firepower. Overall, this is a longer and more entertaining campaign that completes the story begun in the original. You'll also need to pay attention to the terminals you find if you want to learn more about what's going on around you.

Marathon 2: Durandal was a great FPS in 1995, and it still holds up, thanks in large part to the Aleph One engine's improvements. The best part, however, is that there are several multiplayer modes in addition to the story mode, so you can easily play with your friends.
