The first known screenshot of Halo. The Warthog, while recognizable, is still quite different from the final version. This original version of the Master Chief is completely different from what shipped in the game, and the scenery is also very different. Like many shots around this time, the spartan (no pun intended) but beautiful surroundings led some to speculate that Halo's entire territory might be traversable with vehicles, with terrain automatically generated by an algorithm, and designers adding detail to special areas.
