https://mixer.com/Halo?vod=65957556 Pretty neat. They went completely "off-script" so to speak, and showed parts of the level in that build that had never been seen in public before. It was very surprising to me (and to them!) how well-made the build was because it was notorious for being unstable and prone to crashes. They also showed off another build of the game that looked close to the Alpha but unfortunately ske7ch appears to have zero patience for low framerates and buggy levels, as he pretty much backed out of each level instantly as soon as he saw there was little to do. Hoping these builds get released one day!
Man I still get chills watching that E3 demo. Such an iconic moment. I remember watching it as a kid and being so excited when that 2nd SMG started firing. Great stuff.
I'd imagine they're rather protective of those builds. Chances are we will never see them in person. Bit sad they had very little more to show in single player. Had hoped for years it was more fleshed out and they only showed what was polished enough to show off
