Matt Soell throws in another teaser about Halo's plot close to the end of the game in this week's Halo update:
"- One thing I've noticed in recent weeks is that Eric tends to work on
some of the coolest stuff in the game - and naturally it's all towards
the end of the game and involves plot points that I can't even allude to.
But I can bring up small individual elements and let you guys wonder
about what they mean. What's green and gooey and eats through the ground?"
This might be a Marathon reference... then again it might not.
Cheers
