Update: TF2 Update Update
Things are afoot in TeamFortress2Land, things of tease and mystery. Firstly there's a new item: the golden wrench - a Midas weapon for the turning of people into gold - which internet boffins think might just be a clue as to the nature of the next update. But then there's this TF2 comic, which tells a little tale of an engineer's life, and unravels more of what seems to be an extra-complex history-explicating backstory for our favoured cartoonish shooter. All this seems ponderful enough... but wait! There are hidden links within the comic. On page four this, and then, within the source code of that page, a link to the obscured signature, here, and a portrait of the family, here. IT IS SOME KIND OF CLUE-BASED PUZZLE EVENT!
