Probably just a source engine update.

That's definitely a clue in that Half-Life 3 case. Definitely. No question about it.

Mines 3.7GB?

It's a trap!

Omg, they gave us free Half Life 3! I love them :O Show some love to valve, imma give em pies

Portal 1 also updated

Content type patch(portal had it too)

It's happening.
=========

joke aside, update seems to be adding another lenguage.

Those are the files that got updated.

Looks like they added 3 (impossibru!) new languages to HL2, and updated most of Source stuff.

It must be HL4, because Gaben can't count to 3!

Finally Half-Cake4left Fortress 3: Global offensive!

CS:S just updated too, and now I can't play any servers that hasn't updated themselves, fantastic.

Half-Life 3 is only 700 mb o.o

700MB.

700 / 233.3 (Gabe's Weight) = 3

HL3 CONFIRMED.
