"Our sources have told us not to expect one iconic weapon in HLA, however. Each of these sources mentioned that a virtual crowbar was tested at one point in the game's multi-year development but was eventually scrapped. To be clear: we don't have conclusive evidence that the crowbar won't eventually appear in the game in one way or another. (If Valve plans to upgrade the game with a physical crowbar purchase, my sources sure haven't heard of it.)" - From Ars Technica
No crowbar, huh. And I doubt they'll give us a wrench either.
Still excited to see what they do with this.
And also, in the same article it says that this game is between first HL and HL2, and from Alyx's perspective.
HL2+Episodes from Alyx's perspective would be shooting combine while a genocidal mute person stares at your ass.
