Ah, the beauty of rumors. Everyone was excited about Half Life 3 and some recent rumors made gamers believe that Valve would announced this highly anticipated title sometime in 2014. Well, that won’t happen and according to voice actor John Patrick Lowrie (voice of the sniper in TF2 who has also worked in HL2 and DOTA2), Valve is not currently working on Half Life 3 for various reasons.
As Lowrie revealed, Valve is not developing HL3 now for several reasons. Among those reasons is a mo-cap issue that Lowrie explained in another comment.
“Here is the biggest challenge with bringing out HL3: the big thing now with FPSs is motion capture, or mo-cap. One of the great things about HL2 is that all of the characters that you meet actually look at you when they talk to you no matter where you go or stand. With mo-cap you can’t do that, at least not yet. Once you film the actor doing something and capture that motion, that’s what the character is going to do. This works great in movies, but when you make something interactive it gets way less interactive with mo-cap. So that’s one of the things they’re working on.”
Naturally, conspiracy theorists will claim that Jowrie can be wrong. On the other hand, those closer to the project seem to agree with Gabe’s comment about ‘Valve not working/discussing/talking about HL3’ at the moment.
There is nothing really to add to this story, other than current tech seems to be the biggest obstacle of HL3’s development.
Lowrie did not reveal any other reasons for HL3’s absence… but then again… who needs them when the project has been put on hold?
