This looks awesome.

New screenshots for it. Liquid physics look epic

If I'm right this is the new source engine that will also be in hl2 ep3.

 

[Yami]

Yeah, it's really obvious when you watch the trailers that there's a new engine. Liquid physics and lighting, mostly.

New trailer Make sure to watch it HD
You can see Valve really want to show off the engine; you get to see companion cubes and turrets being constructed from scratch ^_^ And the lighting enhancements are made much more obvious, too.

Also, wootness at a non-villain British voice actor ^_^ Well, presumably non-villain.

Couple more new trailers, both show off the new physics and much vaster level design.

hmm like both Wheatley voices but I preferred the one in the earlier trailer.

 

[Yami]

Yeah the earlier one is better. The second Wheatley voice is by some actor popular in the US, from The Office or something like that.

 

[Oreo]

They are the most disappointing water physics ever. Phun physics are better Still thats a step up from no water physics in 99percent of games.

I like the lighting engine however.
