We have added some great things that would basically make you look at the limits of the first unreal engine in a way more wide and open perspective.
Here's what is has been made, or is in development:
-Media Codecs
-Video
-GIF (Yes, even animated ones), JPEG, and other formats
-A brand, spanking new conversation system written from scratch with more features than the old one.
-Feature to add cutscenes to levels at any time.
-New menu interaction.
-Stereophonic sound, meaning you can import stereo tracks with Left and Right channels like MP3, WAV, WMA, etc. and get great quality.
-Geometry Interaction. You can walk up to a wall, or some certain form of level geometry and click a button printed across it like a touch screen device.
-The ability to overhear conversations. See if evesdropping can get you some info that you might need.
And that's just the beginning... Why spoil anything else? ;)
