Whats new there? Just a new look of the browser and matinee in the editor and 'daylight' with soft dynamic shadows are supposed to be a special feature. Keep it, Epic.
But the new maps are told to be modified also in their structure - in necropolis there are new, larger flag buldings, new incineration rooms, new gates, ...
The link gun has got face lifted and comes with a new primary fire animation.
Someone who is able to do so should make these maps ready to play on custom servers to try them, thx. Bastardbrain maybe, you know how to do maps and stuff, right?
