Half-Life 2: Episode 3 prototype in Unreal Engine 4

Valve will probably never released Half-Life 2: Episode 3, but it won't stop people from working on their own fan projects, including YouTuber 'Trebla Freeman'.

A new prototype version of Half-Life 2: Episode 3 has been shown, created in Unreal Engine 4 with a working gravity gun and all. We don't know if the HL2: Episode 3 prototype will be made into something real, but it gives us a glimpse into something awesome.

Please, Valve... please finish Gordon Freeman's story.
