Half-Life 2: Episode 3 would've included an ice gun with 'kind of like a Silver Surfer mode,' and Valve just released footage
Half-Life 2's third DLC episode was never finished because Gabe Newell and company didn't just want to finish the Half-Life 2 story arc, but to do something big and innovative with the game design, and as Newell put it in a new documentary, he was «stumped.»
But also in that documentary, released for Half-Life 2's 20th anniversary, there's footage of some pretty cool-looking Episode 3 stuff, including an ice gun that could be used to build transparent barriers, but also in «kind of like a Silver Surfer mode» that lets you run across ice ramps as you build them.

That wasn't enough for them, Newell said in the documentary.
«You can't get lazy and say, 'Oh, we're moving the story forward,'» he said. «That's copping out of your obligation to gamers. Yes, of course they love the story. They love many, many aspects of it. But saying that your reason to do it is because people want to know what happens next, you know—we could've shipped it, it wouldn't have been that hard. The failure, my personal failure was being stumped. I couldn't figure out why doing Episode 3 was pushing anything forward.»
Not everyone from Valve is in agreement, though: «We could've definitely gone back and spent two years to make Episode 3,» said
