Valve Software is still working out exactly what it's going to do with Half-Life 2: Episode Three. "We don't know entirely what's happening in the next episode, but we're gonna figure it out!", a laughing David Speyrer, Episode Two project lead, has told PC Zone magazine. "There are always things we want to do that we can't because of the constraints of either the story or the arc we've laid out for the gameplay - or just time", he continued in a feature dissecting Valve's Orange Box, part one of which you can read on PC Zone's site here. "So we shelve them and carry on. Ideas fly around here quite a bit, so we have this huge laundry list of things to try for the next thing...", Speyrer concluded. Don't expect Episode III any time soon then by the looks of it.
