NoShitShurlock claims they have been corresponding with Quake Command founder and Half-Life level designer, John Guthrie, who reportedly confirmed details on Half-Life 3.
Guthrie is reported ot have said: "I can't confirm all too much since the development is still in early stages, but for now I can confirm that we are going to release on both current and next generation consoles and we will also release the game on our own platform exclusively for PC and Mac… We hope to have the first trailer ready for E3 2014, which we (after several times not attending) will finally come back to."
The report also goes on to state that Guthrie revealed that Half-Life 3 will only have a single-player campaign, with no co-op or multiplayer. It is said the game will also feature the main characters from Half-Life 2 with a story that picks up from where the last one left off. The game is said to be due out in late 2014.
