The Poke646 Website offers the release of Poke646: Vendetta, celebrating the fifth anniversary of the first installment in this Half-Life modification. For the moment this requires the Steam edition of Half-Life, but word is: "For the Steam non-lovers, we will post instructions on how to get P:V running under HL 1.1.1.0 within the next days. It's buggy, it's ugly and it's not supported... but it works."
