World War Z studio wanted to remake Half-Life 2
Saber Interactive, the studio behind WWZ, said in a recent interview with GameWatcher that they proposed to remake HL2 but Valve denied the offer.
"After we did Halo Anniversary and Halo 2 Anniversary, as part of the Master Chief Collection, I reached out to Gabe Newell personally, because I knew him from a past life, and I said I want to remake Half-Life 2. That's all I want to do. I won't charge you anything for it. I'll do it for rev-share and doesn't even need to be a big rev-share. I just really want to do because I love that game so much."
It seems Valve has other plans for HL2: "Sorry, if we're going to do it, we're going to do it internally." It is a bit strange, to say the least, as Valve have allowed another studio to remake HL1.
