Half-Life 3 ble som kjent aldri laget, så vi vet ikke hvordan det gikk med Gordon Freeman og verden. Skal vi tro seriens tidligere forfatter Marc Laidlaw, ville ikke Half-Life 3 (eller Half-Life 2: Episode 3) ha tilbudt noen avslutning heller. Det var nemlig planer om enda flere spill.
Laidlaw sier at han ikke vet om Half-Life 3 noensinne skal slippes, men selv om utviklingen begynte er han ikke interessert i å gå tilbake til Valve:
"No idea. And I have no interest in going back. I had ideas for Episode 3. They were all supposed to take the series to a point where I could step away from it and leave it to the next generation. I had hoped for a reset between HL2 and HL3 that was as dramatic as the shift between HL1 and HL2. --- Unfortunately, I was not able to do that. But I never thought as far ahead as HL3, unless you were to say that HL3 and Episode 3 were the same thing."
Han fortsetter med å fortelle om den planlagte slutten:
"I will say that I expected every installment would end without resolution, forever and ever... --- My intention was that Ep3 would simply tie up the plot threads that were particular to HL2. But it would still end like HL1 and HL2, with Gordon in an indeterminate space, on hold, waiting for the next game to begin. So one cliffhanger after another."
Og når det er sagt, forsetter Half-Life 3 å være spillbransjens mest interessante spill som ikke er under utvikling.
