По словам David Hufford (Product Manager, Microsoft Xbox Group), выход Half-Life 2 на платформе Xbox, по всей видимости, не состоится. Вот небольшой отрывок из статьи опубликованной на Business Journal:
In addition, Hufford acknowledged that another anticipated combat game sequel, Half-Life 2, made by Seattle game developer Valve Software, won't be available for the Xbox as had been previously announced.
"As of now, Half-Life 2 is not going to be on the Xbox," he said.
"Valve is sending us mixed messages on that."
