Half-Life: Decay, the final, and most often forgotten expansion in the acclaimed Half-Life Anthology, as never seen before! Half-Life Decay: Solo Mission is a fan project that aims to rebuild every chapter from Decay from the ground up, give it a fresh coat of polish, and then retool it all to make for a seamless single-player experience, all without sacrificing any of the quality, gameplay, or presentation of the original expansion.

Planned Features:

Remade Decay campaign, retooled for single player

A newly implemented subtitle system, complete with English, French, Italian, German, Spanish, Chinese, Korean, and Russian localization

Full support for both the original, and HD pack models

Commentary mode, showcasing the development of Solo Mission

And perhaps even more...
