<p>Paul on the new quake content:</p><p><br></p><p>The two "new expansions" is both made by Machine games. Dimension of the Past was a downloadable expansion pack they made for Quake’s 20th celebration. You could download it from their website. Dimension of the Machine is brand new and made for this release. Both are excellent and well worth a play. </p><p><br></p><p>The best part of this release is the addition of the sound track, which was originally CD audio tracks on the CD disk. Previous releases of Quake on Steam and GOG did not include this. In a way, this is the most complete Quake version. </p>
