Here's the unofficial* Precursors v1.6 update by Wesp5.

*Use at your own risk.


This patch was previously known as the "Unofficial English Translation" patch, but now includes support for both versions (English and Russian).

Changelog:

v1.6 12.07.2012
----
Fixed mission-order issues for Doctor Amon and intelligence officer.
Continued improving translation, names and similar inconsistencies.

Fixed Misa not accepting fuel and Ramall's missions end and double.

v1.3 Notes:
It was renamed from Unofficial English Translation Patch to Unofficial Patch because it works on both Russian and English versions of the game. In fact it is planned that the next official patch for the English version from GFI will be based on it, so please report any critical issues, mission bugs or other suggestions. It was tested in space and on the first two planets (Goldin and Sunax), but the other four planets need still to be done…
