This is a standalone Patch/Update for those who had already downloaded the full mod when it was on v1.2. To get the Patch working just unpack the .ZIP and move the "Half-Life Evacuation Point" folder into your mod folder and overwrite the files.
v 1.2.1 changelog:
1) Hid that seam on the cliff on 77h
2) Supposedly fixed that elevator sequence on 22b (again)
3) Other minor fixes
That's it for now, stay tuned for future updates!
