GOG released this game as 1.07, not the 1.50 updated version.
1.50 changelog:
full hardware 3D sound (with EAX) with support for dolby surround 5.1
optimized rendering (5-20% faster)
support for occlusion culling
major improvements to skeletal animations (seen in updated tech-test level)
support for hardware vertex & pixel shaders (seen in updated tech-test level)
Parhelia triple-head support (support for three monitors)
detection of newer graphic cards (ATI Radeon 9700/pro, ATI Radeon 9500/pro, ATI Radeon 9000/pro, NV GeForceFX, Matorx Parhelia, SiS Xabre 600/400/200)
no more syncbads in multiplay
recoded demo rec/playback (no sync problems) and more...
I wish the version would have been listed on the website, what a rip.

It's because the Second Encounter BETA Patch 1.50 is an unsupported version without reverse multiplayer compatibility.
From Changelog:
1.50 is not net-game compatible with older versions. everyone need to upgrade - both servers and clients.
Save games and demos are NOT retained from older versions to 1.50
Since the patch isn't offically supported and the majority of servers online are still running the latest official release v1.07, GOG didn't short change anyone and released the proper latest version.

Does the patch work with the GoG-version? Thena maybe it should be added as extra or something...


EDIT: No, it doesn't. Now I would really like to see it being added as an optional update :(

I would also appreciate the GOG version being updated to 1.5. I don't particularly care about online compatibility, as I only play multiplayer on LAN, and with large number of enemies the sync errors (which are fixed in 1.5) are problematic.

It is pretty much necroposting... but I'd like to say that the patch DOES work. You just need to install it manually and use a nocd crack.

- Download the game[0]
- Download the patch[1]
- Download the no-cd patch[2]
- Install the game normally
- Open the patch .exe file with 7zip (other archivers might work too) and unpack it somewhere
- Copy the content in the SSSE installation directory
- Unpack the crack, copy the new .exe in the bin directory
- Execute the game once and leave
- Setup the resolution in the .ini file[3]
- Fire the game and enjoy!
