Natural Selection v3.3

An updated build of the game Natural Selection for Windows and Linux focused on quality of life improvements and bug fixes.

Downloads

The Natural Selection Launcher (Windows) can install, update, or repair the game.

Manual installation (Windows / Linux)

As the game is a Half-Life mod, Steam and Half-Life installations are required to play the game.

A fresh install of NS comes with updated config files containing everything you need to get playing on the standard settings most players prefer. Customization options are also built in like the Nine Legends competitve UI option as well as team and weapon specific config files that can be edited.

Game not working? Troubleshooting tips.

If the game doesn't load, check the following:

1. Make sure you have verified Half-Life's integrity. Click here for detailed instructions.
2. Make sure you have a clean install. Go to the half-life directory (eg. c:\Program Files\Steam\steamapps\common\Half-Life) and remove or rename the ns folder.
3. Check if Half-Life works for you.
4. Make sure you don't have any additional command line options for NS.
5. For more help, ask on #help in our discord

For Linux:

• Remove or rename the libstdc++so.6 provided by steam or steamcmd so the linux distro's can be used instead. The one steam provides is outdated.
• 32 bit C libraries might need to be installed. Try apt-get install libc6-i386 if on debian or ubuntu.

Changes

Updates include:

• Natural Selection Launcher for installing and updating the game

• Widescreen support (now expands FOV up to 16:9 aspect instead of cutting it off)

• AI upscaled model textures can be turned on with the "Use High Definition models" video option

• Many FPS dependencies fixed, including jetpack acceleration, so the game can now be fairly played at 200+ FPS

• Quake style queued jumping to make bunnyhopping more accessible (server adjustable via sv_jumpmode)

• Shotgun and grenade launcher have been reworked to fix reload bugs

• Weapon reloads are now predicted on the client

• New minimal HUD and the Nine Legends HUD can be selected through advanced options or hud_style and hud_mapstyle

• New crosshair system that can be adjusted through the advanced options and cl_cross commands (Thanks OpenAG)

• Ambient sounds can be changed in advanced options or via cl_ambientsound

• Marine HUD now tracks research progress

• Raw input and sensitivity scaling options now available

• Numerous bug fixes

Compiling

For Windows, compilation should be working if you have VS2019 installed.

For Linux:

First you need some libraries. On Ubuntu it is:

apt-get install build-essential git gdb gcc-multilib g++-multilib libc6-i386 mesa-common-dev

Then you will need to get the files:

git clone https://github.com/fmoraw/NS.git

Then cd to the linux directory:

cd NS/main/source/linux

Then build

make

or make ns to build the server binary and make cl_dll for the client binary. make clean to clean.

If you get the this error when running the app: Fatal Error - could not load library (client.so), With a high chance it is because of some UNDEFINED SYMBOLS in the shared library. But you can check this with this command:

ldd -r -d client.so

Make sure you have vgui.so copied to the cl_dll folder too on Linux.

Debugging

Windows debug builds are currently broken.

If you want to debug:

LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH" gdb ./hl_linux r -game ns -dev -steam

Due to the new engine and the nature of Linux I had to make a lot of changes! You can find them with grep -Ril @Linux.

For MacOS & lldb:

DYLD_LIBRARY_PATH=".:$DYLD_LIBRARY_PATH" /Applications/Xcode.app/Contents/Developer/usr/bin/lldb -- ./hl_osx r -game ns -dev -steam -windowed

Have to use XCode's lldb to get around https://stackoverflow.com/a/33589760 (Lack of environment variables). -windowed as windowed mode makes it easier to deal with crashes on MacOS.

Hosting a server

Since servers are really rare at this point in time here is a tutorial how to set up an Natural Selection server with hlds.

1. Follow these steps: https://developer.valvesoftware.com/wiki/SteamCMD
2. Copy the Natural Selection directory to steamcmd/servers/
3. Run the game :

./hlds_run -game ns -autoupdate +map ns_eclipse + sv_secure 1 + port 27015 + ip 127.0.0.1 +hostname "Natural Selection" +maxplayers 32

If you are behind a NAT(Router) make sure to open at least those ports:

• 27015 UDP (game transmission, pings)
• 26900 UDP (VAC service) -- automatically increments if used in case of additional server processes

Under no circumstances expose your host to the internet!!! For more information follow this link.

In order to check if you server is connected to the steam servers copy the following url in your browser and replace <your IP address> with your external ip: http://api.steampowered.com/ISteamApps/GetServersAtAddress/v0001?addr=<your IP address>&format=json

There is an updated version of metamod called metamodp. Since players are also pretty rare you might want to install rcbot and therefore you have to download those files:

• rcbot without dlls
• rcbot linux dlls

Usefull links

• Usefull collection of ns files server addons, maps and everything

• Great collection of ns guides/tutorials

• rcbot downloads

• dillinger.io markdown editor
