I. Description

"Half-Life: Opposing Force Coop" allows you to experience the epic Opposing Force story and environment with your friends, or with players around the world. This following guide explains how to setup a working server.

II. Requirements

Half-Life and Half-Life: Opposing Force on either WON osr Steam is required to play. You must also either have an LAN or internet connection.

III. How to install

Note: It's recommended to make backups of any file you already got with same name if you need to before installing! (Backups of skill.cfg, skillopfor.cfg, listenserver.cfg, and server.cfg).

To install Opposing Force Coop, begin with downloading the newest version (v2.0) at the "Downloads" page if you haven't already. When the downloading is complete, unzip and run "ofcoop2.0.exe". You should see an install window popup. Click "Next" twice, and locate your WON or Steam Opposing Force folder. After you located it, click "Next" and "Start". Opposing Force Coop will now install. When it's done, click "Next" and "Exit" to finish the installer. Opposing Force Coop is now installed on your computer.

IV. Create/Join a server

Create a server

Step 1: Change settings

Starting a server is very simple. However, you need to change some settings first if you're gonna run a LAN server and/or you wanna change the servername and/or you wanna change the difficulty. Otherwise, just jump over this step.

First, find "listenserver.cfg" at your gearbox folder (C:\Program Files\Steam\steamapps\youraccountname\opposing force..), and open it with notepad. Now, if you scroll down, you should see text like this:

If you want to run a LAN server, change "sv_lan 0" to "sv_lan 1".

If you want to change servername, change +hostname "Opposing Force Coop v2.0 Server" to eg. +hostname "My server!"

If you wanna change the difficulty (1 is easy, 2 is medium and 3 is hard, default is 2), change "skill 2" to 1 or 3.

Step 2: Starting the server

Go to "Start -> All Programs -> [HLCoop] -> Opposing Force Coop" and choose chapter, then choose which map. After the server started, you'll need to type "restart" in console to make all monsters spawn.

NOTE: If you change map with the console, you'll have to fix the map levelchange by changing the mapcyclefile too. If you for eg. write "changelevel of3a6", you will also need to write "mapcyclefile of3a6".

Join a server

Start the game and go to the game menu, and click "Find servers". Now you can simply look for servers with the gametype "HL Coopplay".

An alternative option is to write "connect [ip here]" in console.
