Even though I have Ep2 on my computer, when my friends play it they see the same things as me. It has HL2 Ep2 models (and maybe textures and sounds) compiled with it. The other games are not required to download a map/addon, and upon joining a server with a map with these things that you do not have installed, you will still continue to download the map, however errors will still arise (and you may get script errors, but these usually aren't anything to worry about).ĮDIT #1: Here is the 'funky' texture thing I was talking about:Īlso, there is a Trouble in Terrorist Town (TTT) map called ttt_forest_final. Without the proper textures/models installed, you will (as shown by Timmy Jim) Errors and purple/black checkered patterns, or textures with other 'funky' texture issues, relating to a HDR skybox. Note that most maps do not use this method, as it increases file size and (possibly) decrease optimization of the map, making it run slower.įrom my browsing of the workshop, I have found that usually maps require Counter Strike: Source or Half Life 2: Episode 2. Some addon/level creators have even used custom textures and models that you will not find in any other game. This means that when you download (for example) a map, even though it may have (for example) HL2 Episode 2 textures/models, you are still able to see them properly without the game installed because you have downloaded them with the map. However, all of the escape maps were removed from the game. In addition to the previous answers, it is worth noting that some maps or mods have models/textures compiled with them. Escape mode is a cut game mode that was added in the Counter-Strike beta but can still be played in Counter-Strike and Counter-Strike: Condition Zero. You will see a lot of checkered purple and black objects, and actual 'ERROR' messages like this: A complete list of Source games can be found here.īy not having the correct games, you could potentially be missing the textures needed to play maps created by others. I would say at the minimum, you will need that game (and you might as well get Team Fortress 2 since it's free). and many more! But the majority of the textures are handled with just Counter Strike: Source. It's important to note that some others games that may be needed are basically any game that run on the Source Engine developed by Valve. Team Fortress 2 has been free since June 23, 2011. This Reddit also provides some more details.Ĭounter Strike: Source is currently $19.99 at posting. Please note: Some multiplayer servers and game-modes might require you to own other games - such as Counter-Strike: Source and Team Fortress 2. However, you will need to purchase and download (possibly) Counter Strike: Source and Team Fortress 2 for a lot of the textures and other game objects. Technically - you do not need to purchase anymore games.
