This article is about the NS2 Servers in general. For the Server hosting and administrating, see Dedicated Server


Natural Selection 2 Servers are mostly community hosted.
List of NS2 Servers


Servers have to be Ranked in order to report Player Skill / Hive Skill updates to change the Skill value.

The Rules for this are as follows:

  • The server should have 12-20 player slots
  • The server will ensure through its configuration that it maintains an equal number of players between the two teams when the server is full. (No 10v9 allowed)
  • The maximum Spectator slot amount for a Ranked server is 5
  • The server should run the ns2 game mode only with mods that have been green lit. A list of greenlight mods can be found at
  • The server should be using VAC
  • The server should use the default consistency check. If you want to use a custom consistency check check configuration please contact a developer for approval in this channel. (we recognize there can be issues in some cases regarding old sound mods)
  • The reported server performance in the server browser needs to be at least "Okay" for 99% of the time the server is online.
  • The server environment should foster a friendly community.
  • The server should not modify, bypass or manipulate the steam inventory (official skins/badges) system.
  • The server should not override a user's skin selection. (if they've selected default green, then it needs to be default green)
  • There should not be any attempt of manipulating the server's query status response (which includes the player details, ping, performance data and game mode) or the hive end-round reports. This includes long term (>30 mins) idle players that are immune to AFK rules and are used solely for manipulating the server's browser ranking.

To apply for Ranking you need to:

  • Ask IronHorse on Discord for access to the #server-ops channel.
  • Read the rules pinned in that channel and ensure you're in compliance.
  • Ensure you've played a few rounds of 5+ minutes, even if its with bots.
  • DM IronHorse your server name, IP and port, and provide him with your SteamID3.

For more detailed requirements checkout the #server-ops channel on the official Discord.

Quick Play

The Quick Play button tries to connect the player to a suitable server that is:

  • on your Skill Level and is filled
  • preferably favourited Servers and Servers with Steam Friends
  • ignores blocked Servers
  • has acceptable performance
  • has an acceptable ping
  • preferably Ranked Server (Non-Ranked will be considered as well)
  • uses only Normal Gamemode

Arcade is an alternative Gamemode that doesn't play by the classic rules or balance of Natural Selection 2 like having more than 10 vs 10.

Consistency Check

The consistency check prevents users from modifying files via Mods or locally in order to prevent people from gaining an unfair advantage.
