Matchmaking services for Sierra titles including Tribes 2, the Homeworld series, and No One Lives Forever 2 will be taken offline on November 1 according to a Sierra forums post spotted by Eurogamer.

The multiplayer functions of the games will still work but server browsing will no longer be available nor additional community features like Tribes 2's clan support. Online multiplayer in games will still be playable but players will have to use direct IP connections to servers or use third-party server browsing software.

No reason was given by Sierra for taking down the servers. Local multiplayer will be unaffected in any of the 21 titles being taken offline. The list, reproduced in full, is as follows:

• Alien vs Predator 2
• Arcanum
• Caesar IV
• Dark Reign 2
• Emperor: Rise of the Middle Kingdom
• Empire Earth
• Empire Earth 2
• Empire Earth: Age of Conquest
