The latest patch for the Natural Selection 2 Beta is now available on Steam. If you have pre-ordered the game it should automatically update on Steam. If you would like to pre-order and get instant access to the beta, you can still do so here.

After the release of Build 174 we learned of some performance problems on the server when a MAC or Drifter moved far outside of the level. Build 175 should fix this problem and we've added some additional checks to help catch this type of bug in the future. We managed to get in a few other changes as well; the complete change log is below.
