The Unknown Worlds website now offers a new update for Natural Selection 2, updating the action/strategy game to version 301. In addition to fixes and changes, the new version comes with a new map that's free to all owners of the game. Here are some details:

Welcome to Caged, the newest official map in the NS2 universe. A throwback to the original NS1 Map by Nelson ‘manah’ Ferryman, Flaterectomy and other community contributors and testers have worked to honor the original but also offer a new take for the current state of play. Caged offers players a fun four techpoint map with plenty of res and unique rooms and corridors for epic combat engagements.

What would a new map be without some other goodies? As a special treat, players who play on caged for two hours or more within the first week of release will unlock a new skulk skin. This can only be earned until June 10, 2016. After this date you will only be able to trade or buy it from players that earned it in the community marketplace. Get it FREE while you can!
