Natural Selection 2 build 238 improves shotguns, slows down goo, and teases large content update


Another update for Natural Selection 2 has rolled out through Steam. Build 238 and build 239 (I’ll get to that) are maintenance updates rather than content drops but they make a couple of changes that should please the marines. Mainly, the shotgun has been improved removing any element of luck from the bullet spread and the speed of alien’s goo spit has been decreased making it a less effective long range weapon.

More changes below and news of the content drop later this month. Oh, and that mysterious build 239.

OK, so the major updates in 238are all contained in this handy little video but I’ve posted the full change log down below:

Unknown Worlds hint at the larger content pack which is coming later this month and will come packed with a new map, Descent.

Now, Build 239. It’s a wee’un. Essentially, build 238 introduced “A nasty bug” that allowed “Aliens to evolve all traits at once.”While the Alien players were happy the marines were less thrilled. As well as patching out the bug, build 239 also optimised the game’s animations saving memory for everyone.
