Update 303 Released!

Happy Summer Marines! We are ushering in the sunshine with update 303. This is a lighter patch focused on some bug fixes and a couple tweaks and additions to the game. With this update we are introducing a new post-round feedback system, this will help provide us with more details about your games and comparing round data to support future changes.

The last six months has seen a lot of changes and experimentation to the game and we aren’t done yet. We are working on developing plans over the next week to continue to build on the new foundation that we’ve created over these last few months. Be on the lookout for some exciting new opportunities and changes to come.

As always, thank you for being part of our community and your continued support of our team.


Tweaks / Improvements

  • Added a round feedback UI – Help us to improve the game based on your feedback
    • Rate the last round you played
    • Select multiple reasons on feedback based on rating
  • Added new Achievement “Arcade Champion”
    • Explore for at least one hour the various community made custom game mode which wait for you in the Arcade section of the server browser:
      • Faded
      • Gun Games
      • Siege
      • Last Stand
      • Defense
      • NS2 Large
  • Removed all outdated tip videos in the training menu
  • Updates the “VS. Bots” tab of the training menu
  • Commander bots can now generally be replaced by entering the command station
  • Restored the spawn animation of eggs (broke a long time ago)
  • The spawn animation of alien structures is less obscuring now by lowering the size of the initial infestation blob
  • Fixed that parasite never timed out if an entity was outside the relevancy distance
  • Fixed a bug that stopped the scoreboard from showing up after connecting to a server
  • Fixed an script error which occurred when you used escape at the tundra unpack menu
  • Fixed that the cancel button of the tundra unpack menu wasn’t functional
  • Fixed Gorge structures not being destroyed in warmup mode
  • Fixed various in-game tooltip descriptions (e.g. power surge, contamination and mines)
  • Fixed a bug that would sometimes cause a research button for a commander to permanently disappear — forcing the commander to either let someone else start the research, or return to ready room to reset it.
  • Fixed that marine upgrades stayed available after an arms lab has been power surged
  • Power nodes no longer play the flinch animation and buzzing sound when they are infested but their armor is gone. However, the lighting in the room will continue to flicker to indicate the power node is infested.
  • Power nodes will now be properly infested if they are rebuilt from death in an infested area.
  • Cysts will no longer “flash” infestation right before it begins to spread.
  • Fade stab will now work even after switching to a different weapon mid-stab.
  • Marines can now immediately shoot upon spawning from infantry portal — they no longer play the rifle deploy animation. IP-biting skulks beware!
  • Marines will now always look in the proper direction after using a phase gate. Before, having previously used a gorge tunnel would cause the view angles to be different.
  • Command station will no longer leave behind the login screen after being killed.
  • Fixed Gorge tunnels and Phase Gates are deactivated during the concede sequence.
  • Fixed exiting a hive or command station, the commander will now face the direction they were facing when they entered.
  • Fixed that bots were counted as human players by the concede and commander eject vote
  • Fixed various script errors caused by the Marine commander bot

  • Tram (Thanks Zavaro!)
    • Fixed the Occlusion Geometry in Shipping around the door towards South Tunnels
  • Fixed a bug that would cause the displacement tool to crash the editor.

About This Game

Natural Selection 2 pits alien against human in an action-packed struggle for survival. Wield devastating weaponry as a Frontiesman marine, or become the xenomorph as a deadly. Kharaa life-form.

Strategy Meets Shooter

Natural Selection 2 is a First Person Shooter and Real Time Stategy game rolled into one! Each team, alien and human, has a Commander. The Commander looks down on the battlefield and issues orders, places structures, collects resources, researches technology, and deploys abilities.

Here are some gameplay examples: A human Commander could drop health packs and ammunition to a trapped marine squad, and deploy sentry guns to help them defend their position. Or an alien Commander could grow a new Hive to spread infestation throughout newly captured territory, allowing more alien eggs to spawn...

Two Unique Sides

Aliens players choose to evolve into one of five lifeforms: The fast, fearsome Skulk can run on walls and deliver massive damage with is jaws. Lerks fly and deploy gasses to support their teammates in battle. Gorges heal other lifeforms and build tunnels, hydra turrets, walls, and other tactical structures. Fades blink in and out of battle, picking off marines with giant scythes. Finally, the giant Onos is so massive and so tough, that even entire marine squads can't take it down.

Marines wield rifles, shotguns, grenade launchers, pistols, and other weapons. Cluster grenades can clear ventilation shafts of sneaky Skulks, flamethrowers make short work of alien structures and infestation, and boosts dropped by the Commander increase combat effectiveness.

When attacking on foot doesn't cut it, marines can construct hulking Exosuits wielding miniguns and railguns, and equip jetpacks for high speed assaults on alien Hives.

Long Term Development

Natural Selection 2 receives constant updates. This year, 2016, Unknown Worlds continues to develop new features, content, and improvements.

Mod Tools Come Standard

Natural Selection 2 comes with all the tools we used to make the game. All game code is open source. That means you can create, and play, an endless variety of mods. Publish, share, and download mods from the Steam Workshop, and automatically download mods when you join modded games.

This game is fun and lives up to its 10$ price tag. With freinds this game can be a blast and evenmore fun when your team has a good commander.

Buy this game and you will have tons of fun.

PS: Dont buy skins on the market, unless you want to waste money!

Ok, so this is gonna be the first game that i´ll ever review. Can i recommend it? The answer is pretty short, yes i can. It has one of the most interesting game ideas ive ever seen and a pretty good graphic. The gamplay feels nice and smooth, the atmosphere is really great and both races (Marines and Aliens) are pretty even so no race can be called op. Personally i like the community (sure there are always some people that behave like idiots) and would love to see new players in Ns2.
So if you read this and consider buying it, i can only say that these are some well invested 10 euros. And if youre able to get this in the summer sale for 5 euros why are you not playing already?

For people that dont like reading: Should you buy it? -yes you should.

cheers Syntexx

Good game, hard for new players to get in to, but good for keeping your twitch and FPS skills sharp. You can usually find teammates to work with if you want to do something fun or interesting, and the community is nice and mature besides a few toxic players and pervasive stacking. As a long time player, the new changes are really good, I don't even like playing on the server that is still on 'classic' mode. Recommended if you like a strategic team game that challenges your twitch skills.

Came back after awhile to see that the devs are still supporting the game. Really happy about that and glad to see all the help for newer players. I heard the game was toxic from elitists but haven't really experienced any of that as yet. Game runs much better than I remember and is a very solid and unique experience from both sides.

Natural Selection 2 is a really good game. It is a MOBA like where the ennemy team has to destroy all of the ennemies command things to win. It is a multiplayer game wich you either play as a marine or an alien. Both teams have a commander that has a top down view, while the other players play in first person. The marine commander supplies the marines with ammo, health packs, weapons , etc and can put infrastructures as an armory, a tech machine thing, "generators", etc. While the aliens commander puts dow pods that create infestation ( that is nescessary to build aliens things ) and other structures that inhance aliens stats ( for some ). I tried to describe the better I could but you should look it up on Youtube to have a better look at what it really is.

Game is unique and amazing to play, the newest updates really brought it to life with great refinement. Too bad very few people still play it with very few servers, at least inside the acceptable ping for my region. It still is a great competitive team vs team game.

This used to be my favorite game. For 3 years, I played this game religiously and logged as many hours as I had in CS:S and TF2 previously. At a time, I would have rated this game much higher than both of those AAA titles. Sure, the public servers were always and still are a bad case of teamstacking due to a lack of in-game matchmaking or a proper team skill balancing system, and the game released full of bugs and was terribly optimized leading to an immediate and huge dropoff of players and dooming the game to a tiny community for the rest of it's existence... but the core game was an excellent foundation, and over the years with the help of the balance mod "CompMod" and "Pub Friendly Comp Mod" by Dragon as well as key quality of life mods like "NS2+" by mendasp and "Shine" by Ghoul (not to mention some long needed bug fixes and optimization), the game became great. The greatest game I ever played.

But not anymore. I can no longer recommend this game for anyone. Not for any price, not even if it was free; I wouldn't wish this abomination of a game upon anyone.

The developers (UWE), in some misguided attempt to help "new player retention", using some bizarre reasoning to "help the game grow" have actually started killing their own game. The most popular servers for the last 3 years, now dead. The one league there was for this game: dead. The games only competitive matchmaking system (NSL gathers): dead. The amazing mod "CompMod" mentioned before? Dead, with random features from it stripped and screwed with and thrown into the vanilla game in a poor attempt to "shake up gameplay".

The developers of this game have ignored the community for so long, and their continued ignorance has now ruined the game for me, and so many like me. F*ck UWE. F*ck NS2.

UWE: The balance is f*cked, and NS2's most loyal players are quitting and moving on, the majority of the remaining community hates you and your most dedicated and essential modders are sick of dealing with you. Revert these awful changes, and actually SUPPORT YOUR COMMUNITY or watch this game wither and die.

Devs killed competitive and continue killing major communities in this small game

Edit for KeiserSoze:
It's a good game, and I doubt I'll ever find anything to replace it. But it's the sad truth that the current devs are doing anything they can to destroy the few small communities left in this game, in an effort to retain NEWER players - which is doomed to fail anyway.
Also, it's not really the game itself that's good, in fact it would be ♥♥♥♥ without the changes made by some awesome people in the ns2 community. It's the concept of the game which is the best and most addicting I've ever seen. w/e ggs no re

I have played this game for over 2k hours and the devs have completely sucked all fun and skill out of this game, not too even mention the fact that this game still runs like ♥♥♥. Dont waste either your money or your time in this game like I did. There are barely any players left in this game so that means you keep running into the same people every time meaning you almost always know how the game is going to end which is not fun. You can check the player numbers here for your self http://steamcharts.com/app/4920 end see that many players are also leaving.

Ahhh. NS2. The perfect combination of RTS and FPS. I have spent hours doing pretty much everything possible in this game, sans competative play. From shooting aliens to chomping marine scum, I have had the pleasure of playing NS2 for a while, through its low phase of small player count, and into what is now a fine time to purchase the game, as people are once again active and the servers are finally occupied. NS2 to a stranger hosts a team of marines, who play a standard (from a control standpoint) FPS game with a birds eye RTS commander, and a team of aliens with their own RTS commander. Both teams struggle to earn resources, both for the commander to place structures and assistance to players (tech, medpacks, etc), and for the players who need to buy weapons and stronger aliens. As the marine experience is more standard, and is not the most unique and in need of description part of this game, I will describe only the aliens in more depth to save you time reading this. The free one (the skulk) walks on walls, the others include a flying bat like creature with poison bites and spikes, a blade handed creature who can "teleport" short distances, a tubby hippo with healspray, and a giant gorilla rhino thing. The learning curve is steep for marines, steeper for aliens, and the steepest for commanders, but once past it, the game opens up into a unique, unforgettable experience.

Here is what NS2 is to me though:
-Crawling through an airvent as a marine and ♥♥♥♥♥♥♥♥ yourself when a cloaked skulk bites you and you spray and pray like nothing else.
-Running away as a gorge from a marine that is pelting your behind and begging your teammates to save you.
-That one guy who buys a flamethrower and everyone judges.
-Beginners learning how to play as a higher alien lifeforms and thinking they are immortal (spoilers, they are not).
-That marine who gets his exosuit for the first time, then screams "I NEED WELDS" when he loses 15 HP.
-Commanders who care about their teams and strive to win, yet lose respectfully (most of the time).
-A community that makes the stereotypical FPS community weep in jealousy...so many people who aren't pointlessly disrespectful and irritating.
-Rookies (and people in general most of the time) who listen to advice, play hard and have fun. No matter what.

In short, I 100% recommend this to anyone who enjoys strategy, FPS, and gaming with people who are mature (most of the time), intelligent team players, especially if in need of a unique twist or change of pace.

After spending 3,500 hours in NS2 (more than I've ever spent on any video game), I have found only one major game-breaking flaw: the recent misguided efforts of developers working within a vacuum to actively shake up the core gameplay has made it impossible to beat the final boss (The Hughnicorn) on the last level so you can't even save the princess and finish the stupid game. It is deeply saddening to think of all the quarters I have pumped into this machine and will never even get to see the end credit sequence.

The ultimate tactical shooter + strategy game. Though it has it's problems. Get on sale.

This game is just really fun to play. It's very tactical, matches take long if done right and it's pretty balanced.

The problems are: it runs pretty bad, it's not very accesible.
Make sure to watch some introductory video's !! not just play the tutorial !!

This game is hard to learn.

I give it a 7/10 (better than CS:GO)

Excellent FPS-RTS-hybrid with a strong focus on the FPS part. Initially you have to invest some time since there is so much stuff to learn about, but it is very rewarding afterwards. Certainly one of the best games I know.

Product received for free
this game is onestly one of the most amazing team co-oparation games you can buying in 2016, because unlike other types of games, this game doesn't use microtranactions to make money or add a large amount of dlc, instead they use skins, which do no imapact effect on the gameplay (well the Reaper Onons is something you would'nt want to see uncloking right in front of your face!)
this game is saidly losing it's players fast and the only main way you can find a full server is by looking for almost full ones or joining other lanuage based servers.
mastering the aliens and understanding the commanders on both sides is also just as fun as been two shot via stalkers at the start of the game.
this game has a lot more potenial, but the gameplay makes it a bit of a boring game, sure it's fun but over time the only way you can get the most fun out of it is by playing with friends, all on the same server on the same/different teams on a skype call. (also the lack of weapons is annoying, because in the trailer a marine has a grenade launcher attachment on his rilfe, so that makes me think that they need to add more content onto this game, such as turret upgrades, more marine upgrades,more aliens and different hive parts and so much more)
but over all i would recomend this game if you like real time games and no recoil gun games or pogostick alien simulators!

As I've often summed up (since the days of NS1), this is like the first person shooter version of a StarCraft battle between marines and the Zerg.

In Natural Selection 2 it's not all about twitch reflexes (though this is faster paced than most); victory requires dynamic strategy, tactical combat, communication and team work.

The strategic element to this game makes it a unique gem. It's far more engaging and complex than anything offered by Battlefield, Team Fortress, Counter Strike and similar games.

The community isn't huge, but this game has no equal. Highly recommended.
