About This Game

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

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 its 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.

As a avid NS1 player (and still actively involved in reviving the NS1 community) NS2 was definitely a great thing, but it came too little and too late, by the time NS2 was in a playable state the NS1 community was nearly gone, and NS2 tried some different ideas, such as power mechanics as well as many other ideas which turned away a significant portion of their playerbase. NS2 might have been a really fun game to play, but we'll never know.
> Back to NS1 for me :D

Unknown Worlds really cares about the games they produce. I played a lot of NS1 and NS2. The community has become smaller but people still play and NS2 usually has a few full servers. It's a great game. NS1 and NS2 are up there for my top favorite games. FPS with aliens vs marines is a good idea. Fighting for resource nodes for upgrades makes the game great. The aliens life forms couldn't be any cooler and more fun to learn. Marines also have there charm as well. Jet packing while shotguning aliens is always a great experience. Hopefully one day Charlie will have made a great successful company and they then will create ns3! (One can dream)

Game was great, but game has a small community now. Apart from that there's the ♥♥♥♥ing devs who added paid skins to their game. Now that's what I call greedy, not to mention lazy.
I could've given this game a 9/10, but since they added skins I'm giving it a nice 4/10.

I haven't played this game in a while, but out of all the games i miss and consider under-rated when i consider playing a game of something after playing a lot of something else, i miss and want to return to this one the most.

The balance has always generally been good, with subtle variations in the aliens being strong early game due to their manouverability and the marines strong late game due to their firepower, i've still found the game very satisfying and playable. Those subtle variations said, the game has never been more balanced and i consider those issues largely addressed as well as they can be.

I enjoyed this game for the short period that i played it in pre-release (not that i can tell i ever had the cool, unique skin you're rewarded for doing so ever being properly equipped when chosen). But one thing to be aware of is there is a relatively high skill ceiling that makes the game quite competitive due to the fact it's very fast pace, quite punishing of mistakes made and rewards fast reaction times and accuracy (the latter one there being a slightly more important skillset for marines).

Playing marines is certainly a lot more easier than playing the aliens, probably largely due to the familiar gameplay. This does result in the marine team filling up faster than the alien one. You might find yourself having played a lot of games as the alien and wanting to swap, but find it difficult to find a slot on the marine team.

Not a whole lot i can really say about the tactical aspect of the game. I do enjoy commanding both teams, though it can be a pain finding a good one when you want to be a player. The alien commander is a little easier on account of being to operate almost indepentently of the players since the structures tend to build themselves if only slowly, whilst the marine commander absolutely relies on his marines for this.

Use of personal requisition is more difficult as marines as an alien player can perform well with even the basic tier 1 class and can happily sit ontop of a pool of requisition waiting to be used. Whilst the marines will want to invest in consumables and upgrades throughout the game meaning if they die they likely wont have that pool of resources to immediately replace their loadout. Some consolation does come in the form of being able to re-acquire your weapon from the map within a certain time period, but that does also come with the potential for being ambushed.

TL;DR It's balanced, it's fun, it's different if not a tad competitive compared to its peer shooter titles.

Quick Review:
Awesome to see the old source mods receive stand alones!
This game was fun for a while but quickly became stagnant. There were many poor developer decisions for a relatively low population game.
There's a cool learning curve for beginner to expert players.
It's mostly in the hands of the community now as the original developers have moved on.
Can't recommend trying it out now. Was at it's best when it was released and everyone was in the same boat/playing field.

Overall Natural Selection 2 had the potential for so much more but ultimately failed.

I loved this game. But it's dead now. Truly dead.
These late gameplay reworks and balance changes are just haphazard attempts to eek out a few more months of life.
At least the rookie servers seem to have populations. I wouldn't know. The fact that there is more life on segregated servers for rooks than vet servers keeps it that way.
The story might be different if you're EU or NA.
But if you're an Aus/NZ player you are well and truly screwed.
Essentially you either play on the one or two non rookie servers that give you 250+ms but don't auto kick high pings -while still being chewed out for a high ping- or you luck out for the 2-3 hours of one night a week where the Aus server sees more than 10 concurrent players.
This game was fantastic.
Rest in Peace, GG No Re.

The game is a mix of a First Person Shooter and RTS (of sorts), but in a good way. The teams consist of a single commander on both sides that will build structures whilst also, taking advatage of his top down perspective, trying to instruct and organize his Ground Troops. Of course the playstyle is diffrent depending on which team for the marine commander needs the Ground Troops to build the structures he placed whilsed the alien commander doesn't need his Ground Troops to do so. The objective is to take out all of the opposing team's Command Stations (Marine) or Hives (Alien).

Because there is only a single commander per team you will likely be spending a large majority of yoru time being apart of your team's Ground Troops.

-As the Marine Ground Troops you will have to communicate with your team to build structures set down by your commander and try to not be killed by the Aliens by trying to engage them at a distance.

-As the Alien Ground Troops you will try to slow and prevent Marine progression and explansion by destroying Marine Structures and killing them yourself. The Marines have Machine guns that are very effective at killing Aliens at range, and as the Alien you do not have range a large majority of the time. This leads to creative ways to try and get to them, from Crawling into the vents to try and flank them to crawling on the walls to ambush them.

*Keep in Mind that the things I just described are the very basics of both sides and the game has much more to it.

Something really nice about the game I would like to note is that there are rookie servers that only new players can join where you can only play with other players that are also realitivly new to the game. So you will never really have this pressure in these servers. Yet when you start feeling comfotable enough to start playing on normal servers you will find many servers will have vey organized teams that create amazing games! It's a very nice system having freindly rookie servers and amazingly organized normal servers.

The only issue I have with this game is trying to practice with commander. When I started becoming proficient with playing commander (online) I was locked out of the rookie servers. Normally this would be a good thing as the game deemed me with enough expirience to start playing on normal servers. Now in these servers you play with a large amount of veteran players, and this left me very little room to practice playing commander. Of course I'm not saying it's impossible to play commander because every once in a while you with find a team with no commander that is very supportive of you being a new commander and will help you do so. But most of the time on the normal severs I was contemplating either: "A. Taking command and being inexperienced and slower and more than likely lose the game for our team because of this." or "B. Letting someone else take command that is faster and more expirienced whilst be part of the Ground forces where I have the most experience in playing."

Either Way I find this game to be overall fantastic and a lot of fun to play. I would recomend this game to anyone who enjoys playing with orginized teams to create amazing strategies and extensive engagments.

Ummm, yes! no other game is like this. strategy driven, team work is what wins games. The commander role is extremely fun as well. This game takes time to master. I have 80 hours and I'm still learning new strategies. Well worth the price tag.

Fun cross between an FPS and an RTS. The only other game that I've seen similar to it was an old game called Savage: The battle for Newerth.

There's an RTS element, with a commander, who focuses on giving commands (although with human players, they're more like requests than commands, as the players don't have to obey them), placing buildings, researching tech, and managing resources.

The players meanwhile play it like an FPS. I prefer playing as a marine because it's fun to shoot down aliens. Although you really have to watch your shots, as it's really easy to miss, and you burn through ammo quick. And if you can coordinate with a few other marines to form a fireteam, you can usually hold your own quite well, even with just basic rifles, armor, and other tech.

At only $10, the game is not expensive, and it offers hours of fun.

NS2 is a PVP shooter unlike anything you have seen.
It doesn't need recoil and spread to make shooting an enjoyable challenge as marine.
As Alien you can dodge bullets like neo or stealthily surprise attack an unsuspecting marine from above
both sides are a real test of your reflexes and mindplay
and if you just want to manage everything you can play Commander, place buildings, unlock weapons and skills: you control how your team should play.

Aliens and Marines have dozends of skills and classes that change the way you play dramatically
become a swift winged beast or a rhino like killng machine, grab a jetpack and shotgun and never miss a shot in the heat of battle or control a mech walker with huge guns and armor.
or just support your team with heals, repairs, constructing or building smaller support structures without needing to command.
There are many ways to individualise your playstyle

The game is to this day being patched and balanced by people from the Community, so it is a very bug free and fair experience (if your teams have comparable gameplay experience of course).
if you are not sure if the game is for you, you should mark it for later, it has been on -75% sale quite often so far. and cheap keys from sales are being sold on other sites as well.

This game is so beautiful and amazing looking. I found this game and instantly put it on my wishlist. It was a rts and fps. I loved the gameplay and everything. I quickly bought a copy for me and my brother. So happy to finally play it. Until I did. It was so hard. As alien I could not kill or do anything. As human I could not even shoot one bullet without missing. You need wicked reflexes and insane skills. I tryed to practice and look at my hours playing. I still can't even win one round. I recommend it to expert players, not the simple player like me.

My score is 80%.
