"Natural Selection 2 is a genius mash of CS and SC2." -

Natural Selection 2 is an immersive, multiplayer shooter that pits aliens against humans in a strategic and action-packed struggle for survival. It seamlessly combines shooter and RTS/strategy gameplay.

Key Features:

  • Two Unique Sides: Whether you play as one of the elite marine Frontiersmen or the vicious alien Kharaa, you must use unique strategies and your abilities to win. Marines form persistent squads to find and destroy alien hives. Aliens can choose a wall-running Skulk, pudgy Gorge, flying Lerk, murderous Fade or gigantic Onos that can smash through doors.

  • Real-time Strategy: Commanders play from overhead to lead their team to victory. Build structures anywhere, collect resources and research upgrades. Marines buy weapons at an Armory or build sentry turrets and siege cannons to assault the enemy. Aliens build upgrade chambers, evolve special abilities and plant traps.

  • Dynamic Environments: Use a flamethrower to clear the spreading alien infestation. Aliens destroy power nodes knock out the lights and power down marine structures. Random start locations mean you must scout your enemy and before committing to a build. Every game is different.

  • Unlimited Variations: WYSIWYG graphical tools and powerful scripting allow you to create new weapons, scenarios or entirely new games. You’ll get all our tools (level editor, cinematic tool and more) as well as the full Lua source code to Natural Selection 2. Version 1.0 is just the beginning – ongoing automatic updates keep the game fresh by adding new maps, weapons and abilities. Steam Workshop support and auto-downloading makes playing and distributing mods automatic - and gameplay always fresh.

Jet packs and alien rhinos.

Natural selection 2 may be one of the funnest game I've played last year with its expansive gameplay quality. At pre-game, you can decide which of the 2 races to play as from Aliens or Marines both having there advantages and disadvantages.

With both races 1 player must take command, think of it as battlefield 4 commander mode, with 1 player taking command on each teams, they must assist each of their team members to build structures to push back the enemy back while reciving points to upgrade you're teams aresnal that include new armor upgardes, weapons and and JETPACKS!!!, the samething happens to the Alien team except your given an option to metamorph into a new species, each species having a set of unique ablitites, so if you ever wanted to fulfil your dream of being an alien rhino now you can.

As for the gameplay, the controls feel smooth and very reactive like a twitch shooter suppose to feel and anyone new to twitch shooters it may take a while to get use to. Another thing you'll be trying to get use to if you're new to the game is the difficultly curve because it may be troublesome for you not knowing what to do during the middle of the game from experience it did not go well.

The duration of the matches can be very lengthily taking up to 1 to 3 hours if both of the teams are equally matched but if you have not very experienced commanders it may take 30 minutes to win a match, this game can suck so many hours out of you're day, you'll be wondering where you're went.

And don't forget to have fun and play with friends it makes the game more fun to play.


Lacks a Large Population but Great Fun

ROKET | Dec. 26, 2013 | See all ROKET's reviews »

This game is great and the best team based game Ive played since Team Fortress 2. The only problem is that the devs didnt move fast enough to promote and support the game. It released as a generally unoptimized game but has since been fixed to not only perform well but also invite players in. Yes it has a learning curve but its very easy to get into.


This game is solely multiplayer. There are two sides to the battle and each side is very different. One side, the aliens, are very organic and utilize a zerg like creep to spread across the maps. There are a few different maps and each provide different environments to choose from. The second side are the marines. These are your typical space marines and they sport mostly generic weapons. It isnt until higher tier tech is unlocked (through your commander) that you get the awesome stuff such as mechs or in the case of the aliens, giant rhino like creatures that tear the marines apart.

Overall the gameplay is smooth and even better now after the various content updates that the devs have released. The game also runs more smoothly and with less lag than it did at launch.

The best of the game is the commander which overlooks the battlefield aiding his marines in battle. He also sets up the base and other outside structures that help the marines, or the aliens, progress through the map. The game ends when either all the hives or command posts are destroyed.


The marines have a mostly generic look but the graphics and textures are really smooth and nice (especially with SweetFX). The beauty in the game resides with the aliens, however, and they are a site to see. When creep has spread and structures are built a map becomes another world. The aliens also sport the most interesting HUDs and character models.

Overall this is a great game: 85/100


The true aliens experience.

Many people will remember watching the film 'Aliens' and wishing that there was a game that accurately recreated that atmosphere. Unfortunately, most of the actual 'Alien' games have failed to do so. However, Natural Selection 2 is as good as it gets for the genre. Both the creatures and the humans feel fun to use, but both are played in different ways. There is a great element of strategy involved, as if you split off from the rest of your team, or attack at the wrong moment, or as a human, if you wander off by yourself, you will probably die quickly. Adding to the strategy is the fact that both teams have a commander, so fans of strategy games such as Starcraft will feel at home in this role. If not, then there is no need to do it and you can just be a normal soldier or alien. The game also looks excellent and the environments are brilliantly designed. I would highly recommend this game to anyone.


Natural Selection II - review

Natural Selection 2 is a first-person shooter mixed with a real-time strategy that sees soldiers opposed to terrible space aliens. Each side has its own peculiarities and can evolve in different ways during the game . The player is then called to create a strategy much more complex than a normal shooter , because he has to manage the future of the match, studying the situation and choosing which evolve your creature alien, or what weapons to use in combat with the soldier . There is also the role of the commander , or a supervisor of the team that has a very important role : manage tactically attack and defense. Through an interface is not very easy to master, the player / commander must monitor the map , giving instructions to the team via microphone , distribute healing items , directing scientific research, build various structures and so on. It is a game in the game. Natural Selection 2 requires the development of dear old skills, but also requires the ability to reason about their moves without the fray .


Cinematic Fun

landsharky | Oct. 18, 2013 | See all landsharky's reviews »

I've found that when games try to portray/create the classic aliens versus marines scenario there always seems to be something lacking, something that doesn't make it feel real. Search no more my friends, this game captures truly cinematic moments that feel as if you are fighting for dear life to fend off waves of aliens. It's not just the marines, when playing as aliens you can feel the power you are capable of the second you spawn but also how easily that can be taken away. Both factions feel complete and balanced offering a slough of items, abilities, maps, and mods at your disposal for countless hours of fun and re-playability.

Initially the game will take some getting used to but the community is by far the best I have encountered and are more than willing to guide you along every step of the way.

Get this game.
