Survival of the Fittest: Natural Selection 2



When I first heard about Natural Selection, I thought the concept was a little crazy. Mixing FPS with RTS, Natural Selection 2 is the spawn of Starcraft mating with Unreal Tournament. Players fight across large scale maps as either a Frontiersman or Kharaa. Simply it’s humans against aliens, do you prefer guns or teeth?

The RTS side of the game is the most interesting. There’s one commander per side who locks themselves away in a command structure. They swap their FPS viewpoint for a top down RTS role and gain a new set of abilities. These allow the commander to place structures to expand and upgrade. Whilst also allowing them to give commands to other teammates and dropping them supplies. Taking out the enemy base will stop players from re-spawning after death, leading to success.

Being on the front lines is wildly different for each side. Humans have to rely heavily on their equipment. Starting out with an assault rifle and torch, they are just about a match for the basic alien known as the Skulk. Sticking together is vital; a lone ranger is an easy ambush target. Crucially there is no friendly fire. So as soon as the lead alien leaps out the shadows, you can open fire without fear of hitting a friend. It creates some fantastically frantic gameplay for both sides. Also, backwards movement is quite slow, so you have to commit to entering a room. Scanning the ceiling and vents for any nasty lurking enemies is vital, or you’ll quickly find yourself chewed to pieces.


The mouth-cam of the Kharaa is a curios perspective to play an FPS from. Trying to line up fangs with flesh takes some practice. A glancing nibble deals reduced damage, whereas a solid bite cuts humans to chunks. You’ll spend a lot of time as the Skulk, a fragile, fast moving alien. Its party piece is climbing up walls and ceilings, giving you access to alternative routes and ambushing possibilities. Again it’s an important skill to learn to be an effective Kharaa player. I found it difficult to stick to the ceiling whilst going through bulkheads. I’d often end up falling to the floor in front of Frontiersmen and end up playing the part of living target practice.

Unlike the humans who power up with new weapons and equipment; the alien players evolve into other life forms. Available at the start of the game is the Gorge, a support and construction role. Its main job is to assist the commander by speeding construction with healing breath. It can also place a few defensive structures to slow human players. It would look like an adorable little Hippo if it weren’t for the horrible tentacles growing out of it. The other alien life forms let you take to the skies, play as a phase shifting assassin and spawn as a living battering ram. All upgrades cost you personal resource which is gained from map control and general play.


A good commander is the key to victory. Their priority is to use teammates to secure the resource nodes dotted around the map. These resources drive the teams’ economy, granting quicker access to upgrades, thus gaining the upper hand.  Each side has different base structures which defines the strategy for each team.

The Frontiersman can place structures wherever they please. This allows them to build outposts and hold quiet corners of the map easily. All humans are equipped with a construction tool. Running up to the outline of a building and holding ‘E’ will slowly build the structure. More players will increase the build speed, but you’ll need someone watching your back. A group of distracted humans is dinner on a plate for the aliens. Power is the Frontiersman weakness. If the Kharaa knock out the power source in an area, all buildings stop working and the lights go out! This denies the resource, and creates the perfect environment to use their night vision.


Kharaa are much more limited in their expansion plans. The base has to be linked by a connected line of Cysts. These small glowing orange blobs spread infestation around themselves like a plague. Any structures placed on the infestation will function and grow. But if the Frontiersman break the chain, the infestation will retreat leaving buildings to wither and die.

Controlling the map’s resources and constructing secondary bases is the main plan for both sides. As the game progresses, the resources earned are converted into research and upgrades. This escalates into an arms race as each side aims to get access to its best equipment first. Humans utilise a variety of weapons such as flamethrowers and grenade launchers, as well as jetpacks and devastating mech-suits.


The aliens can evolve into greater life forms, and add to them with unlocked perks. These can allow them to move faster and in silence. On top of that they can gain quick health regeneration enabling some deadly hit and run attacks. Playing as the assassinating Fade, you can move at warp speed when fully evolved. I’ve run straight past targets accidentally due to ridiculous movement and then had to keep going past them to avoid the bullets aimed at my hide.

Overall, the feel of the game is that of a more old-school arena shooter. The reference to Unreal Tournament is very apt due to the fast pace of the game and no iron sights. With a little practice, picking up the FPS role of either side is straight forward. The command role however is very tricky, but equally very rewarding. There’s links to video tutorials within the game which is handy, but it’s a bit annoying to sit through several videos instead of learning through play.


The biggest flaw with the game is that the mechanics lead to a rich-get-richer scenario. When a team is dominating, it becomes impossible to turn a game around through good paly alone. To add to the loosing team’s misery; they have the choice of suicidal attacks, or to sit around and wait for the inevitable. But that is the nature of Nautral Selection 2. To get the most from it, you’ll need to find a server that suits your skill level for more balanced games. The complexity of the game’s mechanics come together to create an interesting, and most importantly fun game.
