Sometimes in conversation, the question arises of what a player would do if they were to ever see aliens. If video games have ever taught a player anything it's that it all depends on what type of alien and what they were doing interacting with humanity. Some video games make it so that aliens are horrific evil creatures while others give players a mixture of both kind and malevolent beings.

The games on this list will feature aliens as either the main character that the player plays or have aliens as the main villains in their story. The games will not belong to any genre of the game specifically. These games are some of the best in both their design and the threat that they present.

10 Destiny 2

Destiny got a lot of flack when it first came out as the story felt unfinished to a lot of players and the game did not seem as large as what was first promised. The addition of many expansions made the game a lot more enjoyable, but critics still felt that the game should have had a lot of the content it added with the expansions when it was first released.

Destiny 2 fixed all of those issues by including an immersive story with the base game and then continuing its trend of making great expansions that add new alien enemies as well as alien bosses. Each alien race has deep lore that explains the complex systems that they use to run their societies. The game is dense in creating its different alien societies.

9 Alien Isolation

Xenomorph From Alien Isolation

Making Alien Isolation a survival horror felt like a true homage to the original Alien movie. Alien Isolation lets players experience the fear that the members of Nostromo must have felt when being hunted down by the Xenomorph threat of the movie. The game inserts plenty of scares and has moments like the Alien ripping through one of the vents and killing the player that provides some frightening but memorable instances.

The game can feel like it drags on for a little too long. It basically plays like a giant game of hide and seek with missions littered about and there is only one enemy. That being said, the tension that the game creates through different encounters with the Xenomorph is worth the play.

8 Destroy All Humans! 2: Reprobed

Destroy All Humans 2 Reprobed

Aliens wanting to destroy the world is a common trope that occurs in video games but usually as the antagonist. Destroy All Humans! 2: Reprobed is the most modern Destroy All Humans! rendition and it lets the player take control of the alien bent on world domination. It is a destruction sandbox game that lets players try to wipe out humans using different arrays of weaponry.

The game's story falls flat, but flattening buildings with a powerful UFO and abducting humans with a tractor beam is still a lot of fun for those that have never played any of the Destroy All Humans! series.

7 Spore

Spore Different Creatures

Spore tells the story of an alien species evolving. It does that by starting the player off as a microscopic organism, then evolving them into an aquatic animal, after players gain the ability to walk on land through evolution, then they begin to gain sentience as their creature forms a tribe, subsequently they create a civilization, and then travel into space to colonize other planets.

The game is neat with every different stage of the game playing differently like the microscopic stage having a mechanic where players must eat to grow bigger and the city stage playing like a real-time strategy game and city builder.

6 Mass Effect 2

Mass Effect 2 has to be one of the best games in the Mass Effect series as well as in gaming due to the fact that it has an engaging story. The gunplay felt a little off in the original make of the game but Mass Effect 2 Legendary Edition made the mechanics a lot less wonky when it came to aiming and shooting at enemies as well as the game's cover system.

The game focuses on players building a team to take out the alien threat that is trying to wipe out humanity. There are plenty of different alien races that players encounter in Mass Effect 2 each with their own personalities that make them feel as though they have different cultural backings.

5 Halo Infinite

Halo Infinite made small changes to the franchise that ended up benefiting the series overall. Some of these changes include the campaign that was the first time that the game had ever taken place on an open world map. The open world map felt like something that the series had always been missing.

The game is full of different alien types that the player must go against such as the Skimmers as well as a boss called Jega 'Rdomnai who dual-wields red energy swords and has the power of invisibility.

4 The Eternal Cylinder

The Eternal Cylinder Gameplay

The Eternal Cylinder takes place on an alien planet with alien creatures that looked like a cross between surreal art and 3D animation. The game actually works as a survival adventure game with a looming threat that is constantly nipping at the player's heels. That threat comes in the form of a giant cylinder that is stopped by anchor towers that give the player momentary respite.

The player must then uncover mysteries and go around the map looking for food that can help their alien companion evolve.

3 XCOM 2

XCOM 2 Gameplay

XCOM 2 is a strategy game where every single decision that the player makes matters. The turn-based combat makes it so that players have to think about how they will take out the aliens and if they lose a unit then that unit is gone for good. This will make it so that units that the player likes or has spent more time with will be more cherished by the player.

The game revolves around the world being taken over by aliens. The way that this alien invasion is done feels a lot more like a threat to the Earth in the game than in other alien invasion games. This is because the aliens have a victory counter that goes up every time they capture a new location ad down as the players take more objectives.

2 Dead Space 2

Return To The Ishimura Level With Isaac In Dead Space 2

Dead Space 2 has a lot of survival horror elements but also works like an action-adventure game at times. This is because the game has it so that the player has moments where they will have enough ammo to rip the Necromorph alien enemies apart, but there will be other moments where the protagonist, Isaac, will be running for dear life trying to collect supplies.

The only purpose the aliens in this game serve is as a horrifying threat to Isaac. There are tiny baby aliens that have long appendages that shoot needles and big ones that look pregnant due to the fat build-up on their bodies. The designs are disgustingly delightful to encounter.

1 Half-Life 2

Headcrab Enemies In Half-Life 2

Half-Life 2 took the concept of the first game which was full of environmental storytelling and alien encounters and then rolled through a dictatorial alien-invaded Earth on top of it. The entire story of the game is filled with alien drama as the second game takes place when the previously enslaved alien slave race called Vortigaunt has fled to Earth but the evil Combine, an evil intergalactic empire, has taken full control of the planet.

Half-Life 2 combines this alien drama with enjoyable combat that will have players taking down giant enemy robots and crawling through head crab-infested levels.
