10 FPS Games Where You Fight Aliens

There are quite a few FPS games where you fight aliens or where aliens invade Earth. We cover alien FPS games from iconic sci-fi military shooters to cooperative bug-blasting and full-on horror survival. Fighting aliens in a first-person shooter hits differently from fighting humans or zombies. They are more sophisticated, usually armed with weapons, and can think; unlike zombies, who are dumb but equally fun to kill. Whether you want a classic campaign, a co-op grind, or something that genuinely unsettles you, these alien fighting games are the best the genre has to offer.

1. Halo: Combat Evolved

Halo: Combat Evolved helped establish the Halo series as a major name in console FPS games. Probably one of the best games if you love fighting aliens that are a big part of the experience. The Covenant is a religious alliance of different alien species, each with its own characteristics and combat roles. Grunts are generally easier to defeat, Elites are more capable combatants, Hunters are heavily armored opponents, and Jackals use energy shields to protect themselves.

The gunplay, vehicle combat, and level design remain central to the game's appeal. Its campaign takes you across alien installations and other locations while gradually revealing more about the conflict between humanity and the Covenant.

2. Half-Life 2

Half-Life 2 takes a different approach to alien combat in an FPS game. Rather than focusing exclusively on alien creatures, it places you in a world occupied by the Combine, an interdimensional empire that has conquered Earth.

The Combine's forces include human soldiers working for the occupying regime, alongside alien and other non-human entities. This makes combat more varied than simply shooting one type of extraterrestrial enemy. You must also contend with hostile creatures, including Headcrabs and Antlions, as you explore the game's environments.

3. Deep Rock Galactic

Deep Rock Galactic is a cooperative alien FPS game where you and up to three other players roleplay space dwarves working for an interstellar mining company. Your mission, should you choose to accept it, takes you into hostile underground environments where alien creatures, including Glyphids and Mactera, can attack in large numbers.

The procedurally generated caves make exploration and resource collection a major part of each mission. You can choose from four classes: Driller, Scout, Gunner, and Engineer. Each has its own equipment and abilities, encouraging you to coordinate with your team rather than rely entirely on firepower.

The game combines mining, exploration, and combat, with missions that can quickly turn chaotic when alien swarms arrive. If you prefer fighting waves of alien creatures with friends instead of tackling a traditional single-player campaign, Deep Rock Galactic is a strong choice.

4. Destiny 2

Destiny 2 features several major alien (enemy) factions, including the Fallen (also known as the Eliksni), Hive, Vex, and Cabal. Each has a distinct appearance, background, and combat style. The Fallen are a technologically advanced species, the Hive are an ancient species associated with Darkness, the Vex are a machine-like species, and the Cabal are known for their military organisation and heavy weaponry.

Its weapon variety and movement abilities give combat a different feel from more traditional military shooters. The large selection of weapons and activities also gives you plenty of ways to customize your approach to combat. If you enjoy fighting alien enemies while collecting equipment and improving your character, Destiny 2 is worth considering. Keep in mind that access to its expansions and some activities depends on which content you own.

5. Crysis 2 and 3

Crysis 2 and Crysis 3 feature the Ceph, an advanced extraterrestrial species whose technology and combat capabilities pose a serious threat to humanity. The Ceph have a long history with Earth, and their awakening plays an important role in the events of the series. Skip the first one, but we highly recommend playing both Crysis 2 and 3 if you love fighting aliens in a game.

Both FPS games with plenty of aliens to shoot put you in control of a Nanosuit-equipped protagonist. The suit lets you approach encounters using abilities that support stealth, increased strength, and enhanced speed. You can engage enemies directly, move through areas undetected, or use the environment to gain an advantage.

If you enjoy FPS games that give you different ways to approach combat, both titles are worth playing. The Crysis Remastered Trilogy includes remastered versions of Crysis, Crysis 2, and Crysis 3, making it a convenient option if you want to experience the series on supported platforms.

6. Aliens: Colonial Marines

Aliens: Colonial Marines is a first-person shooter game set in the Alien universe. You play as a Colonial Marine investigating events connected to the films, visiting locations such as the Sulaco and LV-426. The Xenomorphs are the main threat, forcing you to fight your way through hostile environments while using weapons and equipment inspired by the films. The setting includes familiar elements such as pulse rifles and motion trackers, helping establish the atmosphere of a Colonial Marine mission.

The game received mixed reviews, so it is worth approaching it with realistic expectations. However, it offers a campaign that can be played cooperatively with up to four players, giving you the option to tackle its missions with friends.

7. Aliens vs. Predator

Aliens vs. Predator lets you experience three separate single-player campaigns, playing as a Colonial Marine, a Xenomorph, and a Predator. Not only do you get to shoot aliens in a fast-paced action game, but you can also play as an alien. Each campaign offers a different perspective on the conflict and changes how you approach combat. The Marine campaign focuses on survival, with limited visibility and encounters that can quickly become dangerous. As a Predator, you can stalk enemies, use advanced tracking equipment, and attack from advantageous positions. The Xenomorph campaign takes a different approach, allowing you to hunt your targets using the creature's movement and combat abilities.

For fans of the Alien and Predator franchises, this is a good option if you want to experience both sides of the conflict rather than fight only one type of enemy.

8. Prey (2017)

Prey is a first-person shooter sci-fi alien game that combines shooting, exploration, and immersive sim mechanics. You wake up aboard Talos I, a space station overrun by the Typhon, a hostile alien species with a range of abilities. One of the most unsettling enemies is the Mimic, a small Typhon that can disguise itself as an ordinary object. This makes searching rooms more dangerous because objects that appear harmless may turn out to be enemies.

As you progress, you acquire weapons, tools, and abilities that let you approach encounters in different ways. You can use direct combat, stealth, environmental hazards, and the station's resources to overcome threats. Prey places considerable emphasis on exploration and experimentation rather than forcing you down a single combat route. The station is also designed to encourage backtracking as you unlock new abilities and discover alternative paths.

If you enjoy FPS games with alien enemies but prefer a slower, more deliberate experience than a conventional shooter, Prey is an excellent option.

9. Resistance 3

Resistance 3 is a first-person shooter set in an alternate 1950s America where an alien invasion has brought humanity to the brink of extinction. You play as Joseph Capelli, a survivor travelling across a devastated United States while fighting the Chimera, an alien species that has transformed much of humanity into monstrous soldiers. What makes Resistance 3 stand out is its bleak atmosphere and focus on humanity's struggle to survive. The combination of intense firefights, disturbing alien designs, and a post-apocalyptic setting makes it a strong choice for anyone looking for an FPS centred on fighting alien enemies.

10. Doom Eternal

While traditionally framed as demons from Hell, modern DOOM lore expands the conflict into a cosmic war involving ancient aliens (Argent D'Nur) and the biomechanical, angelic extraterrestrial race known as the Maykrs. DOOM Eternal refines first-person combat into a hyper-kinetic combat loop: flames for armor shards, glory-killing for health, and chainsawing fodder for ammo. It is the fastest, most brutally responsive alien-slaying shooter on modern hardware.
