Halo Combat Evolved and marked a revolution in the world of FPS and Sci-Fi action games. It’s always safe to go back to the originals in the case of sci-fi, for most of the new games have drawn inspiration from them.

Nothing special, just another day of intergalactic battles that may exhaust you but are equally fun! It’s remarkable how the original game continues to deliver in terms of gameplay and remains thoroughly enjoyable in its campaign, even after more than twenty years.

12. Soma

SOMA Cover

Metacritic Rating: 84

Other Platforms Supported: PlayStation 4, Xbox One, macOS, Microsoft Windows, Linux, Mac operating systems, Classic Mac OS

Topically, this may seem like another title like Alien: Isolation, yet upon playing in-depth, you realize why this is among the top-ranking sci-fi classics. Frictional Games, the developer behind Amnesia: The Dark Descent, has also crafted and launched SOMA, a science fiction horror video game. 

But who wouldn’t be scared if mysterious events started occurring underwater on a weirdly isolated research facility, PATHOS-II Let’s? Just say that, like your relationships, this game keeps getting more and more complicated. Not only are there evil monsters and insane machines, but there are also corrupt people that you’re forced to deal with. And, at the end of the day, your wits are what ultimately save the day in Soma

The first-person perspective significantly enhances the experience as it effectively conveys the claustrophobia and paranoia that the game aims to instill in players, making it a fitting choice.

11. FTL: Faster Than Light

Metacritic Rating: 84

Other Platforms Supported: iOS, Microsoft Windows, Linux, Mac operating systems, Classic Mac OS

You’re running a spaceship and in outer space; oh wait, you’re against the clock to save the galaxy! These life-threatening missions and unique problems with solutions only you can come up with pretty much make up the FTL: Faster Than Light experience! (The barrage of missiles was totally uncalled for, btw, but such is FTL, and you will have to deal with it inevitably!)

Your spaceship might not exactly come in handy while playing, for it can throw challenges out of the blues sans any anticipation. You can either re-route your engines or rewire things to aid the process of making it live on time. While the gameplay mechanics might seem confusing to a rookie, a sci-fi player or a Star Wars/Star Trek fan would definitely find Faster Than Light worth a shot!

The makers of the original series decided to try their hands on a new concept, only to come up with this Science Fantasy masterpiece. The game and characters both come alive in this action-adventure RPG.

4. XCOM: Enemy Unknown

Metacritic Rating: 89

Platforms Supported: Android, Microsoft Windows, Linux, iOS, PlayStation 3, Xbox 360, PlayStation Vita, macOS, Mac operating systems

If you’re looking for strategy Sci-Fi Games, then this is the perfect game for you to play! Well, to be honest, it’ll be a love-hate relationship, for you’ll be using the best of your abilities and then get defeated, only to come up with something even better! The notoriety of this game comes from its difficulty; yet again, it’s a chart-topper owing to this very reason. 

The tact-based gameplay makes up for a chief factor. However, the sci-fi setting and gameplay mechanics make it among the top picks for all the sci-fi junkies out there. Just when you think that you’ve made it through the hard playthrough, the arbitrary assortment of villains, aliens, and whatnot, invading in ways you perhaps couldn’t have even thought of, becomes the ultimate turning point of your play. 

3. Portal

Metacritic Rating: 90

Platforms Supported: Nintendo Switch, PlayStation 3, Xbox 360, Android, Microsoft Windows, macOS

The best of first-person shooter mechanics, coupled with the element of puzzle solving, makes it a unique pick of Sci-Fi games to add to your gaming roster. The unconventional game mechanics that continue the action sequences, paired with the tenet of solving puzzles, allow you to explore the world of Portal with an entirely new lens. 

And would you believe that these aren’t even the chief reasons or elements as to why it’s among the top Sci-Fi Games? The storytelling, subtly dark sense of humor, and quirky puzzles peppered throughout the gameplay make it a must-have. 

Unlike most games that test the finesse and challenge a player’s intellect, this one allows you room to breathe and play at your own pace while immersing yourself completely in the gameplay. In addition to this, the plotline of a human lab rat attempting to escape a space created by AI portrays the carnivalesque, humorous nature of the game. While this may be one perspective, it also alerts the user about something beyond just gameplay humor and pushes food for thought with respect to the ethics of AI. 

This subtle yet holistic sci-fi video game is essential for all gaming enthusiasts across the globe!

1. Half-Life 2

Metacritic Rating: 96

Platforms Supported: PC (Steam), Xbox 360, Xbox (Original), PS3, macOS, Linux, Android

Alien Infestation? Check! Is Gordon Freeman in action again? Check! Rescue, sci-fi futuristic story? Check! The fan-favorite franchise, Half-Life, broke records in the gaming industry, and the sequel has, till date, carried forth the legendary legacy of the game. When it comes to sci-fi, Half-Life 2 is the prototype for several modern games! 

While one may assume that the early 2000s graphics could hinder the gameplay with modern technology, as we’ve said, it’s classic for a reason! Source, i.e., the proprietary engine of Valve, the Developers, makes the gameplay graphically and play-wise smoother altogether. The grappling narrative pushes you toward the action that entails, thus providing you with the best of both worlds. If you’re looking for a classic sci-fi futuristic video game on Steam, Half-Life 2 should definitely be worth a try, for many players have been disappointed! 

Summary

These games are more than just a series of quests and button-mashing; they’re your ticket to alternate realities where you can be the hero, villain, or cat with a mission. From the depths of underwater facilities in “Soma” to the neon-lit streets prowled by felines in “Stray,” we’ve zigzagged across the cosmos to bring you the crème de la crème of sci-fi gaming. Every title is a wormhole into a universe where the impossible becomes possible, and every gameplay is a story waiting to be told with a twist of the extraordinary. So, grab your space helmet (or cat ears), dive into these sci-fi worlds, and let your imagination run wild!
