If the main reason you enjoyed the Halo series was solely for the multiplayer online experience of fighting in an arena FPS, then Tribes: Ascend would be your best bet if you want to have that same kind of experience. With the initial Tribes game being inspired by the multi-player maps seen in Halo 2, it’s no wonder that many fans turned to this franchise and stuck with it for quite some time. With a large community, games such as Capture the Flag, and similar combat mechanics that also involving jetpacks, vehicles, and much more, Tribes: Ascend is at the very least worth checking out.

If Halo was the defining sci-fi FPS game for the Xbox, then Killzone was the PlayStation’s defining sci-fi FPS game. Killzone is similar to Halo not only in terms of multi-player gameplay, such as holding multiple weapons and the various competitions held over a variety of different maps, but the story as well, with many comparisons between the Helghast and the Flood as well as the Interplanetary Strategic Alliance (ISA) and the UNSCDF. The Killzone franchise also has a long timeline, with the first game coming out in 2004 and the most recent iteration, Killzone Shadow Fall, being released in 2013 for the PS4. Overall, if you enjoyed both the campaign as well as the multi-player mode for Halo but prefer a game for the PlayStation console as opposed to the Xbox, Killzone is that game.

Another great PlayStation FPS, Resistance’s campaign mode focuses on Sergeant Nathan Hale as he, along with other resistance forces, try to defeat a mysterious alien species known as the Chimera, who has already taken over the rest of Europe and is now infiltrating the U.K. Like Killzone (and therefore Halo), Resistance has similar fighting mechanics, similar multi-player games such as Capture the Flag, Assault, and Free for All, and similar maps despite being off of certain locations in England. Resistance also can be compared to Halo in terms of both conventional weapons as well as futuristic weapons being used, resulting in some interesting matchups. While there aren’t that many games in the Resistance franchise, the feel of the game in addition to its fighting mechanics definitely bring about a comparison to Halo in both the campaign fights in addition to the multi-player fights.

Bioshock Infinite’s biggest comparison to Halo is more so in regards to the story as opposed to gameplay. In contrast to Halo’s futuristic outer space sci-fi setting, Bioshock’s setting is more tied to the survival horror genre combined with a biopunk feel. In addition, while it is also a FPS, Bioshock Infinite incorporates superpowers in addition to some RPG elements as opposed to Halo’s more objective-based approach through the campaign. There is also no online multi-player dynamic to Bioshock: Infinite as well, as the main focus is on the campaign. Therefore, if the Halo story in terms of exploring a whole new environment in order to perform a rescue operation as well as uncover a mystery appealed to you, then Bioshock: Infinite will definitely satisfy that and leave you wanting more.

A reboot of the iconic franchise and the first installment since Doom 3 was released in 2004, Doom was one of the few successful multi-player FPS games out before Halo, and this latest iteration brings a return to that kind of game while improving upon it at the same time. Although there is a lot more graphic violence in Doom as well as a difference in terms of the type of enemies being fought, Doom does share with Halo an impressive arsenal of weapons to use in addition to a new take on the combat system to utilize these weapons to their best potential. Doom also has similarities with both its multi-player games (team death match and king of the hill with a moving hill for example) as well as a “level-creation tool” for players to construct their own maps as they see fit. Not to mention the unique soundtrack that adds to the unsettling atmosphere. If you particularly enjoyed the violence of the Halo series, particularly in the earlier Halo games, then Doom should have no problem entertaining you.

One of the things that the later Halo games were able to capitalize on very well were the graphics; Halo 5 in particular showcased some characters so well that they almost appeared real. This is also a standout point for Crysis, a standard sci-fi FPS shooter game where the protagonists use nanosuits to give them enhanced strength, speed, and even durability to combat other soldiers and aliens. While the story is not as sophisticated as the story in Halo, the later installments were able to improve upon this aspect, which is why both Crysis 2 and 3 are considered to be more popular than the original. If you enjoyed Halo for the graphics that it provided for its unique sci-fi setting, then Crysis would be the game to start with to experience that type of visual.
