One of those things that define multiplayer games is the fact that they are continually changing. Between patches, fixes, and seasonal contents, games will change, for better or for worse. Due to that reason, there are so many games that take different forms through patches, which make them utterly different from the games' original style. And those changes, are the reason why players can keep playing one title for so long, and how those games continue to stay on the market well after release.

Today, let's take a look at five of those "keep on changing" multiplayer games, which underwent meaningful changes in 2018, along with the reason why those changes bring forth great gaming experiences to gamers as a whole. In no particular order, the list below is five best evolving multiplayer games of 2018.

Tom Clancy's Rainbow Six Siege

Rainbow Six Siege Year 4 Pass Hero

Ubisoft has a big ambition: to keep on sustaining their tactical FPS title Rainbow Six: Siege over the years, and their efforts to do so clearly paid off. Following a mild launch in 2015, Ubisoft keeps serving the player base with a lot of patches and significant content drops. Those efforts from Ubisoft has helped elevate the game's great foundation. In 2018 alone, Rainbow Six Siege brought to players four major content updates: Chimera, Para Bellum, Grim Sky, and Wind Bastion. Along with these updates are eight operators, two new maps, significant map changes, and numerous tweaks to how existing equipment and mechanics. With their efforts, Ubisoft has been able to maintain a delicate balance even when introducing additional operators who bring new abilities and tactics to the game.

Because of those above reasons, no two matches of Rainbow Six: Siege are the same with environmental destruction, countless tactical possibilities, and unique in-match situations. And as of today, Siege continues to thrive by supporting its community, being transparent with its roadmap, and delivering a distinct, deep competitive shooter experience that "keeps on giving."

Fortnite: Battle Royale

If you had to point to the biggest story in all of the games in 2018, most people would agree with the same answer: "Fortnite." The free-to-play battle royale game has become a cultural phenomenon with the largest active player base in all of the games. It's safe to say that Fortnite's success had propelled Epic Games to new heights of success.

The difference of Fortnite, when compared to a whole bunch of other Battle Royale games on the market, is the building elements from the original Save The World mode. With this mechanic, Fortnite leads players to so many tactical possibilities and unpredictable combat scenarios.

Fn12

However, its success in 2018 undoubtedly comes from the impactful changes with each new season. The game has been running on seasons (its currently on season seven), and in this year alone, we've seen significant changes to the map, new weapons, different modes, inventive challenges, and collaboration events (like the limited time event that let you play as Marvel villain Thanos and use the Infinity Gauntlet to tear up opponents).

When compared to its direct competitor PUBG, Fortnite still only has one map, but large swaths of it are hardly recognizable from its original layout as they've been reworked to fit a loose narrative that comes with each season. Sometimes, rifts appeared on the field and teleported players across the map, or a mysterious meteor came down to obliterate a whole town. Fortnite has a lot of changes already, yet still keeps on going and exploring new possibilities to improve players' experiences.

Overwatch

Overwatch is a game aims to be a competitive shooting game, and thanks to Blizzard's pedigree and history of finely crafting multiplayer experiences, the game keeps on delivering. In 2018, Overwatch continued the tradition of seasonal festivities with new character skins, thematic changes to its presentation, and occasional modes to fit the event.

Ow Main Screen

For example, the annual Summer Games took place in Overwatch with its vaguely-Olympic theme and included new cosmetics and the return of Lucio Ball, the 3-on-3 Rocket League-esque game mode. Lunar New Year event brought forth a bunch of creative skins, and the Winter Wonderland event this month is undoubtedly the same.

Of course, new heroes are always changing the game; with 2018 brings Brigitte, Wrecking Ball, and Ashe to the table. All are entirely new characters, with their backstories and unique abilities. Between its updates, additional content, and competitive spirit, Overwatch isn't slowing down any time soon. Maybe, that's the reason why the game is still the best Esports game at this year's The Game Awards.

Warframe

Much different from those titles above, Warframe is a prime example of how a game can completely transform itself into something more significant over time. The free-to-play cooperative third-person shooter had two expansions in 2018, named "The Sacrifice" and "Fortuna." These updates delivered a slew of contents and reworked several elements of the core game. However, between the two updates, Fortuna brought more significant changes to the game by introducing an entirely new open-world planet to explore with a neon-lit city below its snowy surface.

Along with that, movement within the game also changed with the K-Drive hoverboard - which allows players to customize to their liking. For the more quiet moments, Fortuna has fishing and mining, and the new hunting activity. It's Warframe's most significant expansion yet that's on PC and will soon be available on PS4 and Xbox One.

Pokémon Go

Pokémon Go is a unique experience that extends beyond the game itself. It's very much that mobile AR game that got you up and out in the real world to catch Pokémon scattered throughout your city, but continual support has kept it alive and more active than ever before. This year, the game brought to the table Gen 3 Pokémon, along with the plan to roll out Gen 4 Pokémon. There's also a weather system that accounts for the actual conditions in your environment; there are some status effects and boosts to certain types depending on the weather. As a plus, at the end of 2018, the game will finally open the much-awaited PVP system.

This year introduced to the game Community Days - which happen monthly and offered an exclusive move for a particular Pokémon that spawns at a higher rate, along with a shiny version of the Pokemon to catch.
