List of Best Multiplayer Games on Steam in 2025

Some are all about fast fights, others are full of deep strategies and crazy stories. No matter what you like, these Steam multiplayer games have something waiting for you. Now let’s start the countdown from number 10!

10. PUBG: Battlegrounds

Dozens of players enter a huge match in PUBG: Battlegrounds with one clear goal – to be the last survivor. You step into the role of a fighter who must rely on weapons, armor, and vehicles found across the map to outlast every rival. The game throws everyone into a shrinking safe zone, so battles grow tighter with every passing minute. Gunfights are tactical, with single shots or bursts deciding who controls the ground. Vehicles turn into both transport and weapons, letting you crash into enemies or escape ambushes. Every match plays differently since no one begins with the same gear or position. PUBG stands as one of the best multiplayer games on Steam because the tension of surviving until the very end never fades.

9. REMATCH

For the fans of competitive football games, REMATCH offers a different perspective by giving you control of just one athlete in a 5v5 match played from a third-person view. Every match puts you right on the pitch, handling dribbles, tackles, and shots with precision while your teammates cover their own roles. There are no fouls, offsides, or breaks, so everything depends on raw skill and how smartly you position yourself during play. In this setup, decisions matter, from choosing when to pass to taking the perfect shot at goal. Overall, REMATCH is one of the best multiplayer games on Steam, especially when you’re looking for a fresh way to enjoy high-energy matches with friends.

8. Dead by Daylight

Four survivors are trapped in a deadly trial while a powerful killer hunts them down in Dead by Daylight. You either step into the role of one of the survivors, working together to repair generators and open the exit gates, or take control of the killer whose job is to stop the escape. Survivors win by staying quiet, fixing machines, and slipping past danger, while killers rely on special powers to track, chase, and catch their prey. Matches turn into a mind game of hiding, running, and predicting what the enemy will do next. Dead by Daylight is counted among the best multiplayer games on Steam because of its mix of horror, strategy, and heart-racing moments between friends.

7. Ultimate Chicken Horse

Ultimate Chicken Horse is a party platformer built around chaos and creativity. You control quirky animals racing across short obstacle courses while trying to reach the finish. The catch is that players design the course themselves as the match goes on. At the start of each round, everyone chooses an item like a trap, platform, or gadget and places it onto the level. Once the round begins, all animals run through the same course filled with hazards created by the group. The goal is simple: finish the level while your friends fail. Success earns points, failure brings laughs, and new rounds keep changing the challenge. It’s pure fun, and one of the best multiplayer Steam games for silly competition with friends.

6. Titanfall 2

Fast action takes over in Titanfall 2 as you step into the boots of a pilot trained to fight with speed and precision. The game drops you into online battles where you sprint on walls, slide under cover, and use futuristic weapons to outplay enemies. Matches are not just about pilots though, since you can call in massive Titans during fights. Titans are giant armored machines that carry heavy guns and can crush smaller targets. Combat flows between fast pilot fights and powerful Titan battles, creating a constant shift in pace. So, if you’re into first person shooters, it is one of the best multiplayer games on Steam to consider because no other shooter blends human skill with mech warfare in such a smooth way.

5. R.E.P.O.

R.E.P.O. is a co-op extraction game where you step into the role of a recovery crew sent into strange buildings to collect valuables while avoiding unpredictable monsters. Up to six people can play together, or you can try solo runs if you want more challenge. Each session revolves around spotting loot, using a gravity tool to lift it, and careful steer toward a central platform that counts the value of everything delivered. Items can break if knocked into walls or dropped too hard, which often turns attempts into chaotic moments around you. In addition to this, strange monsters roam the area during every run, and you must balance loot collection with survival.

4. Schedule I

In Schedule I, you run a first-person management sim where the aim is to grow a drug empire from nothing into a large operation. You start with no cash and no product, then move into producing different substances, each tied to its own recipe and method. The game pushes you to manage production carefully, discover new variants, and maintain steady supply. Distribution can be handled directly or by hiring others to reach customers across Hyland Point. What begins small can turn into a fully automated chain that operates like a business machine. Also, co-op multiplayer lets friends join in and manage the empire together.

3. Grounded 2

Grounded built its name by shrinking players into a backyard where survival meant crafting tools and fighting giant bugs. The sequel moves into Brookhollow Park and introduces bigger dangers with even more ways to play. New insect buggies change everything since you can hatch, raise, and ride them during your journey. These creatures fight beside you, carry supplies, and even help in battles against tougher enemies. And co-op remains a highlight since every task feels more fun with other players. If you are looking for open world survival games on Steam to play with friends, Grounded 2 is a must-try.

2. Marvel Rivals

What could be more exciting than stepping into the shoes of your favorite Marvel superhero and fighting in team battles? Marvel Rivals brings heroes and villains together in six-versus-six matches, where every character has unique powers. You pick a hero, join a squad, and fight to control objectives while facing another team of superheroes. The action never slows down with flashy moves and constant back-and-forth fights keeping every round intense. It’s no surprise Marvel Rivals is one of the best multiplayer games on Steam right now.

1. PEAK

The final game on our list of 2025’s best multiplayer games on Steam is PEAK, a co-op climbing adventure about a group of stranded scouts. The only chance of rescue lies at the top of a massive mountain sitting at the center of the island. Every step is about careful climbing, smart stamina use, and trusting your group to pull you through tough spots. Gameplay is simple to understand yet always tense. Stamina drains as you climb, so resting or eating food is needed to stay alive. Items like ropes and spikes give support on dangerous sections, while communication helps warn friends or plan moves.
