The best action games for PC can be found in this article. Most PC games are controller-compatible , so playing with just a keyboard and mouse won't be a problem; you won't have any limitations.
Although Steam is the most widely used platform and offers a large number of games, not all the titles included in this article are available on Valve's platform. Some of these games are only available on the Epic Games Store, the creator of Fortnite.
Counter-Strike: Global Offensive

With over 20 years on the market, CS:GO was one of the first team-based first-person shooter games that popularized this genre, a genre that has subsequently been implemented in other titles such as Valorant and Tom Clancy's Rainbow Six Siege , adding abilities to the characters.
Tom Clancy's Rainbow Six Siege is available for free download on Steam via the following link.
Valorant

The quick summary of Valorant is that a CS: GO where the characters have powers that can settle the battle of one side or the other. Valorante is a 5v5 tactical first person team shooter.
Valorant is available for free download on the Epic Games Store
Tom Clancy's Rainbox Six Siege

In Clancy's Rainbox Six we must master the art of destruction and use of tactical devices working as a team. Enter intense, highly lethal close-range combat, with tactical decisions, team play, and explosive action throughout.
All the action takes place in the first person. We have dozens of agents to choose from, each specializing in certain weapons and tactics.
Smash walls to open up new lines of fire. Break ceilings and floors to create new access points. Use every weapon and gadget in your arsenal to locate, manipulate, and destroy your enemies and the scenery around them.
Tom Clancy's Rainbox Six Siege is available on Steam for 19,99 euros through the following link.
Apex Legends

If you like first person games, you should try Apex Legends. Apex Legends is a first-person battle royale game where we have a wide variety of people with different abilities at our disposal.
It incorporates a series of mechanics that have subsequently been adapted by other battle royales such as Fortnite, Warzone and PUBG.
Every new season, a new character is introduced. It is available for free download on Steam through the following link.
PUBG BATTLEGROUNDS

PUBG was the first battle royale title to popularize this genre, although it was not the first. That honor falls to another title that currently has hardly any users.
Unlike other shooting titles, PUBG allows us to play in both first and third person, in independent modes. This title is the most realistic of all games of this type, since it is not possible to revive companions (except on the Taego map).
This title has a wide variety of maps (8 in total) that rotate every month
Also, the time-to-kill is quite low. With an AKM, you can kill two enemies with one magazine and still have bullets to spare. Being the most realistic of all, not only is it the most difficult (it doesn't tell you where you're being shot from) but also the recoil patterns of the weapons are not easy to control.
You can download PUBG for free through Steam by clicking on the following link.
Fortnite

In early 2022, Epic Games introduced a new game mode in Fortnite, completely forgetting about building. Since then, many users have now given this third-person shooter a chance.
Build mode is also available if you'd like to give it a try. Fortnite is available to download completely free of charge exclusively from the Epic Games Store.
Sifu

This title shows us the story of a young kung-fu apprentice who is looking for the murderers of his relative to take revenge. However, he has no allies to support him in his search for him, forcing himself to face countless enemies solely with his mastery of kung fu.
In your quest, you'll explore hidden corners of the city, gang-ridden suburbs… and face a multitude of enemies blocking your path. Sifu is available on the Epic Games Store for €39,99.
Destiny 2

Destiny 2 mixes first person shooter in an action adventure that will take us to an inhospitable planet that we must explore while fighting against the creatures that inhabit it.
This title is available for download completely free of charge on Stem through the following link.
Rocket League

Rocket League is a veteran game that combines soccer with cars. This title hit the market in 2015 and in 2019 it was acquired by Epic Games, making it free in the same style as Forrnite.
This title, being owned by Epic Games, is only available for free on their online store through the following link.
Brawlhalla

In Brawlhalla, the greatest warriors in history face off to prove who is the best in an epic battle of strength and skill, peppered with powerful weapons and gadgets. Every weapon you pick up will change your style of play.

How to download games from Epic Games and Steam
Before downloading a game from Steam and the Epic Games Store, we need to open an account, which will be associated with all the games we buy.
In addition, we must download the corresponding installer. This application is nothing more than a launcher for the games available on both platforms.
The Epic Games installer is available via this link , while the Steam installer can be downloaded from here.
Once downloaded, both applications will prompt you to create a user account if you don't already have one. Once you've created an account, you can start downloading the games you want, limited only by the available hard drive space.
