Infantry Online

Massive multiplayer online isometric shooter.

About FreeInfantry

FreeInfantry pits you against hundreds of players in real-time, fast paced tactical combat. Use momentum to your advantage and to your enemies detriment as your bullets and explosive shrapnel ricochet using Infantry's Newtonian physics model. Plan your attack from the shadows and ambush your enemy thanks to Infantry's real-time Fog of War visibility model.

With a vast collection of player-made game arenas, enter the bloodbath in Skirmish and Frontlines Zones, the dynamic and base defense-oriented Capture The Flag Zone, and dominate the space in Fleet Zone. Survive with your team against the neverending tide of computer-controlled AI in Zombie Zone, or play against the swarm of player aliens in Bug Hunt. The choice is yours.

What's New

FreeInfantry is on Steam

Apr 2024

Brief announcement for a heroic effort from the development team and everyone involved.

We have successfully launched FreeInfantry on Steam. Click here to view the store page and download the game.

Huge thank you to everyone who has participated in making sure we have a smooth launch, and to all the players who took the time to play test the zone and keyboard/mouse changes we have been working through. We have handed out close to 100 beta test keys along the way.

We will be phasing out the non-Steam Windows launcher from the website. If you already have Infantry, it will continue working without any issues going forward. For everyone else, Steam version is highly recommended because it will have all updates and fixes going forward.

Get the latest version and we'll see you in-game!

USL Season 20

The 20th season of the Unified Skirmish League on FreeInfantry is starting up. Read on for details on how to participate.

If you have not already registered, please visit the official https://uslzone.com site, create an account and mark yourself as a Free Agent. This allows squad leads to invite you to the league to play.

Many thanks to Champion (Chris) for running USLZone. All inquiries regarding your USLZone account should go to him. As always, feel free to drop into our Discord Chat for any questions around FreeInfantry or USLZone.

We'll see you in-game and in the league!

CTF: Remastered

May 2023

Directly from Dolche and Morning:

CTFR is currently in early stages. We've already done our armor overhaul, and we're currently looking at giving players more choices than just a 606, RPG and RG. We'd like to make player preference be more than just a handicap, and more of a choice for individual playstyles. The weapons may take some time to be balanced properly, but we need testers and feedback in order to properly balance things, so please bear with us while we make the changes. Our first priority is to make every weapon something more than just "606, but worse" or "606 but MUCH worse". Please feel free to leave us some feedback in the discord.

Get in there!

HTTPS Launcher Upgrade

February 2023

We are nearing completion of our latest round of security upgrades, and are moving to HTTPS for the website as well as the launcher.

Many thanks to our community member Spiff for updating the launcher/installer to support HTTPS downloads.

The new launcher is available to download right now. Please note that in the coming weeks, we will be decommissioning the old launcher and it will no longer work with the HTTPS upgrades that we have done, so make sure you download the latest launcher ASAP.

Download the latest installer here!

Return to Eol

November 2022

The crater has been found. Can you be the one to destroy your opponents and secure it?

Thanks to our zone developer Caesar, we've resurfaced Eol and are actively working on updating it, maintaining it, and promoting it. If you are a die-hard fan, you will not want to miss out. Eol: Reforged is quickly becoming one of our most popular zones.

Eol: Reforged
Join the Collective Military and Titan Militia as they battle the aliens (and eachother) on Old Heinrich's Point. Compete in KOTH and CTF action and kill aliens and pirates for bounty.

Eol: Reforged features some of the more highly evolved gameplay mechanics of Infantry, and we are happy to be hosting once more.

Get the game and get in there!

New Installer, Higher F.P.S.

March 2022

With the recent hard work of our community member Spiff, we are excited to announce the release of a new installer that comes packaged with the cnc-ddraw library for improved graphics and rendering.

FreeInfantry now runs in fullscreen or windowed mode with higher F.P.S. and requires no compatibility overrides for modern machines!

Also, with the added scripts to easily install FreeInfantry on Linux, we now have feature parity with the 3 major PC platforms (Windows/Mac/GNULinux). One of our highest goals is to reach a wider audience. This was an important step toward completing that goal.

Check out the download page here, to grab the new installers.

SUT Evolved

February 2022

Brought to you by our long-time zone developer and core contributor HellSpawn (Josh), this zone puts an Infantry spin on the Halo series.

SUT Evolved combines multiple Objective- and TDM-based gamemodes (votable on round-end by players) and contains a dynamic respawn and weapon spawn systems. Be warned - addictive arcade zone.

Check out the gameplay preview video here, recorded by our Community Manager Cadenza.

Happy New Year

January 2022

Another great year of FreeInfantry. Lots of new development and lots of new faces.

If it's your first time here, and you can't believe Infantry is still up and running, hop into the Discord Chat and we'll see you in game!

February 2021

Courtesy of our community member Spiff, we are excited to announce the release of a macOS-based launcher. This allows you to run Infantry on macOS without having to use a virtual machine.

Eol: Pioneer Station Launches

June 2020

Brought to you by our zone developer Mode, this new zone combines classic Eol mechanics and gameplay with FreeInfantry's AI bot capabilities in a Battle Royale format.

Infilitrate enemy AI bases and battle roaming scavengers as the playable map area shrinks around you and zeroes in on a blood bath between you, other players, and hordes of tactical bots.

Please note that the zone is under active development. You may encounter glitches and bugs that we are in the process of fixing.

Recent CTF Updates

May 2020

The following list of changes were conducted by our zone developer Axidus.

  • Dynamic portal system allows for fast warping to enemy/home.


  • Brown base and outside portions surrounding brown base are playable.
  • Dynamic portal system allows for fast warping to enemy/home.
  • Private teams enabled (current team size: 7).

Surface & Space Combat

Every zone in FreeInfantry is player-made, using the development tools available to you.

Io's Landing

Io's Landing

Side-scrolling shooting mania, Infantry style!

Fight through a gauntlet of AI soldiers and mechs as you dash through buildings and corridors, holding and capturing positions along the way.

Io's Landing utilizes a smart portal system that always drops you near the front line of battle, and the difficulty of the zone is scaled with the number of players.

This cooperative RPG zone is full of specialty classes, shop items, upgrades and plenty of warzone looting.

Io's Landing offers solo and cooperative multiplayer gameplay.

Twin Peaks

Modern Twin Peaks

Experience a cornerstone of Infantry-based gameplay in this highly tactical, base-defense driven zone.

The war between the Titan Militia and Collective Military wages on in this classic Infantry zone revamped on a compact map that includes enemy warps to keep the gameplay constant.

Offering a competitive armory of weapons, items, and the ability to build defensive and offensive structures, CTF is one of the oldest and highly rated running zones in Infantry.

CTF is recommended for players who are seeking the thrill of the toughest combat scenarios in FreeInfantry.

Bug Hunt: Extermination

Bug Hunt: Extermination

Put down the Raid can and pick up your raid gear because we've got bugs...big bugs.

Embark on the rescue mission to research facility, Saturnalia and save the six scientists from an experiment gone awry.

Bug Hunt: Extermination has you playing cooperatively, as the humans, against the AI-powered alien invaders -- the bugs!

Fleet StationPass SOE


Two space colonies battle for territory in one of FreeInfantry's biggest zones. Board massive, multi-player ships and engage in an all-out territory war in Fleet.

Harvest and steal enemy supplies, build defense structures and frigates, and assail the enemy mothership, Fleet offers one of the most dynamic space game scenarios to date.

...and many other zones.

FreeInfantry is proud to host the Unified Skirmish League and the CTF Public League.

League matches are held during weekends. We recommend new players to spectate league matches to get a better understanding of the high-level gameplay that FreeInfantry offers.

Frequently Asked Questions

Can I play the game today?

Absolutely. FreeInfantry has been up and running for over a decade. Download the game launcher and jump in.

A large portion of players usually start to log on around 8pm EST, if not earlier. Recurring events such as Twin Peaks Tuesdays (TPT) are organized by our community managers in the Discord Channel.

I forgot my username / password

Note that our account system is not connected to any older account databases. If you had an account with them, you will need to register with FreeInfantry separately. We do not guarantee that your previous SOE aliases will still be available.

If you have an account with FreeInfantry already, you can perform a password reset by clicking on the Forgot Password button using the Game Launcher. Alternatively, you can speak to one of our admins in the Discord Channel for account-related inquiries.

I can't connect to the server / can't register an account (server error)

Make sure that you have port 1010 open on both your Windows Firewall as well as your router/modem.

Map editor crashes / won't render properly

Run Windows XP inside of a VM. We highly recommend you use Microsoft Virtual PC along with Windows XP Mode. Other virtualization software (VMWare, Virtual Box) work as well.

Otherwise, we recommend that all tools be run in Compatibility Mode with 16-bit Color Mode checked. Experiment with settings until you find a combination that works for your system.

How can I play on macOS?

You can download our macOS-based launcher by clicking here.

Alternatively, we recommend installing Windows via the Boot Camp software that’s pre-installed with macOS. Boot Camp simply let's you switch between macOS and Windows without effecting the current OS install. This has been tested by many of our players.

Please follow the instructions here: https://support.apple.com/en-gb/boot-camp

Other options exist such as Geforce NOW and Parallels but have not been fully tested.
