Halodoom is a fangame that pays tribute to the Halo universe and seeks to push the Doom Engine to its limits! 

While utilizing the source port Zandronum, Halodoom offers a totally unique and standalone modern Halo experience within the classic engine that originally spawned the first person shooter genre!  

Halodoom was a solo project I first started when I was 15 years old and had no idea how to go about making it happen. Initially brought about by a desire to play Halo on an iPod Mini after learning it could run Doom, the project soon snowballed into something that I would carry with me for half of my life, and would set me on a path of game development that I am still on today.  It has seen several iterations in the past, and gone by many names, a comfort project I could pick away at whenever I felt the urge. Now, 15 years later, it's time to finally do justice to the first game I ever made. It's time to finish this fight!


16 Weapons and 4 Grenade Types and Classic Powerups

Halodoom's Weapons Sandbox includes : Assault Rifle, Battle Rifle, Magnum, Sniper, Rocket Launcher, Shotgun, Spiker Rifle, Mauler, Chainsaw, Plasma Pistol, Plasma Rifle, Carbine, Needler, Fuel Rod Cannon, Energy Sword, Beam Rifle, Frag Grenades, Plasma Grenades, Spike Grenades and Firebomb Grenades. You will also occasionally find an Overshield or Active Camo!

8 Armor Coatings With Adjustable Primary Color

Customize your Mark VI Armor set with 8 different coatings, combined with a slider system for primary color, you have a myriad of different aesthetic options!

Flood and Covenant Firefight With 8 Hidden Unlockable Skulls

Fight against waves of either Covenant (On the map Terminus) or Flood (On Flood Gulch). Firefight offers a range of difficulties from Easy to Mythic, as well as the option to Save/Load your game. Once you've found and unlocked Skull modifiers hidden within the various maps, you can enable them in this mode to yield some pretty absurd results!

72 Possible Game Mode Combinations!

Halodoom offers a handful of familiar game types including Slayer, Oddball, King of the Hill, Juggernaut,  Infection and SWAT (With more on the way in a future update) . Coupled with 12 unique weapon start templates, you'll never run out of variations to try out! You can also play either Free for All or as a Team!

Interactive Main Menu Map

Halodoom contains an interactive main menu with visual aids to better help you get started. Custom views will pop up for map selection, player customization and bot selection.

15 Custom Bots 

Engage in combat with these highly customized bots. If you've ever played Doom with bots you'll know they can be a bit... simplistic. These bots have custom behavior which allows them to better utilize the maps and game types.

13 Multiplayer Maps

Test your skills against bots on 13 multiplayer maps which contain classic remakes of both Halo and Doom staples, as well as a healthy dose of original creations. (Online multiplayer with custom server browser coming soon in a future update!)

Lockup - Remake of the classic Halo 2 map Lockout

Submerged - A carousel of carnage
Rebellion - Medium sized arena map with a great view of High Charity!

Terminus - A remake of Halo 2 's Terminal
Schism - A cyclical midsized arena map reminiscent of several Halo staples.

how do i start a game

(2 edits) (+2)(-4)

how to make halodoom better and funnier

1. pls add a campaign.

2. pls add a Search and Destroy gamemode ~ Search and Destroy: Teams have to take turns either planting the bomb to destroy an objective or defending the objective.

3.  pls add driveable vehicles like hoverboards maybe add jetpacks.

4.  pls allow us to make custom maps, and custom weapons.

if you add these things halodoom will be ranked #1 on my top favorite games list (halodoom's number #3)


Absolutely no, you wanna make halo like call of duty! Go play more HALO  and less cod


k, thx for the advice 👍


Tf do you mean? Campaign, drivable vehicles, and custom maps have been in the Halo franchise since the CE. If anything, adding that stuff would make it MORE like Halo. Having a S&D game mode could be pretty interesting given Halo's game mechanics. Maybe don't talk about things you know nothing about.

"Maybe don't talk about things you know nothing about."

calm down, i was just making some suggestions 

no need to get mad about it also darkhero67 asked for story mode

Campaign (or Story) Mode is useful as a term to distinguish it from other modes of play that a game might offer.



I wasn't talking to you. I was talking to blacks7orm2025. I agree with what you were saying.

oh sorry i didn't really read your comment. i only read the last sentence.

Well if the developers can only make this game available on Android it will be the best for me

This is one of the best games I have ever played. If there is a multiplayer update or even just a LAN update this would be top 5 game for me of all time. You mentioned you are in game development. I don't see any of your other games on itch, what are they? 

This is awesome! One question tho...

Do bots also work for coop?. . .

I will be disappointed if not



ive never downloaded a game how do a start it


any plans for a story mode


GZDoom port when ?

I love this dude. How the hell did you keep this gem of a project a secret!?! You, my friend, are a real one. True masterpiece. Keep it up for the sake of humanity!

This is legit OG Halo gameplay! So Awesome bro!

(1 edit)

This is marvelous, wow!

Thank you for this. Its been fun. I heard you were supposedly going to release a standalone version of the enemies in this mod. Is this true, and if so, any idea when it will come out? Thank you in advance.

Hello... I wanted to say that this game is fantastic.. I play it on my mobile device with the Delta touch application.. I've been playing it for days without stopping, the bots work wonderfully, it has all the details of a halo... Thank you very much for creating it..


when you launch if you click zandorum.exe it will take you to a unfinished game called free doom

(1 edit) (+2)

There are launch instructions on this page, but basically you have to launch Halodoom through its own custom launcher, via Halodoom.exe or the shortcut to it in the root of the folder.

Zandronum.exe will just run Zandronum with the included free version of Doom haha.


i already know how too launch halodoom i like the game i just found that free doom was on there


Unfortunately its not very well optimized. I can't even play it it lags so bad, even with all the settings lowered. Looks really badass though on the video!

I'm sorry to hear you're having issues, would you mind sharing your specs?

8 gigs ram, AMD Radeon Vega 8 GPU, AMD Ryzen 5 345OU 4 core CPU 2.10 GHz

Similar issues here with  i7-10750H and GTX 2070.
