Halo 3: Combat Evolved


Halo 3: Combat Evolved is a mod for Halo 3: ODST that re-creates the Halo: Combat Evolved Multiplayer and Campaign experiences within Halo 3: ODST.

The mod is HEAVILY work in progress, bugs, issues and missing content is to be expected. I am the only person working on this mod currently and remaking all levels from Combat Evolved, polishing them, ai placement, scripting and more takes a huge amount of my time so there is bound to be issues I overlook during development. If you found any bugs or have general feedback make sure to let me know!

Because this mod utilizes the Halo 3 ODST engine, you can play through Halo: Combat Evolved's campaign with up to 4 players in online Co-Op. A few select cutscenes have also been modified to account for the increased player count.

While I wanted the mod to stay as close as possible to Combat Evolved, I eventually made the decision to introduce cut content from Combat Evolved as well as a few custom (non intrusive) encounters to spice up the campaign and give it a fresh coat of paint.

Cut content such as encounters, scripts, items and set pieces have been re-added.

How to Play
To play, simply just subscribe to the mod and wait until the download is finished. Once finished you need to launch MCC with EAC Disabled.

For Campaign you need to head over to Campaigns > Halo 3: ODST > Halo 3: Combat Evolved and select any level.

For Multiplayer you need to head over to Multiplayer > Custom Multiplayer > Halo 3: ODST > Modded Maps. Unlike Campaign, all of the workshops items you've subscribed to are shown. Halo 3: Combat Evolved maps will have "Halo 3: Combat Evolved" in the end of their descriptions.

For Firefight you need to head over to Firefight > Halo 3: ODST Custom Firefight > Modded Missions. Just like Multiplayer, all of the workshop items you've subscribed to are shown.


If you've been enjoying my work on Halo 3: Combat Evolved, consider sending me a donation on ko-fi![ko-fi.com] This project takes up a huge chunk of my time and I work on it absolutely free! Donations are optional and nothing will ever be paywalled.

The goal of this project is to remake every single Campaign and Multiplayer level from Halo: Combat Evolved, for now the list of available content is down below. Remember, this project is heavily work-in-progress and the list of available levels will continue to grow overtime.

  • The Truth & Reconciliation

  • Danger Canyon
  • Chasm 34 (Chiron TL-34)

  • Hangar A-2

Known Issues

Keyes uses Romeo's dialogue in-gameplay
There's a chance you can soft lock when Keyes is about to die right when you get a checkpoint
Projectiles have a chance to go through "4 way" hallways in The Truth & Reconciliation

Sentinels, Flood Stalkers and Flood Tanks do not spawn and can soft lock the session
Many issues with 4+ player firefight

Absolute 10/10 ! had to give an award for it. If I can have any input at all to make it even better, it would be the elites. Instead of making them 100% Halo 3 elites, I would make them the original Halo CE elites but with a Halo 3 elite skin. Aside from that, I am really looking forward to the rest of this Mod being completed ! Exactly how Halo CE anniversary should have been made back in 2011. (rather than the nonsense 343 gave us)

I want it to come out to, but the mod author is getting burned out on the project because she's basically trying to re-create the level Halo from scratch and it's exhausting. It doesn't help that the halo community is full of assholes. Plus this one particular asshole.

Please, I'm dying to play the rest of the game like this! I will donate to you! How much do you need to make this happen?

Very nice mod overall, i just think that inside the ship it should be a little brigther, but also (and this may be a problem caused by my pc) the friendly ai needs to be a little bit more active:
- outside the ship, they will only advance once i am basically at a new checkpoint;
- both inside and outside the ship they will shoot only occasionally, while also preferring to get close to the enemies in order to melee them.

How is the creator's fault that you play games with a very weak and old laptop?

Almost perfect, just one problem.... unplayable low fps

Absolutely AWESOME!!! It looks and feels so right :D
This must have taken you a lot of time but it is worth it! Genius idea to use ODST for this :)
(One minor note: the stational turrets are a bit off to the right of the crosshair. Not too dramatic- you can still see clearly where the shots land.)

Can´t wait for more levels to come out! If there is any way to support you I would love to contribute :)
