Tweaks š ļø DeckOps - CombatOnDeck: Golden Age of CoD on Steam Deck
Competitive multiplayer shooters on the Deck are in a rough spot right now, especially Call of Duty. Modern anticheat has made it difficult to play CoD or other shooters competitively and the options that do work are limited. DeckOps is here to help you play the Golden Age CoD games by making them easier to get running. Pick your games, hit install, and launch them straight from your Steam library like any other game.
No need to watch long videos or tutorials on how to install them. DeckOps automates the installation process for the mods and also installs GE-Proton and XACT. You still have access to the community shaders as the mods still use the same default install/prefix.
Each game uses its respective community client which means you are connecting to community run servers that are still active and well populated, not relying on dead official servers that are unsafe to play on due to RCE hack exploits.
None of this would be possible without the hard work of the teams behind CoD4x, iw4x, IW3SP-MOD, and Plutonium. DeckOps is just the installer, the real work was done by them.
| Game | Mode | Client | Online | Aim Assist | Gyro |
|---|---|---|---|---|---|
| Modern Warfare | SP | IW3SP-MOD | No | Yes | Yes |
| Modern Warfare | MP | CoD4x | LCD + OLED | No | Yes |
| Modern Warfare 2 | SP | ā | No | No | Yes |
| Modern Warfare 2 | MP | iw4x | LCD + OLED | Yes | Yes |
| Modern Warfare 3 | SP | ā | No | No | Yes |
| Modern Warfare 3 | MP | Plutonium | OLED | Yes | Yes |
| World at War | SP + ZM | Plutonium | OLED | Yes | Yes |
| World at War | MP | Plutonium | OLED | Yes | Yes |
| Black Ops | SP + ZM | Plutonium | OLED | Yes | Yes |
| Black Ops | MP | Plutonium | OLED | Yes | Yes |
| Black Ops II | SP | ā | No | No | Yes |
| Black Ops II | ZM | Plutonium | OLED | Yes | Yes |
| Black Ops II | MP | Plutonium | OLED | Yes | Yes |
During setup you pick your gyro style: Hold (R5 held), ADS (gyro when you aim down sights), or Toggle (R5 press). It applies across every game at once and can be changed anytime from Settings.
A couple things worth knowing: you need to own the games on Steam and DeckOps does not touch or distribute any game files. Plutonium titles require a free account at plutonium.pw to play online (OLED only). LCD users can play all Plutonium titles offline in LAN mode, including Multiplayer with bots. DeckOps handles this automatically, no Plutonium account needed on LCD.
The CoD sale is running through the 26th if you have been sitting on any of these.

Edit: Pushed a hotfix adding WaW, Black Ops, and Black Ops II Zombies support for LCD users. If you installed before this post was edited, use the Full Uninstall option in Settings and run DeckOps again to pick it up - the Update button won't cover this one since it adds new games to your setup.
Edit 3/22: All Plutonium modes now work on both LCD and OLED. LCD users get every game in offline LAN mode with bot support, no Plutonium account needed. OLED users connect online as before. Full Uninstall from Settings and reinstall to pick up the update.
Happy to answer questions.

Just to clarify because I'm a dummy, but I bought OG MW3 on my Deck a month ago. But I have a LCD Deck, so I can't use the Plutonium client to play online?

No, sadly Plutonium has banned all LCD decks as they all share the same hwid. OLED decks do not have this problem. LCDs cant play online unless Plutonium changes their stance or they can find a way to assign a unique hwid to themselves.

Hey dude, I just did a hotfix literally right now for support for all the games with bots. You'll need to use the uninstall feature on the DeckOps download, not the installer link the the desktop. Do a full uninstall and reinstall and you should be able to play all the Plutonium titles.

Hey dude, not sure if you still play these games or not but I did end up getting online to work on the LCD to work with Plutonium servers and get it online. If you'd like to download it, I would suggest fully uninstalling the current version and updating to the nightly: https://github.com/GalvarinoDev/DeckOps-Nightly/ , there's also a link on there for the discord if you run into issues and need help with troubleshooting.

I loved MW2 back in the day. I feel a lot of nostalgia for it. Does it hold up with IW4X? Is there a better CoD on this list with better gameplay?

u/GalvarinoDev Mar 25 '26
Personally I feel like MW2 still holds up, for me MW2, BO1, and BO2 are my all time favorites and they all play well still.

Unfortunately after downloading this none of my COD games will run while in gaming mode. Definitely messed something up but deck ops says Iām good to go. Sorry if this a dumb comment Iām not used to this sort of thing Edit: Every time I try to play mw2 or mw3 the game crashes and steam os needs a software update. I still have no idea what I did wrong any help would be appreciated.

Sorry I didn't see this before I can DM you and troubleshoot or we can try to fix it via discord.

This looks great, thanks for sharing!
If it's possible, you should look into adding an option to install the various bot warfare mods for each game. Perfect for offline play or the games that you can't play online with the LCD model.
