FIREARMS OVERHAUL is a modification for Deus Ex that replaces the game's firearms with unique redesigns that stay faithful to the original concepts. The mod also introduces realistic iron sights and the aim-down-the-sight (ADS) mechanic for all firearms, adding another layer of complexity to combat. If you are interested in the mod, whether as a player or developer, and want to assist in the implementation of new game mechanics or weapon designs, feel free to leave a comment or private message. We could always use more contributors.

Launch Announcement


Firearms Overhaul is a project that revitalizes the shooting aspect of combat in Deus Ex by introducing newer higher-resolution models, textures and animations to the game's weaponry, keeping the designs as close to the original as possible without compromising quality. The project also introduces iron sights to the game and the aim-down-the-sight (ADS) mechanic and an expanded modification system. The concept behind the mod began nearly 10 years ago in 2008 as a simple multiplayer mod, but expanded only in recent years after being lost in development hell.


* Provide high quality and aesthetic replacements for the game's firearms
* Ensure faithfulness to the original designs
* Fully functional aim-down-the-sight (ADS) mechanic that utilizes iron sights
* Expanded modification system with more visual customization
* Addition of immersive elements such as a separate animation for the under-barrel grenade launcher
* Act as a non-intrusive standalone mod fully compatible with other Deus Ex mods


The scope of the mod is replacing the game's original six (6) firearms:
the Assault Rifle,
the Sniper Rifle,
the Assault Shotgun,
the Sawed-off Shotgun,
the Pistol and the Stealth Pistol.

All of the replacement meshes will have usable iron sights, improved and modernized animations, visual modifications that appear on the mesh itself such as an extended magazine or laser attachment, and many more elements that are being planned to improve immersion.


Currently the scope of the project is limited to the firearms of Deus Ex and not the heavy weapons or low-tech weapons such as the mini-crossbow. However, addons that will include these replacements for the mod are planned to be released in the future.


The mod is in Pre-Alpha. We have completed most of the basic modeling, skinning, animating and importing of all weapons except the Pistol. These are still considered Works-in-Progress (WIPs) and are highly subject to change and constant retouching. Design concepts may be updated or polished constantly. A rudimentary iron sight system has been implemented successfully.


If you are interested in helping with the mod, whether as a player or a developer, please send a message or comment indicating what you would like to help with. We are welcoming people with all talents and any amount of time to invest in this project, but we could especially use coders and programmers to assist with basic implementation of the mod and its mechanics into the vanilla game. Modelers, texture artists, animators and sound artists are of course always welcome. In addition, if you have any design ideas you'd like to see implemented within the mod, please also contact us.


I'm glad these weapons may finally see the light of day. Still a huge improvement. Some of them seem slightly overdesigned compared to what I had seen before (speaking of which, I hope the pistol concept hasn't changed too much), but I suppose that's true of the vanilla weapons already, and you've done a great job staying faithful to that style. Mostly I just hope the details come across appropriately in game. Iron sights are a nice touch for sure.

Wow nice, I hope to see my plasma rifle in the future.
Though I think I should create some models for it, not only as a replacement for the current DX arsenal, but also expanding a bit.
I would like a proper plasma pistol for the PS20 (and then have more ammo types based on the plasma delivery)

Always nice to see another modder patching up old gems like this. Keep it up!

Those models (especially the shotgun) look very strange in-game, I can't tell you why, tho'.
Anyway, keep it up !

Thanks for the encouraging words, bud. Yeah we're at pre-alpha stage right now so everything is still up for being modified, like the models and the textures. We'll fix it up soon.
