The Original Deus Ex has so many usermade campaigns and little mods. Here, I will showcase the mods I encourage every Deus Ex fan to play. I will provide a short overview of the mod, an install guide, and a rating, with a Top 10 at the end!

Vanilla Madder by WCCC is a newer mod that adds a lot of content (check on the modpage!), but the one we're looking at here is the campaign loader! If you install the mods below correctly (no need for shortcut creation with this), you'll be able to EASILY run each of them through the New Game option in Vanilla Madder!!

Note: Only certain mods will work, ones excluded are Burden of 80 Proof, Terminus Machina, Revenge of the Sith, Invisible War Revised, Chasm, and The Nameless Mod (Use Revision). These have absolutely simple ways to install and play regardless (besides Chasm).

Overview: Redsun takes place in Japan. Play as Joseph as he breaks out of a lab and takes down the gangs of Otamachi-Ku. This has no voice acting.

Note: The mod replaces the map dx.dx and titlemusic.umx, so either back those up or just don't extract them.

Install & Playing: Download the zip and unzip into the directories. Create a copy of DeusEx.exe, and rename it to Redsun2020.exe. It should now allow you to play.
If New Game just takes you to the vanilla game, Enable cheats (Press y or t, delete say, and type "set human bcheatsenabled true" without quotes, the type "legend" without quotes. Next, click on 'load map', then scroll down to 21_Intro1, and doubleclick it.)

Overview: The so-called Meme Mod. Where quotes like "Paul, I thought you were a GEP Gun" and "We're 100% Black" comes from. Roam around Unatco HQ and a new Liberty Island map and interact with several characters from Deus Ex.

Rating: 10/10

Overview: A Polish horror mod. You experience a train crash and fall into a chasm. There you encounter ghosts, vicious spiders, and OH GOD WHAT IS THAT?!?! Very Resident Evil-like.

There is a translation, but it doesn't cover everything and feels like it was run through google translate. The puzzles and general gameplay are very cryptic. Not even I have completed this mod, so if you're up to the challenge, try this out.

Installing & Playing: Unzip the contents, create a shortcut of DeusEx.exe, rightclick it, click properties, and paste this where 'target' is:

"C:\Program Files (x86)\Steam\steamapps\common\Deus Ex\System\DeusEx.exe" INI="C:\Program Files (x86)\Steam\steamapps\common\Deus Ex\Otchlan\System\Otchlan.ini" USERINI="C:\Program Files (x86)\Steam\steamapps\common\Deus Ex\Otchlan\System\OMUser.ini"

(You might need to change the pathing if your steam install is different)

Rating: Now, since I haven't even completed it yet, I can't give a full rating, but since it's so confusing that I got stuck on the third map, it's a 4/10 for me.

Overview: A short parody of Human Revolution. Deleted a day after it's release for no apparent reason.

Installing & Playing: Download the zip on the right side, it should have it's own exe

Overview: This once lost mod is a re-imagining of the Deus Ex sequel, Invisible War. It takes place in a more grounded universe. This mod is pretty linear compared to other mods on this list. With the help of some fellow modders, we were able to restore and fix this mod to it's former glory! It features voice acting from it's creator.

Installing & Playing: Simply drag 'n drop the "IWR Community Update" folder into your Deus Ex folder! (NOT the "Invisible War Revised Community Update" folder both this text and that folder are in.) Navigate to \IWR Community Update\IW\System\IW.Exe. Run it!
