FO Logo GreenFrag.Ops is a semi-realistic FPS total conversion mod for Unreal Tournament 2004. Players can choose between two teams, Special-Ops and Mercenaries, each has an arsenal of customizable weapons to choose from. FO takes place in a fictional near future environment, with missions located worldwide. The gameplay in this modern tactical shooter is round based with different objectives for each mission. Be warned, Frag.Ops contains extremely fast paced action.

Key Features Include

--WYSIWYG Aiming System - FO is the pioneer of the fully physical recoil system, in other words no aim-error or "conefire". This means as long as you adjust for recoil you will hit what you are aiming at.
--Medal Award System - Medals are awarded to players achieving certain goals, the medals have different rewards attached to them like cash and extra abilities. Achieving the highest marksmanship medal grants you access to the Golden Eagle a one shot kill pistol. Earning medals became a huge part of play, thus it wasn't surprising to see another game, D.I.C.E.'s Battlefield 2, make use of a medal system in an almost identical way 2 years later.
--Trait System - Select from multiple RPG like traits for your character, each have there unique pluses and minuses.
--Action Point System - These points allow you to sprint, making you run faster for a limited time, they can also help you stabilize your scope by holding your breath. You recharge these points manually by resting. The amount of action points you have depends on armor type, traits, and medals.
--Customizable Weapon System - The game offers 24 unique weapons divided evenly between the 2 teams except for a few shared weapons. Weapon can be upgraded with different options and attachments such as scopes, silencers, different ammunition, akimbo sub-machine guns, night vision scopes, laser sites, bayonets and even poison for your machete.

Other Notes

Frag.Ops was published in UT2004 Editor's Choice Edition along with other top mods. Unreal Tournament ECE was released on Sep 21 2004.

On the first day of release FO was downloaded over 20,000 times in the first 12 hours. Afterward it would remain the highest-played mod in UT2003 history, and continue on to UT2004 as the second-highest (March 2006).

Please note that Frag.Ops was designed as an online multiplayer game. There is a single player botmatch, but it was not developed vary far and does not reflect the intended gameplay that you would see online.

The official FO website has been shut down and Frag.Ops is no longer being developed, but dont let that stop you from checking out this classic mod.
The Frag.Ops Team would like to thank all the players and we are happy so many people enjoyed playing FO.

Kind late to comment, but is worth it to download 2.16 for the War mode. That one is just plain fun & unique, even though bots are not too bright :\.

Good question, there were many factors that contributed to War mode being dropped. One of the main reasons was we were trying to concentrate are game down to our best, most polished and most complete stuff. This meant just having our main game-type and our best maps. We did add war mode elements to certain maps; Predator for instance was converted and had vehicles. Err.. I guess that was the only one but we had plans to do it in more maps. Unfortunately our 2.2 comeback didn't last that long and our team moved on. You can always download 2.16 if you would like to play war mode, it's fairly easy to find using google.

First make sure you have the latest patch for UT2004 which is 3369.

To start the game you can click the .bat file located C:\UT2004\FragOps then Play-windows.bat
or set up a desktop shortcut with the location
C:\UT2004\System\UT2004.exe -mod=FragOps
(May need to modify this depending on where you installed UT2004)
Alternatively you could make a copy of your ut2004 desktop shortcut if you have one, rename it and edit the properties adding a space then -mod=FragOps

For Linux or Mac check the readme C:\UT2004\FragOps
README-v220.txt under Technical Information
