OPERATION COBALT: The Walking Dead Total Conversion

Recommended Posts

"When civilization ends, it ends fast" - Tobias





Greetings everyone!

Today I'm here to share with you my biggest project yet. Operation Cobalt.


What is Operation Cobalt?

I'm sure we can all agree there is a lack of "good" FPS/TPS games based in The Walking Dead universe, with very few that even give a glimpse of the Army/Gov in action. Operation Cobalt is an apocalyptic total conversion mod based in The Walking Dead universe, using Ravage and ACE3 as a base, and attempts to portray the efforts of the Military in Roleplay, Milsim, SP, Co-op, and even PVP environments with its included missions and content.

In The Walking Dead, Operation Cobalt is the name given to the plan devised by the U.S. Military in order to contain the spread of the infection. The initial stage of Operation Cobalt was initiated three days after the initial outbreak began in the U.S.A., with the deployment of military units into major urban areas (such as Los Angeles, California or Atlanta, Georgia) after the outbreak overwhelmed local law enforcement. Once deployed, the units would set up easily defensible 'Safe Zones' in urban areas such as Safe Zone India in Los Angeles or around the CDC in Atlanta. Medical facilities and refugee centers, such as those in the Los Angeles Arena and Raynard Community College, would also be set up to secure those believed to be infected, provide screenings for the injured and sick, and to act as bases of operations. Once these areas were set up, the safe zones would be used as a spring board to try to take back major metropolitan areas.


Included Missions/Scenarios (W.I.P)

Operation Cobalt comes with missions, scenarios, and campaigns that all take place in The Walking Dead universe and portray the events of Operation Cobalt, mostly during the first 30 days of the outbreak.


Operation Cobalt RPG (MMORPG) (Released, Alpha)



You RP one of two roles (You can swap between them): Military and civilian. Military personnel have to enforce laws, ensure safety in safezones, conduct missions, and attempt to take the region back from the dead and rebuild civilization. Civilians are basic survivors who must choose between a safe life within the safezones, resort to baditry, or start their own community away from the safezones.

In an effort to combine Milsim, Roleplay, and Zombie Survival, Operation Cobalt is the first ever gamemode meant to immerse the players into a heavy Roleplay environment based in the VERY EARLY stages of the zombie apocalypse, offering players an experience never before seen in Arma 3 while witnessing the fall of society. Rather than throwing the players into an open world with the basic survival mechanics with no real idea of who you are or what you're supposed to do, Operation Cobalt puts the players into one of two sides, where the civilians are free to start their own factions and communities while fighting the undead, pesky bandits, and struggling for survival in the beloved universe of The Walking Dead, and the soldiers need to enact Operation Cobalt.

The events of the Operation Cobalt RPG scenario take place in the following scenario: 17 days into the outbreak, the contingency plan was activated and the major city in the area was bombed. The remaining military units all withdrew to the nearest airbase. After failing to establish contact with high command, the remaining National Guardsmen decided to continue their mission and will begin a second and final push into hostile territory in order to contain, build, exterminate, and protect. Although the official lore never stated that the military attempted a second push, it was never denied or confirmed, therefore I’ve taken a few creative liberties!
