NOTE: This article is about the titular campaign of ArmA 3's Apex expansion pack. For a walkthrough on the campaign's sixth mission, see Apex Protocol (mission).


ArmA 3's Apex Protocol campaign has players take control of a four-man team of CTRG operatives. It was added with the release of the Apex DLC.

A tsunami caused by a mysterious subsea earthquake has devastated Tanoa, a province in the South Pacific island nation of the Horizon Islands. CTRG has been deployed to the island in search of answers following an insurgent uprising, and to discover the origins of the unusual tsunami strike.


Take on the role of a NATO CTRG special operator in the 1-4 player "Apex Protocol" co-op campaign. It consists of highly replayable missions, featuring a drop-in / drop-out multiplayer structure, and the difficulty scales up or down based on the number of players.

Insurgents freely roam and terrorise the province's citizens.

The South Pacific island nation of the Horizon Islands suffers a major disaster when a tsunami devastates the islands, displacing thousands in the process. An organised faction of criminals known only as the "Syndikat", have taken advantage of the chaos to terrorise locals and run rampant throughout the Tanoa province, greatly expanding its control over the islands.

One of Syndikat's key leaders is a former member of the "Red Tiger" group named Solomon Maru, codenamed "Warlock", who attempted to topple a North African government through a coup almost a decade ago.

With the situation turning into a humanitarian disaster, NATO forces are soon sent in to assist with the crisis and take part in the "Safe Horizon" joint exercise with the local authorities. In reality, this exercise is being used as a cover for CTRG's Group 15 to conduct its clandestine operations, attempting to discover the source of the Syndikat's disproportionally large quantity of military-grade equipment.

CTRG proceed to the safehouse where "Warlock" is presumably located.

With the assistance of a HUMINT asset known as "Blue Cap", CTRG teams Raider 1 and Raider 2 are able to disrupt Syndikat operations by destroying ammunition caches along with ambushing a convoy en route to attack a civilian village.

Eventually, enough actionable intelligence is gathered and Warlock is revealed to be arranging a meeting at one of his safehouses in the village of Namuvaka. CTRG raids the safehouse but only discover the bloodied and bruised corpse of Blue Cap.

Suddenly, what appears to be a platoon of Chinese black ops ambush the operatives. Fortunately, they manage to repel the attackers and successfully escape from the ambush, carving their way through more Syndikat reinforcements attempting to intercept them.

Raider 1 in position to breach the hideout where Keystone is being held.

Following the attack, both Raider teams locate and rescue their primary objective; callsign Keystone, who turns out to be Captain Scott Miller of Group 14. Previously thought to have perished in the aftermath of the failed operation on Altis, it is revealed that his main mission was to retrieve a seismic device being developed by CSAT scientists, codenamed "Project Eastwind".

Miller's investigation uncovered that the same Chinese operatives who ambushed Raider 1 and 2 were a part of a CSAT SOF unit named "Viper Team". They intentionally armed Eastwind on Tanoa and were the ones responsible for causing the subsea earthquake which initiated the tsunami. All of this was being carried out as part of CSAT's so-called "Apex Protocol" strategy, a series of plans aimed at destabilising countries friendly to the West.

CTRG attempt to extract Miller via helicopters, but are ambushed as the arriving helicopter takes heavy fire and is forced to abort its landing. All the while, Viper continues to hunt down the operatives. Eventually, they manage to extract successfully with boats.

CTRG commence their assault on Sosovu Island.

Following his rescue, Raider elements proceed to assault the "black site" being used by Viper somewhere on Sosovu Island. Fighting they way through each village one by one, Raider 2 finally secures the primary site and discover that Syndikat has double-crossed CSAT. They intend to hold Eastwind as ransom in order to blackmail CSAT.

Both Raider 1 and 2 track the Eastwind device to the Blue Pearl Industrial Port where Syndikat are arming the device to cause yet another earthquake. With time running short and seismic activity increasing, both Raider elements attack the port by first disabling the main power to the area, and then finding and assassinating "Warlock" and his senior lieutenant once and for all.

Viper launch a last-ditch counterattack against CTRG.

Raider 1 manages to secure the secondary code while Raider 2 obtains the primary codes, all the while fighting through the remaining insurgents. Raider 2 then manages to locate the Eastwind device where they, along with Raider 1 and Capt. Miller, are forced to hold off against waves of Viper who launch one desperate all-out assault on their position.

Luckily, they are repelled with the aid of Group 14's members, and both Raider teams are eventually extracted with the Eastwind in tow - now finally "in safe hands".

    • Beat all six missions - including the "intro" mission, Keystone, cooperatively with two or more human players. It does not have to be performed in chronological order nor with the same team of players.


  • It is the first and only multiplayer-oriented campaign in ArmA 3.
  • Apex Protocol takes place exactly one day after the ending of The East Wind and at the same time during the events of Remnants of War.
    • It is mentioned by Miller himself that he has been on Tanoa for at least four weeks prior to the start of the campaign investigating CSAT's activities in the region (where he was eventually captured by Syndikat).
    • This seemingly contradicts the events of The East Wind, as even if Miller left the Republic of Altis and Stratis immediately following Nikos' rescue in Attention Deficit and the NATO counter invasion on Altis (Beyond Recognition), he would have at most been on Tanoa for only ten days; not including travel time.
  • An offline singleplayer version was planned by the developers but was later scrapped for logistical reasons. The development team has officially stated that there are no plans to revive the singleplayer version.
The information below details unused, pre-release or removed content.
  • According to an OPREP published after the expansion was released, Apex Protocol was intended to have featured a mission involving the gunship configuration of the Blackfish VTOL.
    • Presumably, the Blackfish (either AI or player-controlled) would have provided fire support for the players on the ground as they progressed through the mission.
    • E3 2016 trailer with (presumably) a depiction of the cut mission.

      A scene depicted briefly towards the end of Apex's teaser trailer further reinforces its existence, as it shows the players pushing through a Syndikat stronghold while a loitering Blackfish provides support.
    • Although it is not known as to which mission specifically that the developers were referring to, a likely candidate would have been Extraction, as the mission's setting (loosely) matches the scenario described in the OPREP.
