ArmA 3's story campaign will not be ready in time for the game's release, developer Bohemia Interactive has confirmed.
Bohemia said the delay is because of the game's "eventful" development, as well as the studio's struggle to work simultaneously on the game's alpha and beta versions.
"This was not a decision we made lightly," ArmA 3 project lead Joris-Jan Van 't Land says in a statement on the official ArmA 3 website.
"As game creators, we love developing and playing through campaigns so, to those awaiting ours, we say: sorry for the delay. After talking a lot about a focus on quality over the last year, it simply did not feel right to compromise now. Rather than pushing back the entire game, we launch this year with an awesome package - a splendid kick-off for the ArmA 3 experience."
With the campaign mode missing at launch, Bohemia said what remains is as follows: "The large island terrains of Altis (270 km) and Stratis (20 km), 12 singleplayer showcase missions, 3 faction showcases, 9 multiplayer scenarios, a set of 10 firing drill challenges, over 20 vehicles, more than 40 weapons, 5 factions, the powerful scenario editor and modding support."
The story campaign will then be deployed as a trio of free DLC downloads, entitled Survive, Adapt and Win. S
urvive will be available within the first month of the game's release, with Adapt and Win available in the months following.
In September last year, Two Czech employees of Bohemia Interactive were arrested and accused of spying on the Greek Island of Lemnos. The studio then delayed the game's release, citing "problems we simply couldn't have imagined".
In July this year Bohemia reported that hackers had withdrawn personal information from its user database.
ArmA 3 remains scheduled for release in the third quarter of 2013.
