3 tours of duty, 12 missions + 3 warmup missions offering challenging and Immersive gameplay in a lively area of operations;
Each mission is accompanied with a detailed operations order (OPORD’s in-game and PDF/TXT for forum briefings), AO map and additional intel;
Pre-configured TFAR for quick game start.
Media (PDF, images) to be used with forum postings (mission cover image, AO map, objectives, etc.).
Optimized for dedicated server play;
Challenging opponents;
Automatic detection of ACRE2/ TFAR, cTab and ACE3 add-ons.

Campaigns tours:
AO: Zargabad, Shapur, Takistan and Takistan Mountains (WarmUp)
Storyline: On 11 February 2019 the Taliban ceased to exist after a coalition forces UAV successfully targeted and killed the entire Taliban leadership council. The majority of Taliban fighters joined The Pashtun within the following weeks.

Tour 2
AO: Chernarus, Bystrica (WarmUp)
Storyline: Since CSAT Russia annexed the Lopatino district in 2014 a local insurgency faction emerged and declared the Sobor region as independent. Aptly naming it Soborisk. The Soborian Separatists quickly gained ground with the unofficial support of CSAT Russia. Over the years several attempts have been made to solve the crisis, but neither Chernarussian Government nor the Soborian separatists were willing to give in. Now, nearly 4 years later, CSAT Russia has issued an ultimatum to the Chernarussian Government: "recognize Soborisk as an independent state". All diplomatic solutions seem to have been exhausted.

Tour 3
AO: United Sahrani, Porto (WarmUp)
Storyline: Last week Monday, elements of CSAT’s elite 3rd Quds Brigade invaded the South Island of the United Republic of Sahrani (URS). The Sahrani Armed Forces (SAF) were taken by surprise. After a short and decisive operation, the SAF were forced to retreat to the north island. CSAT quickly took control of the South Island, including the Republic’s capital Corazol.
