|Chapter 4: Stronghold|
Time of day:
"November 6 2041"
"Magnus decided to make a desperate bid to storm the stronghold that housed the Clayburn headquarters in the Caucasus, from which Sebastian led all Tkvarcheli operations. There was little chance of success, but Magnus saw no other way out."
Reach the circle at B4.
When approaching the indicated location, a new primary objective called "Break through the Gate" becomes active, and this objective will then require players to capture a control point at A4.
Break through the Gate
Destroy the gate at B4.
After capturing the control point at A4, survive for 2 minutes.
Destroy the Transformers
There are seven stationary targets to destroy within 6 minutes, and their locations are indicated on the minimap.
Destroy the Transport Helicopters
This objective appears approximately 15 seconds after "Break through the Gate" primary objective becomes active. The enemy will send three helicopters towards the buildings just south of the gate. Destroy them under 30 seconds to prevent them from spawning entrenched infantry positions inside the said buildings.
Destroy the Attack Helicopters
This objective appears at the same time as "Survive" primary objective. Destroy 10 helicopters to complete this bonus task.
