Geth Cannon

The Geth Cannon are part of the main armament of Geth Dropships.

A Cerberus project to fuse a VI with a human to create something to exploit the geth's religious beliefs. They called the geth ship Prometheus Station and it served to provide the geth subjects for the project. However after the project went wrong, Shepard and the squad had to deactivate the lockdown to get into Atlas Station, the VI gained control of the cannon and tried to defend the station with it.

Capabilities
Offensive

It is a massive cannon that is capable of destroying the M-44 Hammerhead in just one hit. The cannon is powerful and should be avoided at all costs.

Defensive

It possesses armor plating and is protected by a shield that is powered externally. The shield must be taken down before armor and the turret itself can be targeted.

Tactics
Because the cannon can destroy the Hammerhead in one hit, it is advisable to keep on the move. Use the red targeting lines on the ground to keep track of where it is going to shoot. This shot can take down one of the external generator's shields in one hit, but if you are too close, the Hammerhead will be destroyed or damaged. Stay still just long enough for the cannon to lock on, then use the boosters to jet away.

Once you have the shield down, use the Hammerhead's missiles to destroy the cannon once and for all. Just make sure to keep moving in order to avoid the cannon's blast radius.
