The Bulwark is a sturdy multi-weapon tower with three laser cannons of short to long range, allowing it to attack almost any target truly long-range artillery. It's tall enough to shoot over other defenses and units. The Bulwark's generous damage and thick armor makes it an effective focal point against enemy pushes, but make sure to keep it well supported.
Excels at dealing with swarms, but can also outrange even Mausers and Sharpshooters.
When threatened, the Bulwark can be turned to the OFF state, causing it to retract its weapons and bunker down into its armored shell, nearly quadrupling its effective HP. This helps it survive concentrated fire until it can be repaired.
