Rampart

Ramparts are stationary defensive turrets found on Grineer missions, armed with twin heavy machine guns to engage enemies. Unlike other types of environmental defenses, Ramparts can be directly controlled by Tenno players by mounting inside them, allowing them to use the Rampart's guns, though player-controlled Ramparts are limited to having only 200 rounds of usable ammo. While Ramparts are rooted to their positions, they can be aimed at nearly every direction.
