Gun turrets are heavy weapons that appear in all the Uncharted games.
Uncharted: Drake's FortuneEdit
Eddy Raja's pirates own three gun turrets in Uncharted: Drake's Fortune. They are seen close to the end of Chapter 5 and Chapter 6, but can also be found at the very beginning of Chapter 11. Unlike turrets in other games, the Brownings have unlimited ammo. However, they are weaker and have less leg protection. Their design is based on Browning M1919s.
Uncharted 2: Among ThievesEdit
Zoran Lazarević's troops use gun turrets to defend certain locations. The majority of them are soviet DShK heavy machine guns (e.g. Chapter 6 and Chapter 7). The turrets, which are used in later chapters (e.g. Chapter 19), are GAU-19/A heavy gatling machine guns. Unlike Uncharted: Drake's Fortune, these don't have unlimited ammunition. Instead, they have a certain amount of ammo depending on the difficulty.
The Heavy Weapons Troop uses a portable version of gun turrets, the GAU-19, which makes the player move slower when equipped.
Uncharted 3: Drake's Deception Edit
Turrets first appear in Chapter 12 in a set of two. The pirates use these DSHKs to keep Nate in cover, while other pirates either flank him or kill him when he runs out of cover. Katherine Marlowe's agents also use turrets on the top of trucks such as in Chapter 19 or Chapter 2.
Turrets are now a common appearance on the multiplayer maps. The turrets have 1000 bullets and cannot be destroyed. They also have shields; the only way to kill the user is to attack them from behind, or use explosives such as grenades or RPGs. It is also possible to shoot the gunner from the front by aiming at the unprotected upper frontshield.
The turrets on the Chateau are on either sides of the map. Two of them are at the Team Deathmatch spawns on one side of the map and are easily accessible from the beginning. Another one is on the other side of the map.
On the Airstrip, there is a turret near the Team Deathmatch spawn for the Villains mounted high. Parallel, and far on the other side of the map, is another turret which isn't available for use until a bomb hits the communications array above, in which case it falls over and allows players to climb it and reach the turret.
On London Underground, there is a turret right outside of the subway entrance, where the Villains first get off the train.
