Rad Labs Meduza Auto Sentry

The Rad Labs Meduza Auto Sentry is a tool that deploys a fully autonomous tripod-mounted perimeter defense system that holds a large amount of ammunition and can be placed on the floor or on objects depending on the tactical situation. The Sentry Gun is able to identify friend from foe, which allows team mates to walk safely within its cone-like range, as long as there are no enemies detected in it. However, if an enemy comes within range, the sentry will fire regardless of player presence and damage allies if they are in the way. Use with caution.

The cone of the Sentry Gun has 3 colors that visually communicate the status of the gun to the players:
 * Green : Sentry is active, ammunition is available, and scanning the area for targets.
 * Red : Sentry has identified an enemy/enemies and is engaging the target(s).
 * Grey : Sentry has run out of ammunition and is in idle mode. All functions ceased until further action is taken. Additionally, the Sentry will emit loud beeping sounds as well.

The Auto Sentry variant fires fully automatic.

While the Auto Sentry's damage leaves something to be desired, it really shines in its ability to stagger enemies, its high fire rate means that it can shoot many enemies in quick succession, mixed with its medium range means that if it is placed in a good spot, eg: a long hallway, it will have time to shoot many enemies before they can reach your position, which will slow them down to either allow you to finish completing scans, or just a longer amount of time to shoot them before you have to move back to another position. Because of its range and fire rate it is a good idea to place it facing where the enemies are coming from to prevent friendly fire.

Compared to the Burst Sentry, the Auto sentry uses tungsten bullets like the Autopistol for an increased stagger effect but deals lower damage in return. Combined with the huge ammo capacity it can delay parts of incoming waves or help stagger larger enemies to support the team. Might act as a replacement for C-Foam in situations where normal doors are either unavaiable (e.g. destroyed) or cannot be kept closed with C-Foam.

It was released as a rundown specific tool in the Rundown 004 / Contact update.

Pros

 * Adds direct (although low) firepower to the team.
 * Great ammo capacity.
 * Takes advantage of the sleeper's weak points if shooting in the back or the head.
 * The gun's targeting scanner can warn on where enemies are coming from.
 * Constant rate of fire.
 * Good range.
 * Excellent at staggering enemies.
 * Expand for Spoilers => Great at keeping Chargers and Big Chargers at a distance to prevent their hard hitting melee attacks.

Cons

 * Requires constant tool resource packs to upkeep.
 * A badly placed sentry will be either ammo inefficient or useless (enemies running in front or past it).
 * If enemies are moving side-to-side the sentry has issues hitting them, resulting in ammo inefficiency.
 * Can only fire targets in front of the gun.
 * Poor damage, requiring alot of ammo to kill striker sleepers.
