LMG Gun Platform

The **LMG Gun Platform** is a Utility Tool used by the Engineer. It is an autonomous sentry turret that scans and engages enemies with short bursts of gunfire. In its MKI form it is colored a dark green. In its MKII form it has a bulkier profile and is colored dark red.

The LMG Gun Platform is carried on the Engineer's person and must be selected in order to deploy. It is placed into the world in a similar manner to calling a Resupply Pod, with a blue hologram indicating where it will deploy once selected. By default, no cone is indicated as the turret can scan 360° around itself, with the *Defender System* mod, a cone will be displayed in the hologram indicating the scan angle of the turret.
When placed, the Sentry will start out in an "unbuilt" state, appearing as a miniature cylinder on the ground. The Engineer (or any nearby Dwarf) must interact with it (holding the "E" Key by default) to assemble it into an operational state. The sentry makes a beeping sound once it is fully built and ready to fire.

Once built, the LMG Gun Platform will automatically target and fire indiscriminately at enemies who wander into its **Max Range**, firing in bursts. The sentry fire consumes ammo in its **Sentry Ammo Capacity** and will disable itself once this is emptied, an Engineer (either the sentry owner or other Engineers) can refill this magazine by HOLD `USE` on the sentry. The Engineer holds a limited supply of **Max Ammo**, and will fill the sentry as much as possible upon deployment.

Sentry Guns can be recalled back to the Engineer or designated new spots, done by either pressing HOLD `RELOAD` or selecting the LMG Gun Platform utility tool and placing the hologram again. Sentries can be recalled from any distance, but they have to physically travel back to the Engineer or their new spot. They will deconstruct and fly to their target as an unbuilt gun, and must be reconstructed before becoming operable again.
Press `reload` to switch between which sentry you'd like to redeploy when both are placed down with the *Gemini System* upgrade. Recalling a gun directly back to the Engineer will also return any ammo that other Engineers deposited. When using a resupply, Ammo in Sentries is counted towards the current ammo of the Engineer who owns it.

Sentries cannot friendly fire, even if a teammate deliberately crosses their line of sight.

### Modifications

There are four tiers of modifications and each tier has two to three upgrades. Only one modification can be equipped per tier.

### Trivia

* In the closed alpha, the Engineer would get four sentry guns with 200 ammo each, but they could not be called back and redeployed.
* Sentries will always idle sweep South West, regardless of which direction they were built or what enemy they were last firing at, unless they have the Defender System upgrade.
* When going to the next stage of Deep Dives, turret ammo is automatically restocked even if the Engineer hasn't resupplied in the prior stage.
* *Borderlands 2'*s Axton has the "Gemini" skill that allows the player to place a second turret.
