Thank you and congratulations on your purchase of The Omega Concern's M2 Heavy Machine Gun Emplacement. Please read this manual and become familiar with the operation of this product.

The Omega Concern is dedicated to producing quality work at affordable prices, and we support everything we sell. All of our products are designed with the balance of impact on sim performance and ease of use in mind. If you find one of our products to have a bug, causing lag, behaving in unexpected ways, or otherwise being a pest, please let us know. If nobody tells us, we can't correct it.

You are eligible for all upgrades on this version, being version 1. Also, your feedback is valued! Your input directly influences the course of development and future features of Omega Concern products.

There is a technical support pass phrase in this manual, which you are strongly advised to use when first contacting support about this product. We do this because other people (not you!) don't bother reading the manual which contains the answers to their questions, thus taking our time and attention away from thoughtful questions not answered in the manual, such as yours. As always, emailing the support address above is preferable to offline IMs and notecards, both of which too easily get lost in the shuffle.

Important Features of Operation

The M2 Heavy Machine Gun Emplacement (hereafter referred to as the M2 Emplacement) is a placed weapon (who'd have thought?) and it is not to be attached to your avatar. If attached, it will not work.

The M2 is usable by fellow group members who have their tag set to the same as the emplacement. However, it has a limit of two (2) placements in a region. Attempting to rez, place, or drag over the border additional M2 emplacements will result in the newest one self-deleting.

Using the M2 Emplacement

From your inventory, drag out the object named "M2 Emplacement 1.0" onto the location where you wish to place it. Keep in mind if you intend to deploy sandbag walls, the footprint of the bunker is approximately 5 meters wide and long.

Options Before Manning

Repositioning, Rotating and Shifting the Bunker with and Independently of the M2 Tripod

  • Yellow chevrons move the entire thing 0.5 meters in the indicated direction. Curved orange arrows rotate it 30 degrees in the indicated direction - meaning it will rotate to 12 points in a circle, like a clock.
  • Red triangles will shift the bunker relative to the tripod and gun in the indicated direction.

Deploying Sandbag Walls, Roof and Camouflage Netting

  • The bars along the sides place and remove the sandbags for the four sides of the bunker.
  • The square toward the middle toggles the roof.
  • The plain palette button cycles through the colour palette, changing the sandbag colours, of which there are 12 in a variety of green, brown/tan and white/grey to suit most environments.
  • The net button toggles the camouflage net.
  • The net palette button cycles through the camouflage net patterns, of which there are four: Plain (which will be coloured along with the sandbags via the aforementioned colour palette), woodland, desert, and urban.

To man the emplacement, right click and the button face, tripod or bunker parts, but not the gun. Select "MOUNT".

After manning, clicking on the gun itself toggles shell ejection on or off. When not in mouselook, clicking on the tripod toggles stance editing, which is accompanied by text hovering over the gun to indicate that you are in stance editing mode.

Firing and Reloading

To fire the M2, go into mouselook and use the left mouse button. As you approach the end of an ammunition belt, you will see the end of the belt being fed into the gun. Once the belt is exhausted, the gun will automatically open up and load a new box of belted ammunition. This procedure takes approximately 15 seconds.


Sustained fire - approximately six belts with no pauses aside from reloads - may cause the barrel to overheat, and while it is overheated the gun will be unable to fire. You will have to wait until the barrel cools down enough to permit firing again, but be aware that the barrel will still retain heat and will not tolerate sustained fire nearly as long as it will when starting from a cold barrel.

Stance Editing

Once in stance editing mode, the movement keys are used to adjust the height of the gun and your avatar's position relative to it. You can set the stance by going into mouselook, aiming, and when you come out of mouselook, your avatar will remain in that stance. From there, you may make adjustments.

E/C (Page up/down): Moves the gun itself up/down. This height is universal for each of the six stances.

There are six stances that can be adjusted with the WASD keys, which relate directly to the range of gun elevation, in degrees: -15, 0, +15, +30, +45 and +60.

Using the WASD keys adjusts your avatar's position for the stance you are in:

  • A/D (Left/Right): Moves your avatar further from or closer to the gun.
  • W/S (Up/Down): Moves your avatar up or down relative to the gun.

As avatars vary in height and reach, your avatar's adjustments are stored with each stance. Meaning, an adjustment you make for the -15 degree stance will not be applied to any other stance.

Once you've perfected your avatar's fit with the gun and stances, you may take the emplacement back into inventory and your settings will persist when you re-rez it.

Death and Destruction

In OCS mode, you are still vulnerable to (accurate) small arms fire, and large explosive devices, such as those intended for use against armor and fortifications. Additionally, the M2 Emplacement can be destroyed by heavy OCS weaponry. In the event you are manning the emplacement at the moment of its destruction, fatal damage will more than likely be inflicted upon you.


The M2 Emplacement has been extensively tested and is free of any known scripting bugs. If you believe you have discovered a bug, please contact This email address is being protected from spambots. You need JavaScript enabled to view it. and provide, with as much detail as you can, step-by-step instructions for reproducing it. Things don't get fixed if we don't know what needs fixing. :)

  • To rez the M2 Emplacement, the parcel in which you are doing this needs to have at least 55 prims/prim equivalent free.
  • If things aren't rezzing for you, such as the gun rounds check your group tag and the group tag of the emplacement to make sure it is harmonious with the area you are in. Some viewers give the option of always creating objects under the group to which the land is set, which may cause you issues if you aren't expecting it and travel to another parcel that requires a different group.
  • If you seem to be doing no damage in OCS, first make sure you are wearing an OCS HUD.
  • Sounds, and not being able to hear them: If you're using a Viewer 2 or 3 based viewer, the default sound settings cause sounds to carry a few meters at most, then be unable to be heard. If not already showing, press Control-Alt-Shift-D and make the Advanced Menu appear. From that menu, select "Show Debug Settings." In the box, enter or locate "AudioLevelRolloff" and try setting it between 0.040 and 0.200 for better hearing.
  • Asset corruption happens. Rarely, a copy of something will become corrupt and behave in very strange ways. The first thing to try is to unpack a fresh copy of the item from the box in which it came. If that doesn't solve the issue, you can have another box of the same item sent to you via the service kiosk at The Omega Concern's main store. Failing that, contact the support address and request a new box be sent to you and you will receive it as soon as possible.
