1. Hi everyone!
    This is a kind reminder to rate the builds you play or read. The ETA for the new rating system is not yet here, but if everyone active could rate 1 build per day, we can have everything rated in only 1 month! Don't feel bad about giving bad ratings with some constructive criticism :)
    Thanks in advance -- the MechSpecs team.

Frequently Asked Questions


What are the Code of Conduct on MechSpecs?

Welcome to the MechSpecs forums
, an MWO discussion forum, targeted towards topics regarding high-end mech customization, mix/maxing and analysis of game mechanics.

First, a point of clarification. We work on a Three Strikes System. Your third strike will be your last.

The people that participate here at MechSpecs are some of the best pilots out there. We have high standards for the discussion that occurs herein, and are quite unapologetic about it. If you feel our rules are stupid or arbitrary, we don't really care. If you don't wish to follow them, you are welcome to return to the official Mechwarrior Online forums and participate in the chaos over there.

The following is our Code of Conduct. You are expected to adhere to these protocols as they are put in place to make this community run smoother than some of the other MWO boards out there.

Please keep in mind that our goal is to promote good old fashioned clean(ish) fun, as well as informed discussion, or even debate, on all things related to MechWarrior Online; however we wish to do this in an environment free of toxicity and bullshit.


While this Code of Conduct is a guideline to help our moderation staff deal with problematic issues, it is by no means final; each case will be weighed by the Moderation Team and dealt with according to the actual severity of the incident. While we generally utilize a Three Strikes Rule, if you break these rules to a degree, that warrants immediate banning, trust that you will receive it.

How do I post a build on MechSpecs?

Your post should contain:
  • A correct title.
  • A 'Smurfy' summary of your build (see below).
  • An introductory text (try 2 sentences at minimum).
It's not allowed to create new threads for duplicate builds if it has had comments within 1 year or can be found on the first page. A build classifies as duplicate when the weapon loadout in the original post is identical, even if other factors like the engine and additional equipment are different.

Please only one build per post, so each can be rated/evaluated separately.

Why do I have left-over tonnage when I make a build in-game?

Don't follow smurfy by the book when it comes to armor.
Many mechs in-game have armor quirks, which give 'free armor' that doesn't weigh anything, in addition to the expected amount of armor a mech should have (for example: Annihilator, King Crab, Atlas). Smurfy doesn't take this into account.
If you build your mech using Smurfy's armor values, you will end up with left-over tonnage because you 'removed armor'.

In order to fix this, go for a fully armored mech and only then remove armor in the same way it's removed from smurfy (example: 43/56 armor on a location means 56-43 = 13 armor taken away).

Take note that many builders don't redistribute armor for the reason that it's inaccurate anyway. Figure out your own preferred front/back armor ratios.

If fixing the armor doesn't solve your issue, double-check if you're missing ammo, or using the right engine, for example.

Which pre-fix do I use for my build?

- Casual: This descriptor is probably going to be most common. Workable builds which are not necessarily top-tier for the chassis, but not a mess either. Examples of these builds are ATM Stormcrows, Medium Pulse Laser Hunchback 4Ps, et cetera.

- Budget: A descriptor for builds that are not expensive to build for a new player. Use this for builds which use a stock/common engine and don't get many upgrades for example, or omnimechs that do not change their omnipods too much. I expect this to be used relatively niche, but it could be good to have more of this type of builds on MechSpecs.

- Funny: The 'funny' descriptor is for all zany, wonky, mad scientist builds. Examples of these are: 6HPPC banshee, 6AC2 King Crab, or basically anything TheB33f thinks of.

The other two prefixes can have overlap with the previous ones, but are still useful to have seperately:

- Scouting: Specifically for builds to be used most effectively in the Faction Play scouting mode. These builds usually run less ammo due to less targets, and put it into the engine or weapon loadout.

- Invasion: Specifically for builds that are used most effectively in Faction Play invasion mode. These builds are usually meant for more sustained fights at longer ranges.

- Solaris: Only for builds to be used in Solaris gameplay, these will not rely on consumables and generally pack little ammo.

My Smurfy link doesn't work! Help!

In order for smurfy links to work correctly, follow these steps:
1. Copy the 'plain link' after saving your build
2. Make sure the link has 'https://' in front, as shown in the image below. A link with just 'http://' will NOT work.
3. Done.


PLEASE NOTE: You MUST do this right the first time otherwise XenForo will assume it is a regular link and parse it as a clickable line. If this happens to you, remove the link and start over. Alternatively,

1. Select the link XenForo has made.
2. Click the 'broken chain' symbol in the bar on top.
3. Insert the "s" into the link, as shown in the image and guide above.
4. Save changes.

How do I make a correct title for my build?

Make sure to include the Variant, an abbreviation of equipment on your build, and a unique name for your build in the title. There are many examples to use on the site!
We suggest that in order to get the best feedback on your build, you adhere to the standard format described below.


The standard format differs depending on the type of mech: Battlemech or Omnimech.
Battlemechs are the mechs where you can swap engines and change upgrades, such as the Battlemaster and Mad Cat MKII. They're organised into their own variants on this site.
Omnimechs are the mechs where you swap out entire components of different mech variants, such as the Sun Spider and the Stormcrow. They're organised into a single forum of 'builds' on this site, with an exception for builds that use hero omnipods, which cannot be obtained without owning the hero.

Battlemechs: VARIANT > NAME > ( > WEAPONS > EQUIPMENT > ENGINE > ) +Alt*

Omnimechs**: CT VARIANT > NAME > ( > WEAPONS > EQUIPMENT > ) +Alt* +Set***

JR7-D "Grimm Variant" (4xMLas, 2xSSRM2, AMS, XL300) +Alt
TBR-C "Burninator5000" (2xcLPL, 2xcSRM6A, 3xcERML, TC3, cAP) +Set

It's important to list how many of a certain weapon are equipped on a mech. This is done by putting a '#x' in front - where # is the quantity of that weapon - without a space.

CPLT-C1 Grimm Variant (2xLRM15A, 3xML, TAG, BAP, AMS, XL300)
* Instead of abbreviating the alternate build(s), you can simply put "+Alt" in the title if you have alternative variations on your build. 'Alternatives' are defined as mechs with the same weapon loadout, but different equipment or engine.

** Because Omnimechs have a fixed engine, They're not necessary in the abbreviation.

*** If you're using a build with only components of the same variant, indicate this by writing "+Set" behind your entire build title. This is handy if you make a build centered around set-of-8 quirks. Builds that do not have the 'set' suffix will require additional omnipods to be bought.

Why is a correct title important?

Our search engine can only find specific words. If you use a non-standard abbreviation for your title, it will be unlikely people will find your build through the search engine if they look for specific weapon types.

What happens to my build if my title is incorrect?

It will sit there looking silly!

However, if it has been reported, chances are a Moderator will come and re-title the build the way it is supposed to be done. Failing that, the Administrator will simply delete all your hard work because he is busy and you should know better.

How do I post an image on MechSpecs?

There are multiple ways to include an image on MechSpecs.
It is recommended to do this through an online image sharing platform.

1. Upload your image at a sharing platform (Imgur, Discord, etc.)
2. Copy the direct link.
Make sure that the link ends in ".png, .jpg, .gif, .bmp" or any other image file extension.​
3. Paste the link in your comment.
4. Done.

Screenshots posted on Discord can also be shared this way.

If you want to upload directly to MechSpecs, that's possible too through the 'upload a file' function.

NOTE: Imgur's Gallery function is NOT supported by MechSpecs. Again, use the 'Direct Link' as described in Step 2.

How do I get people to comment/rate on my posts?

The easiest way is to take initiative and comment on a recent build yourself, preferably similar to yours. You can find recently active builds for example by looking at the 'New Posts' on the top of the page. Make sure that your comment contains more than 'nice build, check out mine', if you want to get a helpful response.

Another way is to actively engage in our small community in the General section and make yourself known!

What do I do if I see a wrong post?

Please make sure to report all posts that do not adhere to the code of conduct (in your opinion), so that the moderators can deal with it swiftly.

If you see a wrong title or smurfy summary, you can report these posts or notify the thread starter of the FAQ!

You can use the following code to refer someone directly to the FAQ:
where '#' without apostrophes is the number of the question you want to refer to. The number can be found in the URL.

For example: the number of this question, which has the URL
, would be referred to as
The correct code (with number) is also described on the right of each individual question.
