Beyond All Reason has a vocabulary that grows every season. If you just installed the game and dropped into a team lobby, the chat looks like a different language. People call out mex counts, demand engie repairs, mention AFUS lines and nano coverage, and you nod while silently opening a search engine. Every RTS community talks in shorthand. The problem is BAR's shorthand packs a lot of mechanical meaning into two or three letters. Here is a breakdown of the most common terms and what they actually mean in practice.
Mex is short for metal extractor. It is the building that pulls native metal from specific resource nodes scattered across every map. Mexes are the foundation of your economy. More mexes mean more metal per second, which means more units, more defenses, and more options. Losing mexes to an enemy raid is one of the fastest ways to fall behind in a match. Contested mex lines on the map define the midgame in almost every team game.
Engie is the builder unit. Short for engineer, engies construct buildings, repair damaged structures, reclaim metal from wreckage, and occasionally serve as emergency combat units in desperate situations. Every faction and commander has access to engies, and they are arguably the most important unit in the game. A player who neglects engie management will find their base crumbling while they wonder where all their defenses went. Good engie control means keeping builders alive, keeping them busy, and positioning them where repairs matter most.
AFUS stands for Advanced Fusion Reactor. It is a late-game energy generator that produces massive amounts of power. AFUS units are expensive, take time to build, and become priority targets the moment they appear on the map. If your energy icon is red and your economy is stalling, an AFUS might be the answer. If you already have plenty of energy from wind generators and standard reactors, building one is a waste. Knowing when to rush AFUS and when to hold off is a macro decision that separates decent players from good ones.
Nano turret is a specialized static defense that uses nanolathe technology to fire at targets with high accuracy and moderate damage. Nano turrets are power-hungry and require a stable energy grid, but they are efficient against both light and heavy targets. Unlike some defenses that excel against only one unit type, nano turrets are generalists. They are commonly built in grids or clusters that cover key approaches and force attackers to commit significant resources. Destroying a nano grid is usually a prerequisite for any midgame offensive push.
Macro refers to macro-management, the big-picture economy and production side of the game. If micro-management is controlling individual units in combat, macro is making sure you have enough units, enough resources, and enough infrastructure to sustain the fights. BAR heavily rewards macro play. A player with superior macro will overwhelm a micro-specialist simply by outnumbering them, even if every individual engagement is well-played.
Micro is the opposite end — hand-control tactics. Focus firing specific targets, stutter-stepping, dodging artillery shells, and managing unit formations. Micro matters, especially in duels, but it cannot overcome a large macro deficit in most team games.
Reclaim is metal and energy harvested from destroyed units and debris. When something blows up on the map, it leaves wreckage that engies can convert back into resources. Good reclaim play is like a hidden economy on top of your normal income. Players who consistently reclaim more from battles extend their advantage, and reclaiming from enemy dead units directly reduces the opponent's resource recovery while boosting your own.
Build power is a value assigned to constructors that determines how fast they build or repair. Higher build power means faster construction. Multiple engies working together stack their build power, which is why you sometimes see six builders swarming a single advanced structure. Understanding build power helps you decide whether to queue one expensive building with one engie or swarm the task with three for faster completion.
OpenSkill is the rating system BAR uses for matchmaking. It is not a ladder score. It is a mathematical model that estimates your skill level and adjusts after every match. The system handles teams, imbalanced player counts, and varying uncertainty between new and experienced accounts. You will hear people reference their OpenSkill number when discussing matchmaking.
This guide covers the ones you will hear in almost every lobby. Other terms like con (commander), com (the same thing, short form), eco (economy), rush (early aggressive push), and turtle (heavy defense, slow expansion) will naturally show up as you play. The important thing is not memorizing a dictionary. It is understanding what each term represents mechanically so you can act on the information when someone calls it out mid-game.
Learning jargon in a hostile lobby is miserable. Someone calls for nano coverage and panics when you do not know what to build. In Creed of Champions, people explain things without the sigh at the end of the sentence. You ask what AFUS stands for and someone tells you, helps you understand when to build one, and moves on without making you feel late to the party. The community treats new players as additions worth investing in, not liabilities to tolerate. That approach makes a genuinely steep learning curve feel manageable.
[Crd] Creed is a friendly community for many. It helps that people try to have fun over winning at all costs. While the spirit of competition is very much alive, people here seem to be more reflective and thoughtful of others.
