Geothermal energy builds on Supreme Commander maps in Beyond All Reason

Supreme Commander maps in BAR feature geothermal vents that function differently from standard wind and solar energy. Building on a Geo map requires a completely different energy economy approach. Here is what you need to know about building around geothermal vents, when they are worth prioritizing, and how to structure your opening for Geo-dependent maps.

What makes geothermal maps different

Standard BAR maps rely on wind generators and solar panels for energy production. Supreme Commander style maps in BAR add geothermal vent placements, which produce substantial energy output from a single structure. A geothermal vent acts like a built-in fusion reactor that does not require the massive metal investment a fusion reactor demands.

This changes your entire opening. On a wind-dependent map, you build half a dozen wind generators to support a modest economy. On a Geo map, claiming the right vent positions can give you the energy output of multiple wind farms from two or three buildings. Players who understand vent positioning win early energy advantages that translate into faster factory production and earlier tech transitions.

Finding geothermal vents on the map

Geothermal vents appear as visible geological features on the map. They are typically located near the edges of plateau areas or along terrain transitions. Look for distinctive dark rocky patches or heat vent animations on the terrain surface.

The most important Geo spots are the ones closest to your starting position. You want to claim these with metal extractors and geothermal generators before the opponent does. On symmetric maps, both players get access to equivalent vent positions. On asymmetric maps, one side may have better vent access, which creates an inherent advantage you need to account for in your opening.

Structuring your Geo opening

A geothermal-focused opening on Supreme maps follows a different priority order than standard wind or solar openings:

Step one: secure the nearest geothermal vent. Your commander should move toward the closest Geo vent immediately after starting builder construction. Place a geothermal generator on the vent as fast as possible. The energy income from a single Geo vent usually matches or exceeds three to four wind generators combined.

Step two: claim metal extractors on and around the vent. Geothermal vents often sit near metal deposits. Claim as many of these as you can while the Geo generator finishes building. The combination of free geo energy and additional metal extraction creates a compounding economic advantage.

Step three: build your first factory with Geo energy backing. Because the Geo vent provides such strong energy income, your first factory can start building sooner and production runs faster than on wind-dependent maps. Queue units aggressively while the opponent is still building wind infrastructure.

Step four: expand to secondary Geo vents. After stabilizing your first base, push constructors to the next available geo vent. Each additional Geo generator multiplies your energy advantage and supports faster T2 and T3 transitions.

Geo versus fusion versus wind: the tradeoffs

Geothermal energy competes with fusion reactors and wind generators as your primary energy source. Here is the comparison that matters:

• Geothermal vents offer the fastest energy ramp. A Geo generator builds quickly and produces energy immediately. The build cost is moderate compared to fusion, and you do not need to worry about wind variance or solar placement constraints.
• Fusion reactors scale better long-term. Fusion produces more total energy than a single Geo vent, and advanced fusion scales enormously. But fusion requires significant metal investment and takes longer to complete. If you can run Geo while saving for fusion, you get the best of both worlds.
• Wind generators are the flexible fallback. Wind works everywhere. If you are on a map with weak Geo placement or all the vents are claimed, wind and solar fill the gap. A mixed economy of Geo plus supplementary wind is often the strongest setup on Supreme maps.

Common mistakes on geothermal maps

Not claiming vents fast enough. Geo vents are limited resources on the map. If you open with standard economy building while your opponent races to the Geo spots, you lose the energy advantage permanently. Prioritize Geo vent access from minute one.

Overbuilding on vents and neglecting defense. It is tempting to stack multiple buildings on a single Geo vent cluster. This creates a dense economic target that one enemy raid devastates. Spread some infrastructure away from the vent so a single attack cannot cripple your entire economy.

Assuming Geo replaces all other energy. A common mistake is treating geothermal as a total wind replacement. On most Geo maps, you still need supplementary energy production to support late-game scaling. Use Geo for early and mid-game advantage, then add fusion and tidal as the game progresses.

Learning Geo builds from experienced players

The BAR community has produced dedicated Geo build content that is worth watching. Content creators like Drongo and David Skinner have recorded gameplay where they run geothermal openings on Supreme maps, showing the build orders and timing benchmarks in practice.

Watch these replays and pay attention to three things: the path their commander takes to secure vents, the timing of their first factory relative to Geo generator completion, and how they transition from early Geo advantage to mid-game production scaling. These details reveal the rhythm of a proper Geo opening far better than reading a build order on paper.

Creed of Champions

Map-specific strategies like geothermal openings are exactly the kind of knowledge that takes a long time to develop on your own. Players who improve fastest do it by learning from people who have already figured out the timing and positioning. Creed of Champions runs training sessions where experienced players share build orders, walk through map-specific strategies, and review games together. Better teammates. Better games.
