Planning a Mech Build

The first step in building your mech is planning. Do you want to build a combat-focused mech built for dealing maximum damage? Perhaps your Mechaneer needs a mech capable of hauling scientific equipment and taking specific measurements. Or maybe you earn a living as a field mechanic, and focus on equipment to make sophistocated repairs when far from a garage. Think about how you want to play, and how that relates to your mechaneer's personality.

Once you choose a focus, you should select a mech Frame and a Power Type. Read on for information on factors that you should consider when building your mech.

Tradeoffs to Consider

Frame Size and Speed

As the foundation of your mech, your frame has a significant impact on play style. Heavy frames provide more space for additional attachments, but are much slower as a result of their size. Large frames also offer a much larger target, and as such are easier to hit. Light frames are quick and hard to hit, but have very limited space for components. Standard frames are a good balance between the two.

Note that Plating also confers a speed penalty. Heavier armor can absorb a lot more damage before breaking, but will slow your mech down.

Power Type and Weapon Range

Mech play style varies quite a bit with power type. Mechanical mechs tend have short-range weaponry, while Electrical mechs tend to have the longest range. Steam-powered mechs have access to both short-range blunt force weapons which can compound damage and long-range artillery, so they're sort of a jack-of-all-trades.

Power Type Range
Mechanical Close range (50 ft to 600 ft)
Steam Any range (50 ft to 900 ft)
Electrical Long range (200 ft to 900 ft)

Control Software

The Components compatible with each software have distinct costs and benefits. As such, you'll want to choose software that fits well with your focus.

Software Component Tradeoffs
UMIX Very small, with low heat and power usage, but limited Processing and few Module slots
ProtOS Well balanced, with moderate CPU at reasonable resource usage
Ursa NT Bonuses to Targeting and lots of Module slots, but large and resource-intensive

Fuel Type and Power Plant Class

Power Plants are categorized based on what type of Power they generate and what type of Fuel they require. Some fuels deplete quickly, and some are much more scarce than others, so you'll want to pay attention to the type of fuel your power plant uses.

Power Plant Class Power Type Fuel
Ethanol Boiler Steam Ethanol
Ethanol Engine Mechanical Ethanol
Ethanol Fuel Cell Electrical Ethanol
Hydrogen Boiler Steam Hydrogen
Hydrogen Engine Mechanical Hydrogen
Hydrogen Fuel Cell Electrical Hydrogen
Lithium Ion Regulator Electrical Lithium Ion
Methane Boiler Steam Methane
Methane Engine Mechanical Methane
Nuclear Boiler Steam Nuclear
Nuclear Generator Mechanical Nuclear
Nuclear Turbine Electrical Nuclear

Fuel Tank Capacity and Depletion

Each day, your mech will use up an amount of fuel equal to its Used Power. If you run out of fuel, your mech will be unable to move or use attachments until refueled.

Some fuel types are much more energy-dense than others, which means that mechs using those types of fuel will typically need to refuel less often. The table below shows how much Power can be stored in small and large Fuel Tanks of each type.

Fuel Tank Fuel Capacity (Small) Capacity (Large)
Ethanol Tank Ethanol 10 20
Hydrogen Tank Hydrogen 20 40
Lithim Ion Battery Lithium Ion 30 60
Methane Tank Methane 40 80
Reactor Vessel Nuclear 60 120

Depending on how much power your mech uses, you may need to consider a larger fuel tank or even a different fuel type.
