Combat Engineer

Combat Engineers are a more expensive and powerful 'jack of all trades' version of Builders:


 * Can travel over water like a hovertank
 * Can construct some T2 buildings directly (T2 Extractor, T2 Land / Sea / Air Factories). Price is equivalent to building, then upgrading the T1 facility, but direct T2 construction is faster than waiting for the upgrade to complete.
 * Can directly construct Heavy Tank and Amphibious Jet units
 * Construction and repair rate is faster than the basic builder
 * Can heal units in addition to buildings, with a healing rate approximately 2X faster than the $1500 Repair Bay.
 * Slowly self-repairs
 * Have a weak ground attack capability, and can attack submarines.
 * Generates $1 / second via a built-in Fabricator. For reference, Fabricator buildings and upgrades cost roughly $1000 per $1 of revenue, or extractors provide even better ROI, at $100 / $280 / $500 / $800 per $1 of revenue for T1 / T2 / T3 / Overclocked extractors.

Combat Engineers are not a cost effective land combat unit, due to costing $4500, but they can defeat an $800 Heavy Tank in 1:1 combat, with their superior health (1000 vs 600) overpowering the tank's superior DPS rate (36 vs 43). Most of the time, Combat Engineers are used as second-line healer units, but in a pinch, their attack can be used to supliment the main army, or to defend the home front against solo harassing units.

Notably, Combat Engineers hard counter submarines, being the only unit able to attack a sub without being attacked back. Additionally, Combat Engineers are the only sub attacking unit that can be produced without having a Sea Factory. This makes Combat Engineers indespensible for regaining sea access in situations where massed submarines have seiged your coastline, destroying all Sea Factories as they are being built.
