Advanced Construction Vehicle
Advanced Construction Vehicle is a unit that opens you the window to most of the T2 economy and defensive structures. In most situations when you get one, start from updating your metal extractors, geothermal powerplants and then make fusion reactors and advanced metal makers. It has a higher buildpower than its T1 version and boosts your metal and energy storage by 100. On top of what its Kbot counterpart can build, the vehicle is also able to produce Advanced Fusions, the most powerful energy making structure in the game.
