Stellaris: MegaCorp (DLC)

MegaCorp is a full expansion for Stellaris that hands you a new civic type and an entirely different win condition framing: instead of conquering the galaxy with fleets, you colonize it with contracts. The centrepiece is the MegaCorp empire type, which lets you establish branch offices on foreign planets, siphoning trade value back to your home economy without ever firing a shot. It is a commercial layer bolted onto Stellaris's existing sandbox, and when it clicks, it clicks hard. The trade value system gets its most serious workout here. Trade routes flow from your colonies toward your capital through a network of starbases, and piracy suppression becomes a genuine logistics puzzle rather than an afterthought. Stack enough Offworld Trading buildings across a rival's territory and you can quietly drain their GDP while they are busy building battleships. That asymmetry is the expansion's best trick. A well-run MegaCorp in the mid-game can field a surprisingly small military footprint and still be the most influential actor at the diplomatic table, which opens up build paths that vanilla Stellaris does not reward. New civics round out the corporate identity. Criminal Heritage lets you operate as a galactic syndicate, running branch offices in empires that would normally refuse your charter, at the cost of constant law-enforcement friction. Catalytic Processing and a handful of others tweak resource chains in ways that interact interestingly with later DLC content. The Ecumenopolis planet type, a city-covered world that converts food districts into industrial output, is also bundled here and remains one of the most satisfying late-game transformations in any Paradox title. Watching your core world become a planet-spanning manufactorum after 150 years of investment is the kind of payoff that justifies long sessions. The expansion is not without friction. The branch office mechanic requires your target empire to either consent via diplomacy or be weak enough to ignore your demands, which means the early corporate game can feel passive if neighbours are uncooperative. AI empires running MegaCorp civics are functional but do not fully exploit the commercial pressure the system allows, so single-player corporate warfare rarely feels as threatening as it should. The tutorial does nothing special to explain trade route optimisation, and new players may not realise the starbases-as-economic-infrastructure angle until a forum post enlightens them. For experienced Stellaris players looking to add an economic axis to their campaigns, MegaCorp delivers a coherent and replayable new identity. It pairs especially well with the Federations and Overlord expansions if you want to build a commercial hegemony through soft power. The mod ecosystem has also extended its systems meaningfully. If you have been running militarist playthroughs on repeat and want a fundamentally different decision tree to optimise, this is where to look. Diego, Scout Team
