A charming 19th-century oil-drilling sim that layers resource management and land bidding into surprisingly deep, spreadsheet-friendly loops.

Turmoil - Deeper Underground is a DLC expansion for Gamious's oil-rush simulation, and if you already own the base game and finished its campaign feeling like you had the pipeline routing and land-auction meta figured out, this is the content that puts a new wrench in those plans. The core loop stays intact: you bid on land plots, survey for oil deposits, place derricks and pipelines, manage supply lines to buyers, and try to retire richer than your rivals. Deeper Underground adds new mechanics and map layers that push those decisions further down the decision tree, rewarding players who treat every drill placement like a resource-efficiency puzzle rather than a gut-feel guess. What makes this sim interesting from a strategy standpoint is the auction phase. Every season begins with a land-bidding round where information is deliberately incomplete. You are essentially making probabilistic bets on subsurface geology, and Deeper Underground tightens those margins. The expansion introduces deeper underground layers, meaning a plot that looks thin on the surface may hide a second vein worth chasing. That sounds like a quality-of-life gift, but it is actually a trap: drilling deeper costs more time and infrastructure, and the season clock does not pause for ambition. Knowing when to cut losses on a shallow field versus committing capital to a deep excavation is the kind of decision that separates breakeven runs from landslide victories. For newcomers wondering whether to jump straight into DLC territory, the honest answer is: start with the base game first. Turmoil's tutorial is genuinely respectful of your time. It introduces pipe-laying, valve mechanics, and town-service interactions at a pace that does not condescend, and the early seasons act as a soft sandbox before competitors start outbidding you in meaningful ways. Once the base campaign clicks, Deeper Underground slots in as a natural difficulty ramp rather than a confusing add-on. The AI competitors in this DLC are not spectacular, but they do apply bid pressure that keeps you from playing too slowly, which is often enough to force real time-and-capital tradeoffs. The mod ecosystem here is limited compared to the grand-strategy genre, and that is the honest ceiling of this title's longevity. What you get is a tightly scoped, replayable sim with a distinct visual style and a satisfying feedback loop. The 93 percent positive rating on Steam from a substantial review count is a reliable signal that Gamious delivered on what was promised. The Metacritic score of 73 reflects a game that reviewers recognized as polished but narrow in ambition. Both readings are correct. This is not a game that tries to model global geopolitics. It models one very specific economic moment in history and does it with enough mechanical depth to justify multiple campaign runs. If your gaming diet runs toward Rollercoaster Tycoon's build-optimize-reap rhythm rather than, say, Victoria 3's century-scale abstraction, Turmoil fits neatly into the lighter end of the strategy-sim spectrum. The DLC earns its place if you have exhausted the base game's challenge. Skip it if you are still learning the pipeline routing basics. Diego, Scout Team

Worth it if you have cleared the base game and want tighter resource decisions; skip if you are still laying your first pipelines.
