Terraforming Mars - Hellas & Elysium (DLC)

Hellas and Elysium is a map expansion for the digital adaptation of Terraforming Mars, and if you have already put serious hours into the base game, these two boards are where the strategy actually deepens. The original Tharsis board has a fairly predictable geography that experienced players can optimise around almost by muscle memory. Hellas, set in the southern polar region, breaks that comfort zone immediately: its milestone and award structure rewards aggressive early spending, and the south pole ocean tile can be placed to trigger temperature bonuses in ways the base board never allows. Elysium, on the other hand, sits at the opposite end of the planet and front-loads its milestones toward production engine players. Both maps force you to re-evaluate which corporations and project cards are worth drafting, which is exactly the kind of lateral pressure a good expansion should create. From a decision-depth standpoint, the payoff is real. Hellas especially changes the calculus around ocean placement, because triggering temperature via the pole tile can accelerate your terraforming rating in a way that compresses game length. That compression is a double-edged thing: faster games mean less runway for slow-build corporation strategies like Credicor or Interplanetary Cinematics, and more room for aggressive point-scorers. If you are the kind of player who builds spreadsheets around generation-by-generation resource curves, Hellas will hand you a new set of numbers to crunch. Elysium is somewhat friendlier to familiar strategies but rewards players who push toward the southern milestones early rather than coasting. The digital port carries the same technical baggage as the base game. The AI opponents are serviceable at teaching you what the cards do, but they do not adapt well to either new board's specific tempo demands. You will outpace them once you understand the geography, which means the long-term replay value is almost entirely in async multiplayer or pass-and-play sessions with people who also own the DLC. That requirement is worth flagging: both players in a multiplayer session need the expansion for these boards to appear, so check your group before buying. The UI is functional rather than elegant, and the modest visual differentiation between the two boards means you are reading tile text more than reading the map at a glance, which slows down the early-turn planning phase more than it should. For newcomers, a word: do not buy this before you have finished a handful of full games on Tharsis. The base board exists to teach you how milestone triggers and award racing interact with the core terraforming parameters. Jumping straight to Hellas without that foundation means you will be making map-specific decisions without understanding what you are trading away. Come back after maybe ten to fifteen games on the original board, and these maps will feel like a genuine unlock rather than an overwhelming add-on. That is the correct order of operations. Bottom line: if you are past the learning curve and want something that makes your existing card knowledge feel fresh, both boards deliver. Hellas is the more disruptive and interesting of the two. Elysium is the safer pick for players who want variation without full strategy reconstruction. The mixed review score on Steam reflects frustration with the digital client's rough edges more than the quality of the board design itself, and that distinction matters when you are deciding whether the expansion is worth picking up.
