How much does Bus Simulator 18: Official Map Extension for PC cost right now?

Bus Simulator 18: Official Map Extension for PC starts at €0.62 (€1.21 with fees) at Eneba, a Steam key, which is 91% under the €12.99 (no fees) it costs on the official store.

That €0.62 (€1.21 with fees) already includes the Gocdkeys10 coupon, so apply it at checkout or the store will show you a higher price.

There is a cheaper listing, €0.78 (€1.19 with fees) at Kinguin, but it is a Europe key and it will not redeem on a US account however good the price looks.

With 25 offers across 19 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.

At €0.62 (€1.21 with fees), Eneba is where this one settles.

Expand your Bus Simulator 18 experience with two brand-new municipalities set in the scenic Seaside Valley region. This official map extension introduces Kerststadt, a tech hub and university town, and Sonnstein, a tourist destination, each with distinct characteristics and transportation challenges. The expansion connects an airport and resort area to the city center, significantly expanding the playable map with fresh road networks and varied terrain.

The core gameplay loop remains true to Bus Simulator 18's meditative design: pick up passengers at designated stops, follow routes, manage your bus company's finances, and complete missions. The extension adds nine new missions offering approximately ten hours of additional content, with playtime varying based on player approach. You'll navigate new districts, unlock 20 additional bus stops, and encounter new characters like urban development consultant Michael Bach who introduces fresh objectives.

This DLC enhances the management and driving mechanics with enriched passenger voice-overs in English and German, providing greater variety during your daily operations. The multiplayer mode allows up to three friends to join cooperatively, helping develop your bus company together across the expanded map. You'll earn revenue through fares, manage routes, and gradually unlock new areas and services.

The Official Map Extension appeals to simulation enthusiasts and Bus Simulator 18 fans seeking substantial new content without a full sequel. It's ideal for players who enjoy the methodical, low-stress gameplay of running a public transportation business, appreciating attention to detail in vehicle handling and route management. The expansion rewards patient, systematic players who enjoy long-term progression and the satisfaction of building a thriving transit network.
