About the game
The U4 DLC for SubwaySim 2 adds a new line to the Berlin U-Bahn network — compact in length but distinctive in character. Players operate it from the driver's cab, experiencing another slice of Berlin from a fresh vantage point. It's add-on content for this train-driving simulation. Simuverse Interactive and 3DZug developed it, Aerosoft GmbH published it, and it's announced for a 2026 release.

Is Steam an official store or a keyshop?
Steam is an official store — keys come directly from the publisher or an authorized distributor.
Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.
Which key region should I pick?
Global activates everywhere. Regional keys (Europe, North America, RU-CIS) only work on accounts from that region — use the Region filter to match your account.
What is an activation platform?
The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
What's the difference between editions?
Standard is the base game; Deluxe usually adds an expansion or bonus content. The edition filter shows exactly that variant, with no mixed prices.
