In Mafia Wars Moscow, businesses work a lot like they did in Cuba. So far there are three businesses. Unlike Cuba, they are unlocked as you progress through the story. You can buy the cigarette business after you unlock the third chapter in episode 1, and you can buy the Black-Market Car Lot after you unlock the third chapter in episode 2. Here are the businesses (text & pic):
Unlicensed Taxi Stand: You get this just by going to Moscow. Earns 15,000 Rubles every 3 hours.
Cigarette Smuggling Ring: Purchasable after unlocking Chapter 3 in Episode 1. With no upgrades it produces 30,000 Rubles / 3 hours.
Black-Market Car Lot: Costs 3,750,000 Rubles, purchasable after unlocking Chapter 3 in Episode 2. With no upgrades it produces 60,000 Rubles / 3 hours. Fully upgraded it produces Exotics and earns 336,000 Rubles every 3 hours.
Will update as more chapters are released!
