进度

《都市：天际线2》的进度包括三种形式：里程碑、发展和地图区块

里程碑

根据人口和幸福度增长，游戏内每天可以被动获得16次（即每1.5小时一次）成长点（XP）。另一方面，采取特定行动可以立即主动获得成长点，诸如放置/升级服务建筑，建设地标建筑，或是扩建城市道路网络。积累足够成长点可解锁里程碑。每解锁一个里程碑可获得资金奖励、发展点、扩展许可，提高贷款额度，解锁新的城市服务、政策和管理选项等。 自1.1.5f1开始，下列专门产业区将默认开局解锁：牲畜养殖、谷物种植、林业以及 石材开采

发展

Main article: Development Tree

Transportation development tree

When a new service in unlocked via a Milestone, only its basic buildings and features will be available. Additional buildings and features are unlocked via the Development Tree using Development Points. Unlocking all Milestones will grant enough points to ultimately unlock the entire Development Tree.

Each Development Tree is divided into different Tiers and has a varying number of Nodes to unlock. Tier 1 nodes cost 1 point, tier 2 nodes cost 2 points, tier 3 nodes cost 4 points and tier 4 nodes cost 8 points. The first Tier includes the basic buildings and functions of the service and this Node is automatically unlocked when you gain access to the service. As an example, when you first unlock Public Transportation, you have access to both Buses and Taxis as well as things like Stops and the Line Tool. The subsequent Tiers offer more advanced options which cost more Development Points to unlock, but provide you with new options.

Some services, such as Public Transportation, have multiple Branches with different options, and while you need to purchase the previous Nodes on a branch to unlock the next one, you do not need to purchase everything in a Tier to move on. For example, you can gain access to the International Airport without needing to unlock Water, Tram, or Subway transportation - as long as you have enough Development Points to afford it.

地图区块

Each map is made up of 441 tiles of 0.4km² each. When creating a new city only 9 tiles will start purchased and additional tiles can be purchased after the first milestone is reached. Each tile costs 1 Expansion Permits and Money that scales with the buildable area. Multiple tiles can be selected at once for purchase by clicking on them or dragging a selection area. Selecting one or more tiles will list the total buildable area as well as natural resources. Newly purchased tiles do not have to be connected to each other.

The cost for each new map tile is calculated based on a series of factors, including:

• Number of existing map tiles unlocked (including those apart of the pending purchase if selecting multiple at once). Cost per tile appears to increase by ₡125 per map tile unlocked (needs to be validated by assessing source code).
• Amount of building area in map tile(s) unlocked. Cost is approximately ₡1,184 per 10,000m² (0.1184 ₡/m²).
• Amount of resources within map tile(s) unlocked. Cost is approximately:
  • ₡18.6 per ton of Wood or Ore
  • ₡55.6 per kg of Oil
  • ₡53.9 per m³ of Groundwater
  • ₡16.9 per m² of Fertile Land.
