A | Embark Studios 宣布，为了根据社区反馈进行“重大改进”，未来所有的 ARC Raiders 远征（Expeditions）都将推迟到 2027 年初。

(Xinhua/Sun Suying)Beijing's blue skies have become a visible sign of the city's progress in tackling air pollution, and behind that progress, digital technologies are playing an increasingly important role.
In 2025, Beijing recorded 311 days with good air quality and only one heavily polluted day, compared with 58 heavily polluted days in 2013, when the city officially began releasing PM2.5 monitoring data. The annual average PM2.5 concentration, a key indicator of air quality, fell from 89.5 micrograms per cubic meter in 2013 to 27 micrograms per cubic meter in 2025, a decline of nearly 70 percent.
The progress has drawn international attention. The United Nations Environment Programme has highlighted Beijing's experience in improving air quality as a model for other cities.
According to experts at the Beijing Municipal Ecological and Environmental Monitoring Center, the cleaner air is the result of a comprehensive system integrating environmental monitoring, scientific analysis, policymaking, regional cooperation and law enforcement -- with digital technologies now woven into every link of that chain.
MORE TARGETED APPROACH
Effective governance begins with accurate monitoring. Beijing has established a multi-level air-quality monitoring network. Figures show 35 standard monitoring stations across the city continuously measure six major pollutants, while more than 1,000 compact sensors deployed across communities and townships provide more detailed information on local air-quality variations.
The monitoring system was gradually built by the Beijing Municipal Ecological and Environmental Monitoring Center, one of China's earliest ecological and environmental monitoring institutions, responsible for monitoring Beijing's air, water, noise, soil environments and ecosystems.
The center has developed an analytical system that can identify around 125 components of PM2.5, covering most of its composition and helping researchers trace pollution sources.
"Source analysis helps us identify the major contributors to pollution at different stages, providing a scientific basis for policymakers to target key emission sources," said Li Yunting, technical director at the center.
Coordinated by the Beijing Municipal Ecology and Environment Bureau, the center has conducted four rounds of PM2.5 source analysis studies with other institutions, with results released in 2014, 2018, 2021 and 2025.
The latest analysis showed that regional transport contributed 57 percent of Beijing's PM2.5 pollution. Among local sources that accounted for the remaining 43 percent, vehicle emissions and residential sources represented the largest share of pollution, a distinctive characteristic of a major international metropolis.
The monitoring results have provided scientific support for a series of pollution-control measures. For example, Beijing has promoted new-energy vehicles to reduce transport emissions and adopted advanced techniques, including air-supported membrane structures, to control dust emissions. Meanwhile, coal combustion pollution, once a major contributor, has almost been eliminated and is no longer listed among the main sources, reflecting broader national efforts to reduce coal consumption, promote clean energy and upgrade heavily polluting industries.
With PM2.5 concentrations now at relatively low levels, further gains in air quality will depend on more targeted, science-driven approaches.

SMARTER ENVIRONMENTAL GOVERNANCE
Beyond monitoring pollution, Beijing has built a data-driven environmental governance system that links monitoring, regulation and enforcement in a closed loop from detection to action and follow-up evaluation.
Developed by the center and known as the innovative regulation-monitoring-inspection linkage model, the system integrates artificial intelligence, the Internet of Things, satellite remote sensing and vehicle-mounted monitoring technologies to pull together environmental data from multiple sources onto a unified platform.
"The system brings information that was once scattered across different departments onto a single platform," said Zhang Likun, director of the smart system division at the center, adding that this enables off-site enforcement and joint cross-sector actions involving housing, water resources and transportation, significantly improving the efficiency and precision of environmental management.
Using more than 30 intelligent algorithms, the platform automatically analyzes data and identifies potential pollution risks, based on which monitoring staff identify the most pressing problems and forward them to enforcement departments.
The approach has already drawn international attention. Clean Air Asia, an international nongovernmental organization focused on improving air quality across Asia, featured the system as a representative case study in its "China Air 2025" report. The model was also presented at the 2026 Better Air Quality Conference and recognized with the Certificate for Clean Air Best Practice Sharing.
China has integrated ecological conservation into its modernization drive. As the country speeds up efforts under the Beautiful China Initiative, Beijing's experience demonstrates how technology can support more precise, coordinated and sustainable environmental governance.
。这家开发了 2026 年初热门撤离类射击游戏的开发商在今天的 ARC Raiders 官网更新中宣布了其上线后计划的变动。更新确认了 Expedition 5 将于 9 月 8 日开启，并于 9 月 29 日结束，但在此之后，“锈带”（Rust Belt）将比平时更加沉寂。Embark 在公告中表示：“我们一直在仔细审阅大家对‘远征’的反馈。虽然我们在此期间不断进行改进，但我们意识到大家提出的一些问题，如紧张的撤离窗口、奖励结构以及新玩家的准入门槛，需要的不仅仅是小修小补，而是更大幅度的调整。它们需要更重大的改变。”“为了解决这些问题，我们需要暂停一段时间的‘远征’活动。Expedition 5 将是 2027 年初之前的最后一次远征，届时‘远征’将带着重大改进回归，以解决玩家最头疼的一些痛点。因此，如果你之前还在犹豫是否要出发，现在就是时候了！我们将在 9 月分享更多关于这些变化的细节。”“远征”是一种后期游戏机制，允许玩家有效地重置他们的 Raider 角色并从头开始，但保留少数继承物品。这是一个转生系统，自 2025 年 10 月上线以来一直吸引着 ARC Raiders 玩家不断回归，甚至鼓励经验最丰富的玩家再次挑战技能树。如果没有“远征”，玩家只能停留在等级上限处等待。

B | 公告最后向玩家保证，在“远征”暂停期间，他们的连续增益（buff）将继续保留。

C | 完成所有“远征”的玩家将获得 Zenith 套装。部分完成的 Caravan “将兑换为等值的 Ermal 代金券，可用于购买 Ermal 提供的物品，或与 ARC 零件及枪械贸易一起使用，亦可出售换取金币。”雪上加霜的是，Embark 还决定从 2026 年 9 月 22 日起暂停其每周的“试炼”（Trials）。这些活动将暂停两周，直至 10 月 8 日。自去年火爆上线以来，ARC Raiders 似乎一直拥有一批规模虽小但非常稳定的玩家群体，但其上线后的路线图并非一帆风顺。今年 5 月，Embark 确认将致力于每年进行两次重大更新，下一次更新 Frozen Trail 要到 10 月才会发布。尽管该更新被开发团队称为“迄今为止最大的更新”，并承诺提供新地图，但这些宏大的承诺并未能安抚不满的粉丝。许多人抱怨更新已经显得过于稀少且间隔太长，上一张新地图 Riven Tides 还是在 4 月份作为游戏的第二张地图加入的。暂停“远征”和“试炼”只会让粉丝们更加沮丧，即便他们也认同该功能确实需要认真的微调。一位粉丝表示：“移除游戏中唯一的进度系统（尽管它很浅显）是一个冒险的选择，但如果这是改进‘远征’必须做的，那就这样吧。

D | 但如果它没有以某种极具回报的方式进行彻底改变，我不确定他们之后还能做些什么。”另一位玩家补充道：“在地面上玩了 400 多个小时，我已经好几个月没碰这游戏了。你们拥有史上最好的游戏之一，却一直在搞砸。在目前的状态下它是无法玩的。希望能有 10 月份的大惊喜，但我并不抱太大希望。”还有一位粉丝说：“我肯定不会参加这次即将到来的远征，因为这本该是我的第一次。
