看起来我们得等个一个月才能拿到新的版本

原文:What's new* in the relaunch version?
1. Updated scripts for Muv-Luv Alternative- There will be one more final text update, but this won’t affect the save data at all, so feel free to progress with the story.
2. Muv-Luv Extra+Unlimited will be available for $29.99!(from $34.99)
The games are 30% off until March 15, 2018
Help spread the Luv to your friends and family by sharing our social media posts!
*The new Steam cards, and backgrounds will be implemented after the release. We were rushing to relaunch the games so we weren’t able to finish all graphical assets in time. Rest assured we’ll update everyone here on Kickstarter, social media, and Steam once they’re available. Please look forward to it!

新版本降了价，然后打了折，还有新的卡片(还好以前已经合了徽章。。。)
当初说一个礼拜只能解决，结果用了一个月(或许还不算差？)，新版本的游戏说三月底之前如果不能给我们，要通过steam API解决
我想问问steam API是什么？
