Metro Exodus 3rd party site keys
We have been made aware of illegal stolen keys being sold by an unofficial
key reseller.
These keys have been obtained illegally from the factory where physical key
printing had taken place prior to the announcement of exclusivity with Epic
Games, due to the criminal nature of these keys, all unlicensed keys have
been deactivated and activation / download of Metro Exodus without the
executable file is no longer possible. In addition, the software will be
removed from the Steam library of any players using an unauthorised code. The
keys being sold on this platform are stolen goods, and are therefore illegal.
If you have been affected we strongly recommend you contact the seller who
sold you the unlicensed key and demand a refund.
The only supported key sellers for Metro Exodus were Humblebundle and the
Razer store.
Metro Exodus will return to Steam after 14 February 2020.
深银表示Steam上的序号全部都是从实体版工厂中非法流出的，
流出时间点是在宣布Epic独占之前。
这一批Steam序号全都会失效，已经使用的序号会从游戏库中移除，
如果有玩家因此权益受损，请去联系序号卖家寻求退款。
深银认可的地铁流亡的第三方序号商店只有HB与雷蛇(都是Epic序号)。
补充下，底下有人联系卖家之后拿到了一份Epic的序号....XD

非法流出被ban很合理便宜的序号本来就别乱买

个资流进来 腾讯发大财

笑爆

喔对了，这批序号可不便宜，独占消息出来后被炒到70欧

不便宜干嘛还去买？steam平台的吸引力有这么大到涨价卖都有人买喔？

+1无价

与其说steam吸引人 更像是epic故人怨吧

因为steam版原本只有预购才有吧

有阿，难道你要装EPIC？

难道你要装epic?
