One of my great gaming sins has been managing to somehow skip out on the entirety of the Dynasty Warriors series, but now that one of them is releasing on Steam, my days of being uninformed about all things Lu Bu are numbered...
A rocket flies towards a tiny meteor, and a robot and sentient balloon are delivered to its surface. The rocket flies off. A young girl is crying uncontrollably. Several decades later, a friendly alien flies by and notifies the robot that it needs to prove its humanity or its entire race will be scrapped. This is Doki-Doki Universe.
