Projekt#1514 is the name of a new teaser Namco published earlier.
We're not quite sure what it is, but the teaser trailer shows a city in what looks to be a post-apocalyptic event. There are sounds of a distant battle, and the logo has a military industrial design.
"Which world is this? What are they fighting for?" is the tagline. The project is developed by DIMPS, the Japanese studio behind the Dragon Ball Xenoverse games.
The official website sadly doesn't have any extra information, only a promise of more info later. There's a link to a newsletter, though, if you want to get notified when Namco does release new details.
When it's fully revealed, Projekt1514 will be the second new IP from Namco announced this year, after Code Vein.
