Horizon zero dawn.
Guerrilla games went from making mid First person shooters (killzone) that barely sell 2 million copies to 3rd Person open world action adventure that has gone on to sell over 25 million copies and has become a high profile Franchise for Sony that is on par with some of the most popular open world franchises like the Witcher, Elder scrolls or Zelda.
The world of Horizon had deep sci fi lore, amazing creature design, great narrative and gameplay loop all with absolutely zero experience in 3rd person narrative driven open world action adventure.
It is quite impressive for a studio that was considered low tier upto that point.
