The head of Respawn Entertainment, Vince Zampella, in an interview with reporters, said that so far he and his colleagues have no plans to develop the Titanfall 3 shooter. According to the director, at the moment this is not the most suitable environment.
It is not clear what exactly Mr. Zampella's understanding of whether the setting is appropriate or not is based on. Perhaps he is referring to the fact that there are already enough shooters on the market, and therefore another shooter may not gain popularity. On the other hand, the Titanfall series has a lot of fans who are looking forward to the continuation of their beloved franchise.
Be that as it may, in the foreseeable future, the sequel can definitely not be expected.
