Guess we've been missing 'em.
According to a recent blog post at developer Naughty Dog's site, it seems the studio has been dropping hints on the Internet. The exact statement came from web developer Jason Paul:
"I’m just surprised no one has yet to find some of the secrets we have dropped around the internet…"
This could relate to future downloadable content for The Last Of Us , but we already have the Left Behind DLC and future content will likely be multiplayer-oriented. That's probably not big enough to warrant little hints and secrets, so most are assuming that Paul is referring to Uncharted 4 hints. If so, we're willing to bet that a lot of gamers are gonna start searching around now.
We know Naughty Dog is working on a new Uncharted effort for the PS4 but thus far, we have no details. Where the heck are those hints…?
