At the end of 2015, "Fallout 4" director Todd Howard hinted updates for the game in 2016.

Naturally, many fans are anticipating and nosing around. So far, there are several leaks and rumors on what "Fallout 4" DLC updates will be all about.

Buzz surfaced that the game will feature underwater challenges. As noted by Kotaku in December last year, the "Fallout 4" map is hugely comprised of water -- an indication of the game's possible location

With fragments leading to the possibility of existence of underwater wonders, Javon Smith was lured into playing for over 30 hours in search of clues.

He found nothing interesting, but that doesn't end the search.

The underwater world is a popular topic, but  some fans are also voicing out their other requests for "Fallout 4's" DLC update.

While many love aquatic adventures, others are rooting for a cosmic exploration. Rumor has it that the moon will be among the game's new location.

Moreover, other fans are wanting to dig deep into the characters. A gamer suggested that the game should reveal more about Conrad Kellogg's past. News outlet Inverse suggests that "Fallout 4's" DLC update feature the humble life of the mercenary and his journey to fame before his demise, reports Christian Today.

While Bethesda Game Studios will most like take into account fan requests as they develop updates for the open-world action role playing videogame, nothing is officially confirmed so we might have to wait a little longer, reports Christian Post.
