Uncertainty still surrounds the PS Plus June 2016 lineup, though some clues from earlier this year may be hinting at the games that could be included in next month's collection of free titles.

Back in April, a screenshot that seemed to include some PS Plus titles made its way online and it indicated that both "Watch Dogs" and "Tetris Ultimate" could soon be made available for free to the service's subscribers.

The screenshot was also shared over on Reddit and it seemed to indicate that the aforementioned titles may be offered to players as part of the service for the month of May, though that didn't end up happening.

Still, there's a chance that the games featured in the screenshot may end up being part of the PS Plus lineup anyway.

Recently, "Watch Dogs 2" has become a topic of conversation among gamers after Ubisoft CEO Yves Guillemot talked about the game briefly during an earnings call. Recent chatter surrounding the sequel has even begun to indicate that it may make an appearance at E3, though that has not been confirmed.

If Ubisoft truly wants to get people talking about "Watch Dogs 2," then one way to do so may be through making its predecessor available via the PS Plus service, as ThisGenGaming suggested.

With "Tetris Ultimate" also being a Ubisoft-published title, the company may also decide to sign off on it being included in the PS Plus June 2016 lineup just to create even more buzz.

As for other non-Ubisoft titles that may be included in next month's lineup, ThisGenGaming also suggests that the unique adventure game "Everybody's Gone to the Rapture" could be a potential offering.

The good news is that with only a few days left in May, subscribers will know more about the official list of PS Plus June 2016 games very soon, and hopefully, there will be some quality titles included.
