Though a third entry in the Just Cause series remains unannounced, the evidence of its existence continues to mount. The latest findings come in the form of four alleged screenshots taken from the Xbox One version of the game, which surfaced in the Xbox-Underground forums recently.

The images appear to show main character Rico, and an overview of what looks like an island. The screenshot above also seems to suggest that the game might have microtransactions in some form--not an uncommon thing for major games today.

A source reportedly close to the game verified to Eurogamer that the image above is indeed from Just Cause 3, explaining that it shows off the game's "Black Market." The source went on to claim that, at one time, the PC version was planned to be entirely free-to-play while the console versions would be paid games supported by microtransactions.

However, Eurogamer says "the plan changed and this may no longer be the case."

Representatives for Just Cause developer Avalanche Studios and publisher Square Enix declined to comment when approached by Eurogamer.

Avalanche boss Christofer Sundberg said previously that microtransactions are simply part of the new generation of games, though he wants to make sure gamers are treated fairly.

"Microtransactions, subscriptions, and other biz models will be the next generation of games. It is that simple," he said on Twitter last year. He later expanded on the thought, stating that "greed never works."

"We'll never compromise on quality or sell our souls for a quick buck," Sundberg added. "Things are changing and we need to adapt."

The announcement of a third Just Cause game would come as little surprise. After all, Square Enix registered a Just Cause 3 domain name earlier this year. Avalanche has also previously released some blurry teaser images of what appeared to be a new Just Cause game last February.

Avalanche is also developing a Mad Max game based on the movie series that was recently delayed to 2015, and a game based on a comic book series that isn't Superman.
