CARY – Epic Games unveiled major upgrades to its increasingly popular, free-to-play zombie game “Fortnite” on Thursday and is acknowledging that the game’s success is impacting another Epic product “Paragon.”

“By far the biggest change is a complete map revamp, which adds new areas and makes cosmetic changes to existing ones,” Forbes reports about the updates made today.

“We’re getting a new city with room for close-quarters gameplay with plenty of verticalities, as well as an underground mine section along with a number of smaller points of interest scattered across areas players were avoiding before. ”

Regarding Paragon, Epic noted the changes involving that game online.

“We know you have a lot of questions about the future of Paragon. We care deeply about this community and we know this is important to you, so here’s a summary of where we are,” an Epic Community Manager wrote in an online post.

“However, progress has been slower lately for two reasons: First, the team’s time is split between immediate improvements and longer-term efforts, so there’s less visible progress. Second, a number of Paragon team members jumped onto Fortnite to help sustain the game as it has grown far larger than anything in Epic’s past.”

Fortnite, meanwhile, continues to bring in big numbers of players:

It already has attracted more than 45 million players.

And last weekend, Fortnite drew as many as 2 million concurrent players.

“The battle royale game has unsurprisingly drawn comparisons to last-year’s breakout game, PlayerUnknown’s Battlegrounds and is now finding the numbers to match,” notes the UK’s MailOnline. “Still, it has a way to go as PUBG reached 3million concurrent players last year.”
