According to a post made on its official forum site, a member of Kaos Studio’s Frontlines: Fuel of War development team, who goes under the forum name deslief, stated that “Frontlines will in fact have some servers set to 50 players on the Xbox.” Kaos had actually decided to go as high as 73 players for its Xbox LIVE Frontline servers but had decided to settle on the more comfortable and casual 50 players. It is uncertain as yet how well this unprecedented number will function in the actual product but stick here to TheGameReviews.com [add in link to the game page for frontlines] for more info on this story as we receive it.
