Bungie is confident shared-world shooter Destiny will run smoothly at launch.

We've seen some high profile games suffer at launch in recent years for a variety of reasons: Blizzard's Diablo 3 and EA's SimCity and Battlefield 4 to name but a few.

So you'd be forgiven for worrying that Destiny, an always online game, might suffer similar issues at launch when the horde descends upon its servers this September.

But Bungie has been plotting and planning and preparing for launch for some time, the studio told Eurogamer sister site GamesIndustry International. Indeed the recent Destiny alpha was in part a test of the infrastructure powering the game.

"We have been actively preparing," Bungie COO Pete Parsons said.

"It's always scary and exciting and to put your work out in front of people who are judging it but it's also scary to put it out there because you're testing whether it's going to work or not."

Bungie has been testing Destiny for months now, Parsons said. It launched a friends and family alpha some eight weeks ago, and then the alpha was opened up to PlayStation 4 owners over E3 week earlier this month. A beta is expected next month.

Destiny is published by Activision, whose Demonware online software and services company has also chipped in to help.

"They've really learned a lot over the last year, so we take it super seriously and we've been planning for a long time," Parsons said.

"We've been investing to make sure that we have the best experience possible.

"We will ultimately see what happens but we have every expectation of from moment one having a great experience."

The proof will be in the pudding when Destiny launches in September 2014 on PlayStation 4, Xbox One, PlayStation 3 and Xbox 360.
