Epic worked long and hard to bring a true cross-platform experience to Fortnite, and they finally hit their goal earlier this year. A ton of work went into the initiative, but somehow they pulled it off. Now they want to take the tools they've developed and spread them to other devs/pubs for the low, low cost of zero dollars.
Successfully launching and operating a live, online game requires a suite of services that go far beyond the functionality of a traditional game engine. These services are expensive to build, test and harden in real-world conditions, but once operational, are relatively inexpensive to scale to more games and more users.
At Epic, our goal is to help game developers succeed. Throughout 2019, we’ll be launching a large set of cross-platform game services originally built for Fortnite, and battle-tested with 200,000,000 players across 7 platforms. These services will be free for all developers, and will be open to all engines, all platforms, and all stores. As a developer, you’re free to choose mix-and-match solutions from Epic and others as you wish.
This means devs/pubs for other games will have access to toolsets that allow for parties, matchmaking, voice chat, and so much more. Check out the full announcement here.
