Unity is developing an array of new multiplayer tools and services for developers using its game engine.
The first phase of the new UNET project will include features such as a high performance transport layer based on UDP to support all game types, a matchmaker service and a relay server to help solve connectivity problems.
The new multiplayer tools will be introduced when Unity 5 is released later this year.

Unity’s announcement comes as indie developers have aired mixed opinions on whether multiplayer games are viable for small teams.

In a recent interview with Develop however, Freejam revealed their multiplayer-focused game Robocraft had garnered 300,000 players, and discussed ways indies can make multiplayer titles a success.
