Sure, you've been making multiplayer levels with Halo 5: Guardians' Forge mode, but now Microsoft wants you to create something different for the game. Like a web app or something along those lines for the stats coming from its online gametypes. Last year near Halo 5's launch developer 343 Industries released an API in beta, and now it's added access to "raw match events endpoint" data that the studio says will offer a wealth of info on each kill from any match. That's including, but not limited to, Gamertag of the rival, weapon used in the kill, where it was in terms of the game's play clock and map coordinates for where it went down.
