Halo 5: Guardians developer 343 Industries has announced a long list of changes coming to the multiplayer game based on feedback received during the recent beta.

"Over the course of the three week beta we saw nearly 20 million games played, accounting for 290 years of collective game time," said Josh Holmes on the Halo Waypoint.

"We provided a true ‘working’ beta that was a snapshot of our game in development. Halo 5: Guardians represents one of the most substantial evolutions of core combat in franchise history.

"We felt it was crucial to get it in the hands of fans early to ensure we have enough development time to react to key learnings and deliver the best possible game when we release later this year."
