It's pretty much right there in the title of the video... 12 minutes of overview for Halo Infinite's multiplayer.
A lot of folks have that one shooter that just opened up the FPS genre for them. For some other old hats like me it might be classic Doom or Quake or Unreal Tournament. For the younger gamers maybe it was a Battlefield or Call of Duty. For me, it was LAN parties playing Halo. Before then, I was a hard-core JRPG and EA sports guy. Afterwards? Combat Evolved? Oh heck yes.
The video, while interspersed with some action footage, does a great job of detailing the theory and thought behind the multiplayer experience in the latest iteration of the franchise. If I were to sum it up I'd say they are trying to capture that look and feel of the classic game we know and love, while also providing a few tweaks to keep it relevant in today's very crowded field of FPS games. Also there are some great customizations incoming to keep it personal and the video gives some detail on how the free to play aspect will work in relation to the cosmetic upgrades available in the for pay Battle Passes.
After delays Halo Infinite is scheduled to release sometime in late 2021 for Xbox One, Xbox Series X|S, and PC.
