Peak's Peak. The story is outstanding, so much so that one of my friends couldn't even play the other games because of how good it was. The gameplay is a little out there with spartan abilities but it's still overall great. Firefight is back form ODST and is expanded upon. Invasion is a good game mode. The customization is fantastic. Everything is top notch. Bungie really put their all into their final halo game and it shows. This game was so much fun back in the day and I'm grateful that it exists
