I have watched HALO movies prior to playing the game. So my experience is kind of reverse. Most of the people watch movies later after playing game. I have kind of starting to like this series. Here HALO developers have released Halo: Fireteam Raven. They seems to have found out pretty good combination of graphics and plot with the new released. If you have not checked 2018's release then check out the walkthrough to see if you wish to play it.
