My first real Halo experience was playing Halo Reach with my little brother. My mom asked if I thought he’d like it as a present, and I said it seemed like it was a popular franchise. Course, I never had played it before but it had Co Op so we played together, I ended up getting fixated and then finished campaign too. XD I played it so much I had to buy it 3 times. It also has awesome enemy sangheili, and they became my favorite alien race. Ai and design, pretty solid. Modding Reach is fun too!
2 for campaign, Infinite for multiplayer.
2’s campaign expanded the scope of the Halo universe so significantly and was not afraid to try new things
Infinite’s MP is just so solid, customization and BP stuff aside, it is very well balanced, maps are great, and incredible forge maps are finally making their way to matchmaking.
