Armor lock is one of the many abilities
Halo still manages to make a feeling of community. You still have those people who can forge any map into anything. You have the MLG people. You have the people who are sucked into the lore of the campaign and the books. You have those who play custom games with their friends. You have those you talk smack to. You have those who just play online for the heck of it. You have those who have mastered teamwork through firefight. You have another Halo experience. That is what Halo to me boils down to. The interaction with those people who love the game like I do. I have made friends through this game and met some amazing people who I still talk to today.
So what brings people together in Halo? The answer is simple, Bungie defined the FPS genre how it is today and how we interact with each other in-game. I bet if it weren't for Halo we would just be getting into having headsets and being able to talk to our team mates or our enemies. So what does separate Halo from CoD or any other shooter? Bungie.net is the key here. They have an active forum, you can check any stats and if you see a file you want from work, you can just add it for download later.
