The video and music are just cuz it looks nice and shit. You roleplay in this community by commenting on roleplay posts and that's pretty much it. But it is very fun, so if you like Halo and Roleplaying be sure to check the community out!

(Note that there are reasons that this community is canon strict, it wouldn't be as good as it is if we let people do whatever they want, be sure to check the rules out. Thanks.)
Video: From different Halo Games. Music: We Are - Hollywood Undead.
Thanks for watching.
