You already made a thread, asking something vaguely along these already incredibly vague lines here
http://halocustoms.com/threads/im-new.19890/.
The fact that you didn't get a satisfactory answer in that thread was due to the incredible vagueness of your question. Be more specific, and do it back in the original thread. Don't make even more threads asking the same vague question - people tend to frown on that sort of thing.
The Halo games are played using the "Halo: Master Chief Collection" (Halo:MCC for short) game on the "Xbox One" games console.
Click this link to see what the Halo:MCC game is, and
click this link to see what an Xbox One console is. Please be aware that the Age Rating for this game is 17 - if you are not 17 years old, or older, then you probably shouldn't be playing the Halo games.
If this didn't answer your question, then please be more specific.
