A question about the Halo sereies.?

why hasnt halo made AI Bots in multiplayer? that would be great. like the game Night Fire. has the best multi player ever. mabey not the best graphics or anything. but the idea is the best. u can choose what the enemies look like, how good they are, how fast their reaction to u shooting at them is, how good their aim is, how fast they run, how "agressive" they are, how much health they have, and even what they act like. u cna make them so if u kill them they will come and try to find u and kill u, make htem so they kill the weakest person, make them to kill the guy with the most kills, make them ignore all "pick ups" ardoun the map, make them pick up every weapon they see. its awsome. they should make a halo game like that. like Halo Reach. make AI Bots so u can still have fun when ur by urself and u cant go online. like me. i would if i had faster internet. but for those who dont have fast internet or just dont have xbox live, the should have the bots. its a really good idea.
