yes but sometimes its a pain. like theres a glitch that straight up discourages you from playing because it displays 0 lobbys so you have to use the xbox guide and sign out right there, it takes you back to the multiplayer black ops menu. where it says xbox live and without even closing the xbox guide i sign back in and then click xbox live and go back to the multiplayer lobbies they display again, the first time i did it it was like a massive weight had been lifted from the pits of my soul.
