lol. The games are so very different, even with the many things Halo has drawn from Cod, they are still worlds apart. Anybody who's actually played both games can tell you that. You're friend is either ignorant or stupid.
See what I hate is that people complain that it took things from cod.
But in actuality they've taken things from each other. Halo brought a lot to the table and so many games have taken tips and actual parts and placed it into their games --- Gamertag: Zerochronic R.I.P Mom..Aug 30th, 2007
