I like cod4 for multiplayer matches but the zomies on cod5 co-op is great fun. I did complete both games on story mode and cod4 was great fun on that aswell
id have to say cod5. the nazi zombies is awesome,the extra maps r even mor eownage, and the campaign is ok. favorite missions r prob the jap sabotage mission and 'burn em out'. god it is fun to burn the banzai alive! or maybe im just a disturbed kid =D
They both have good and bad cod5 has terrible spawn but great levels cod 4 has the weapons that rock but sometimes its not even a challenge to kill someone
I think I like COD5 better because since most of the guns are not rapid fire it makes it more challenging and also can't forgot the zombies but I like how Cod4 is modern and has cool guns
