If you have a read at the bf hardline thread ,
you will find a lot of us/players , aren't that impressed with hardline ,
one lad did say to me that it was a lot like COD , which i guess is why you like it ,
as for me , im not that impressed with it at all , i wont be buying HL
As for BF4 , now that is game you may enjoy , , but the play style of the game is completely different to cod , for 1 you have to play in a squad , if not and try to run around like chuck norris
your just going to get killed every ten seconds , and that in turn will put you off the game very very quickly .
but if you work with the squad you can have a good time playing bf4 ,
it's best to talk to your squad and let them know whats going on , and in turn they will do the same with you ,
granted , most random games , you won't be talking to random people , but you will find that squads/teams still play together , ( i have had a good few game with randoms and we/their have still played all together ) but that is how the game works
there is a lot to learn about the game , so if you pick it up ,
pop over to the main bf thread , and pick a few names out ( the one's that post the most are the one's that play it on a regular bases ) and drop them FR ,
as well as me,
jump in a few games and im sure someone will talk you through the basic's .
