When we first heard of BF4, we all wondered at first what was going to be new? To start off, BF4 is going to be run off of the new Frostbite 3 engine. Which we all know means, better graphics, better game play, ect. Another thing that got people's attention was the "Commander mode" in which a player has control of various missiles and can command the players on his or her team. More recently the BF4 team said that there will be more thing to "Blow up" and change the way one might capture an area. One of these things I'm very excited about is the road blocks that you can activate, which block the path for tanks. One thing i do wonder about this is, if the tan is on top of the barrier when it's activated, will the tank blow up? Oh and don't forget about the sky scraper in Dow n town Hong Kong falling over. Now that they are introducing "Theater mode" into BF4 making Lets plays and reviews is going to be so much easier now. I hope theater mode is going to be included in Campaign, like Halo.
Given all this, BF4 should be a great upgrade from BF3, but the one thing that take all the realism of the Battlefield series, is the introduction of kill cams. This is not something that should be in BF4. What i loved about the Battlefield series what that i could hide and snipe with out and anyone finding me from the kill cams. I really do hope they take that out before release day.
