Ok. after I figured out my L3 button actually did work this is what I know about PS4 BF4.
I have only played as engineer class because the gun was so shitty in the beta, I'm trying to get past it.
1. Guns kill MW2 fast.. wow.. this is so different for BF, I dont know what to think. You use to have to hold your sight on a target for a good 1.5-3 seconds on a target to drop them and expend a good amount of bullets. I complained when COD went to this method because it was suppose to be fast paced. Either its just SMGs or these franchises have flip flopped... there is still a chance DICE may nerf stuff, but I think it could be a sign of what to expect in Battlefront. I was getting dropped fast by assault rifles so I will say for now. Guns kill wicked fast. If you don't like it, get use to it.
2. The littlebird is fucking deadly.... I was playing with it in test range and its maneuverability is off the charts compared to BF3... Its minigun is way more powerful and accurate... again I think this equates to guns kill faster... that doesn't apply to other vehicles though. It took a good 2-4 cool downs to take out a pratice drone. I need to get this in a real match.
3. This game is beautiful. My TV only runs in 720p, and it looks great.
4. Weapons start out with optics
5. Premium members are treated to battlepacks, you open them one at a time and get a random slew of goodies. They seem to come out every month. I got some gun camos, 1 hour 50% more xp, a new knife, and some emblem options.
6. DICE seemed to forgoe BF3's soldier loadout on the title screen and reverted back to BFBC2 where you have to do it in game.. you can probably do it via battlelog as well, but I haven't checked. I don't like this, but I dont hate it I guess.
7. Even though I've done it for years on COD. having O/B instead of R1 for knife is throwing me off so bad... I guess I wasn't a big melee person in COD, but I was in BF. I've blasted a few snipers from behind just to level up my gun... i passed on dog tags.. lol
8. I acutally like the Sony's control layout better.. mostly because the D pad has always been superior.
9. PS4's triggers are a dream. 360 triggers are awesome, but PS4 really stole from it and found a way to make it "luxurious". The curvature of the buttons just feel right.
