Alright. This is going to be a long one. But my true feelings on the multiplayer aspect of the game.
I played Killzone 2 and 3 extensively, and enjoyed and played 2 more than 3, but still enjoyed both, due to me enjoying the handling, weapons, universe, etc.
What I like about this game: They got rid of the stupid bullshit. No mechs, to imbalance games. No jetpacks. The class where you could have gone invisible with the best fully automatic gun in Killzone 3 (Scout, with sTA 52 rifle) is now fair, given only 3 sniper rifles, the shittiest weapon in possibly the whole game ( triple burst spoor is useless, Dreams-Visions is 100 correct) and can only go cloaked with a knife.
The classes are brilliant! Assault makes sense. The point is to go in with it. Therefore, it has, without a doubt, the 2 best weapons in the game (Rumblr and Keyser), and aggressive perks, with the option of assault buddy bot, speed boost, etc and the mandatory shield option, which is deadly if you use it well.
Support is Medic, Tactician, and Engineer all crammed beautifully into one. The weapons, such as its shotgun, LMG, and rifle are all very good and can stand up to the 2 better weapons, and its other 2 "wildcard weapons" ( minigun, and petrustite 3 burst thing) can be effective, but I do not see them being used in competitive clan battles. This game really makes you think? Damn, they need my spawn beacon, no one else is running it. Damn, a base bot would be great here! Wow, an Airbot would really get me kills! Very balanced, and your class decision really impacts the game and your performance. Great job on the classes, Guerilla Games.
One thing that bugs me as I said before is that my favorite gun, spoor, is terrible. But If I had to guess, Guerilla didn't want to make the mistake of giving the "cheese" class of Killzone 3 a fully auto weapon again, and therefore made this SMG near useless. But they still gave us a close encounter option. You aren't winning any gunfights with it though, it could use a buff.
Maps are pretty good! I love that Bilgarsk Boulevard of broken dreams is back. Only one thing that pisses me off though. Give me some indication of where the base and base bots are! In the beginning of learning the game, I got many free deaths just from this lack of knowledge. It is very frustrating and I believe that they should be painted red on your map.
Okay, now to the things that should be fixed:
This is something that has not been fixed since killzone 2 and 3, and why, I'm not sure! One of the lamest things was joining a game late, and seeing the score 0-6. Why is this game still going on? It was over at 0-4. Guerilla, please, or anyone who claims to be getting PM's from devs, include this in your fix list; MAKE THE GAME END WHEN A TEAM SCORES 3 MISSION POINTS. The game should end there. No reason to fight a losing battle.
Mic chat. Already addressed, will definitely get addressed. Right Guerilla?
TRUE PARTY SYSTEM. Please give it to us. Not this "press option button to join friend and if you miss it within 15 seconds too bad nonsense"
Okay, that's my opinion. Overall, I really like this game. I see myself playing until the next Killzone is released, and I feel every PS4 owner should give this mutiplayer a shot.
