Yeah....Going off of escapists 5 star system, I'd give it 2 and a half (Don't hate me entirely, I'm basing this purely off of single and multiplayer being taken as equal halves of the entire purchase. Which of course they aren't sadly). Let me tell you why.
The very first time I started up the single player campaign I ran into a glitch during the first firefight. Now I'm embarrassed to admit it did take me a little bit of time to realize what was actually happening (it's been some time since I've played a health-regenerating FPS so this was my fault); My health didn't regenerate. I made it past the first firefight, out into the more open area looking at a consistently black/white environment without really thinking about it. I of course died, then got stuck in a loop of respawning with 2 HP. I could not advance very far.
However, I did eventually get to the point where you ride the elevator. How did I get to this part you may wonder? Well persistence and the game bugging out yet a second time. Yet in a slightly more helpful way. After you get into the open area you can have the helicopter attack enemies as well (and unlike your squadmates they actually do a darn good job). For some reason, it glitched one of the spawns and instantly, before I could even move, started attacking enemies that spawned over the hill. Any enemy that spawned it would just immediately attack them leaving most of the way infront of me barren as I was confused where any of them went.. When you get to the tower the helicopter leaves so I had to brute force my way through that segment with 2 hp.
When you go up the elevator, you fall a little and have to run for a scripted sequence of "run while you get shot by a helicopter". The problem is, due to my low health I would instantly die. The furthest I made it was to the stairs at the end of the start point and that was nothing but pure luck as I typically didn't make it half way. After trying that 15-20 times I finally gave up. Keep in mind I did try restarting the chapter etc during this but it didn't fix the bugs...
So, needless to say I'm not impressed with the games campaign... But wait there's more!
I did eventually try again and it did work. However, through the entire game I saw other bugs/glitches. Nothing major but a lot of them were graphical glitches. This includes floating guns that were grabbed by NPC's during the cutscenes. My assumption was they weren't supposed to be in-shot during the pick-up. I saw dead bodies just floating there in the background during cutscenes. I have a somewhat poor quality of one of these instances as it reminded me a bit of slenderman and amused me.
I don't really want to type much more than I have already but, yeah...it's really bad. I'm not even going to discuss the plot, characters, and everything else because that isn't that great or even coherent.
As for multiplayer? It's OK. It's just another battlefield game. Nothing to get excited about. The multiplayer has quite a few issues with it right now actually. Some that don't let people play, some that are annoying, and a few that are just slightly bothersome.
I'm not fond of saying this, but come on guys...you can hire people to QA your stuff pretty cheap. I found so much without trying that I'm embarrassed that this is a classified as a "AAA Title".
I'd like to add it's just come to my attention that, while I appear to keep the couple unlocks I managed to get (for the time being), my campaign's save doesn't appear to be there. Meaning I now need to play everything all over again, including getting the collectibles (as I didn't obtain them all in the first few chapters, nor did i beat all the scores)for achievements/more unlocks. That's 100% unacceptable for reasons that should be obvious.
I was being civil prior, but now I can say this game is not worth anyone's time unless you're a hardcore battlefield player.Though you could just stick with BF3 ...but oh well. If you're on the xbox anyway. I heard PC was having issues too but I didn't look into it (and im sure there's an article on the escapist somewhere..maybe..if you're curious).
