By now, you've either bought into the latest Call of Duty craze, or hated it which splits the community by a considerable amount.
The third side are from the people who look at this game objectively and can literally see the faults that lie within.
From over 100 hours of gameplay, I've finally zero'd in on the glaring issues that Treyarch can either fix, or ones that are just part of the game's structure and design. Naturally, going over each and every point would prove time consuming and uninteresting to some. So, to sum up the entire game, Black ops II runs on anomalies.
This means that the way the game performs at some stages are unpredicted and cannot be helped. They are not in the hands of the developers, they are simply part of the game. The first subject I'll start with is campers. We all hate them. They plague every FPS, and Call of Duty is the mini-van that they all stay in. If anyone's played Call of Duty 4, you'll know that campers were annoying, however the game was designed in such a way that they were easy to deal with. Constant UAV's in the air makes it easy to spot them, since Stopping Power ruled the game. Plus, with the lack of attachments, players leaned towards naked guns instead of using silencers. This makes the game a lot faster, since sprinting round and killing a camper not only gives you satisfaction, but keeps the game moving which is the crucial point. Keeping the flow.
Treyarch and Black Ops II threw it out the window.
The constant stream of UAV's is gone, since it takes literally 5 kills to get one. This means campers have a much easier time sitting in corners and picking off players who want to run & gun. Along with that, with the abundance of Stopping Power, Ghost rules the day once more. This makes going for high score streaks literally unrealistic, which is the worst possible trait to have in a game. Something that escapes you from reality having something that's unrealistic? It's like having a dream and being told you can't fly.
I'll keep it short, so only one more point which is the one Treyarch themselves messed up on. The spawns. Yet again, I take you back to Call of Duty 4, arguably the best in the series. Spawns were not a problem. No-one noticed them, which is how they need to be. Someone spawns, and that's that. They should have their own space for at least 5-10 seconds. Yet again, Treyarch didn't design the game to the lowest standard, and the spawns are the biggest anomaly and issue in the entire game. You literally spawn and within a second or faster, you're vulnerable to anyone. (Just play Free-for-all on Carrier if you want a good example.) I don't understand what was going through Treyarch's mind when they designed this mechanic. Of course, I'm no-one to talk. I know little to the aspects of implementing these mechanics in reality. But taking the time to plan and sort one of the most key concepts of the game should be a top priority.
In conclusion, Black Ops II is a mess. It always will be. They tried to make a different sort of FPS, but that's not what Call of Duty is. I buy CoD for CoD. I don't buy CoD for an FPS I can get from any other title. There isn't any skill involved anymore, like there was in CoD 4. You can't jump round corners with your sights and hope to see an enemy or two, because one will just come from behind you. You can't storm in to a building guns blazing, because a camper will kill you. You can't think out a proper route in Seach & Destroy, because they'll come from behind you.
The final word of Treyarch: No Fun Allowed.
