This is a wonderful game.. actually it's an incredible game, here's why.

First off, the genuine quality of the game, as in the amount of bugs and errors are very little, and any at all barely even effect the game, actually one bug is on some custom maps Zeds get stuck, so that's mildy annoying, but is overwhelmed by the positves. The game is also very well polished, clean, and mechanics work well.

Another positive aspect I quite like, is the perk levelling system, it's quite an improvment over the first game, as it doesn't take weeks to get to top levels (not that i'd mind too much), which allows people to experience the games different difficulty levels and to try and become better at the game, and extending that time too with prestiging that allows people to learn how to play a perk at whatever level they are at effectively and any difficulty. Leading on to my next point about difficulty. The different levels of difficulty are quite nice, as you've got the normal mode, for people who recently got the game, or if you want to try out a low level perk with other players, then you got hard for general players who are decent at the game and then Suicidal and Hell On Earth, which I personally have difficulty doing (barely do suicidal on a select amount of maps), but I still love playing these, of course only with other people who are also of a similar skill, cause HoE is as it would be, very very hard. And the difficulty allows you to try different perks to see what you are a good at and what not, thus giving you practice in all perks.

Another incredible positive, is the continual support and updates for the game. Like it's predecessor KF1, the game has had continuous updates since it's intial development and early access, which is common, but what makes it different with KF2, is that it's still being updated, Tripwire still give it the content that we consume for it, I mean, look at KF1, that games was being updated for years, showing that Tripwire care about the games, and what people think about it. So this gives the game not only consistant new content, but also a sense of understanding between the community and the company (most of the time), and props to Tripwire for constant updates to this game whilst also managing another game with the same kind of care.

The bosses too, are all great with how they're done and work in each different scenario, and in some maps they can be more difficult but it's all a new challenge with each one.
I will criticize how the bosses have been added though, as it seems that they've been added with increasing difficulty, which for the most part is fine, especially when the boss is randomized, gives that difficulty change and makes you adapt to the boss, and know how to take them down and not be taken down.
Except the Matriarch, a boss which is done well and is neat, but is horribly overpowered, having attacks all round that can do huge damage on any difficulty, which is okay since other bosses can do that if you're not careful, but what is the issue, is you can get a few hits on her before losing half your health or dying, if not by her instead one of the E.D.A.Rs, which would be okay, if they didn't do huge damage in numbers while you still need to run away from the Matriarch which is the worst fault for this boss. Every other boss is fine, maybe King Fleshpound might need to be tweaked for Berserkers, but the Matriarch certainly needs fixing.

The graphics too have an issue. Now I don't mean the entire graphics, but, I do mean the lack of support for Integrated GPUs (meaning the CPU is running the Graphics), as there are a heap of people (don't know what percentage of players) that are running off of a laptop, that have to deal with parts of maps, or in some cases, the entire map, being completely pitch black, with no possible way of playing effectively.

Update Edit
I love the newer weapons, as much as I dislike that a lot are DLC, it is what it is, games need to make money.
They're all nice and all, but the ones that I particularly like are the HZ12, Rhino, Ion Thruster, and the new (to date) Piranhas, Tommy Boom, Corruptor and HRG Bastion .
The HZ12 is a really good Support shotty, being either a double or single shot and being magazine fed, a good primary shotty. The Rhinos I like due to being small shotguns with ricochet which is nice even when being a little inaccurate, and they look cool. Ion Thruster, I love, with the right perk abilities you can mow down waves with it alone. The Piranhas are really good as a backup and large zed killer for 'zerker. The Tommy Boom, is, insane, with a level 25 Demolitionist, it quite literally becomes a small, handheld autocannon eliminating everything. The Corruptor is a really nice bolt-action rifle, like the centrefire but more powerful, and a bonus poison effect. The Bastion, is like the Minigun, only in a small package and faster to boot, a laser of bullets.
Not a favourite, but the Glock 18 and shield combo are great, nice high rate of fire, and an uncommon parry defense for a non melee weapon.
As for other weapons, seal squeal and other HRGs, they're okay, nothing too special from my use of them.

So all in all, a very well polished game that runs well on most computers. I'll give it 9 outta 10.

As for what happened to the now ex-CEO John Gib\son, I'm glad they removed him quickly, as when you say something on the internet where everyone can see, then you've made that everyone elses problem too.
