Let's be honest, for me you are "VERY" kind with what is in this EA.
To me it is not a beta, probably not even an alpha, i would say a pre-alpha, there is litteraly hundreds of fix/enhancements to be made, we lack more than half of the game and all the balancing pass on pretty much everything "weapons, classes, talents, mobs, environement, et cetera..." Which obviously cannot be done because this is the last thing you do.
Maps are underwhelming too, they have no "soul", if you don't see what i mean you are either a fanboy or blind or unaware of what is missing.
I'm not commenting the lack of communication because i know how other companies can be (ex blizzard), ****ting on their customers mouth when D3 was released, or the stupid moves they are doing in WoD.
All in all, I am extremly disapointed so far.
I love the fact that no matter what game, there are always complainers. I was actually very impressed with how this first came out. I expect problems, and lack of content when I purchase an early access title. Most of the ones I have tried started out much worse than KF2 did. There was very little to actually do and 90% of the game was unfinished.
KF2 comes out with 3 maps and around half of the total perks that will be available. Not only that but the level system for those perks is already in place and you even have access to one of the bosses.
Also, it is fairly bug free currently. I have had no major issues with the game at all.
The fact is that you simply are complaining because more of the game isnt playable yet. Not because it is unplayable or riddled with bugs.
It seems to me that TWI is taking a very good approach with this so far. They add features, (maps and perks for example) only when they are mostly complete. I am guessing these perks were the first ones they worked on and are therefore the first ones that reached an almost finished state.
I much prefer playing with limited, but functional features than playing a game that has all of the features and only a couple of them work.
