is this not done yet?
No, k the only combat features in right now are 1v1 duels with longswords, and archery. I’d imagine we won’t see other weapons for a while.
Yes, I think that too @SirWarriant
With all due respect to the devs, I don’t believe they will manage to release a complete game by the summer 2016 deadline. So many things to invent, implement and adjust. My guess will be summer 2017.
I think you are wrong. The game will be released next year.
But certainly not every single promised feature will be implemented.
People always seem to forget that there is curtain in which many things cannot be seen. The game is farther along then we have access too.
@ProkyBrambora and @McWonderBeast, you both are true 
There is much more gameplay finished than it can be seen in the alpha. Most of the features are not developed in the same build, they had to be put together in the alpha like parts of Lego pieces.
And @ProkyBrambora has a good point, we will not be able to put every feature in the game by summer 2016, some of the not so important features would be addet later.
Everyone who knows a little bit more about Kingdom Come, and how this game was born knows that its a kind of process. Thats why we had to split the game in Acts in the first place. It was not possible to develop the whole game of our dreams at once, and we should not try this, because we are humans and no magicians. Some of the features had to be added later, but they will be added! We want to make this game as we think it should be done, and we will.
We will not stop working on this game, even after release in summer 2016. So stay tuned 
I think it’s better to wait and see.
Devs have my utmost respect, I just want to state my honest, objective opinion.
