Really enjoying it. Yes it has the 'indie' feel, can't really put my finger on why though.
The game is really fun. Only got until the second proper stage (EVE or whatever). Already restarted my Character.
First guy was melee focused, well I though he was, but I didn't invest into the correct skills. I found hacking terribly hard with the first guy and because I didn't invest into the correct skills, my assumed melee profession lead the game to be extremely hard
(Hell I had to sneak on top of structures, waiting for the guy to turn away, leap down on him hand his ass to him and then get back into the shadows, or I get killed like a boss).
So restarted, invested heavily into hacking and guns. Now I kinda just hack my way through the game. On the first level I had like 4 looters just running around killing their brethren. Also turned the sentries against their owners. Hell I have yet to kill a single person myself hah.
As someone else said, the game really feels deep. Can't confirm if it's just on face value, but at this stage, playing as two separate builds, it was a completely different experience.
I love the soundtrack! it really fits so well with the bleak feel. Saw that its up for download, so gonna grab it.
Have not tried MP/ Co-op yet. But it should be really fun! Especially if you diversify the skill sets offered.
And now for some tips with hacking:
What I found so far, to be the easiest way to hack is start by mask, then hit overflow, then attack. Repeat.
The train of thought is like this: You take down their attack value (mask). They try to counter it by increasing theirs. You then increase your attack value (overflow). They then try to counter you by taking yours down. And then you attack.
What this leads to is a game of chase, which you win, thanks to having a quicker 'hacking gauge' or whatever its called. The nice thing here is that the only value you have to worry about is your own Cyber HP.
