It came out okay-ish, no real game-breaking bugs, after patches it is even better.

I have played since launch and only had one CTD, one face not work during a conversation,and some stuttering when moving in range of a complex.

Everything else has been on par with a stalker game. Good atmosphere, constant threat of death, not enough ammo, and random stuttering.

Fantastic game IMO. Been playing since launch even with its quirks it has been a very enjoyable experience.

Playable I'd say, especially now that they seem to have fixed the crazy spawn issue that dumped mobs on you almost constantly.

Ai is not the best. Nevermind A-life, sometimes during a firefight Id go to reload in a room when I come back out they've all forgotten about me and aiming away from me.

Sometimes I have to shoot warning shots just so I can enjoy a fight.

That and the optimisation, other than those it's a fine game. It's gonna be great when they fix it.
