The game doesn't seem to have any sliders for brightness, gamma etc. among its graphics options. Is it possible to adjust those settings via ini tweaks or anything like that?

For some reason the full version of the game looks darker to me than the demo did. Any convenient / practical way to adjust this?

Thanks for the response! I just tested it, but it only seems to affect the dark tones/shadows. I mostly wanted to increase the brightness of the lighter tones, such as the snow. Even with the slider at max, the snow still looks dull and grey. Did you guys add some kind of filter to reduce contrast? I guess it's no big deal, just looked a little odd to me, especially in those lighter ( snow covered ) missions. If it really is some kind of filter or post-processing effect, it would be nice if you guys could add an option to turn it off, or reduce its opacity.

While you're around, how many missions does the game currently have? And are there any plans for future expansions or mission DLCs? Overall the game has been really good so far.

I'm throwing myself here too, as I'd like to know about the possible DLC plans. I think I might be nearing the end of the game soon and while I normally don't care for DLC, with this game I'd be happy to know if we'd get more of it in the future. This game is just that good.
