I just got this game with the Pay 10 Get 5 promo and I have to say I think it's seriously underrated.

I'm really enjoying the puzzles and exploring the environments. Also I get sort of a Myst vibe from the game's atmosphere and sound, which is always welcome.

All in all great game. Anyone else get this in the promo and was pleasantly surprised?

Played it ages ago, when it was still a free a mod for UT3. Liked it back then, though I can't remember if I finished it. Got the standalone game in the promo, but haven't tried it yet.

The problem is that the first few hours are great but after that it's just the same damn thing over and over and over again for 6-8 hours. The game simply needs more variety to be good. But for that low prize you can play it for a few hours and then uninstall it and still get your money's worth.
