What a game. It's a classic FPS, blended with a roguelike, meets Portal, with some bullet hell thrown in. Graphics are great and run on a wide range of low to medium end laptops. It really shines on a moderately to high powered rig, though. Not much storyline to it, but it doesn't need it/ It's the most fun I've had with a shooter in a while, 3D or otherwise.
The Journeyman Trilogy concludes in this game. This is the full, DVD-ripped version of the game with (pseudo) high quality movies. It's awesome that GOG got this working with Win7/8 with no legacy issues. If you like first person adventures, do yourself a favor and get this... it's up there with the best of them!
