A decent shooter in the vein of Half-Life, but without the improvements you would expect given the ten year difference between them. The main plot device had so much potential, yet they underutilize it - imagine if in Portal, all you ever had to do was use it to cross gaps.

Exploration is also non-existent, as you cannot leave the intended path - even jumps that look doable are blocked by invisible walls. Health, Ammo and Upgrade Materials are abundant, at least on Normal difficulty, so no big challenge.

I put this game off for years due to concerns about the horror elements, but those did not expand beyond one hand trying to grab you through a door, and one dead body as you turn around a corner (where the "be afraid!"-audio cue is scarier than the sight itself).
