Aside from the lame and limited gameplay, the real point of frustration for me was the poor/limited thought given by the designers to making the game enjoyable and aggravation-free. Case in point: when you die fighting the first crab-creature (which you will), you are forced to sit through the minute-plus cinematic all over again. What idiot thought this was a good idea, as opposed to re-starting the battle right at the moment it begins? The same thing happens later when you encounter another crab-creature in a cavern. When you die (which you will) you're taken back to the entrance to the cavern where you have to walk for a full minute just to start the battle scene all over again. Idiotic! And frustrating!! Don't waste my time! It was at this point that I ejected the disc and mailed it back in.
Additionally, the HUD screen text is too small to read easily, even on my 70" screen, and is often impossible to read against the background, depending upon where you're standing. Aiming the weapons is frustratingly difficult. First-person is SOOO much easier for shooters.
Aside from all of these poor design elements, there is limited gameplay outside the main story line, making this a very unsatisfying game to play. Thumbs down, and whoever ultimately signed off on releasing this game without putting it through solid QA testing should be demoted.
Same combat mechanics as earlier games which I like, but now there's way too much talking to people, walking around, and waiting for storyline stuff to play out. I much prefer just picking a level and jumping straight into the action from there. Movies are for watching, games are for playing.
