Graphics are nice. The level design is nothing visually mind-blowing. The entire game takes place in Egypt so there's a lot of desert and fragments of ruins. Interior levels are a bit of a pain. Visibility is limited. You need to use a flashlight to see anything and finding your way isn't always easy. Levels are very linear. There's zero exploration outside of locating secret items scattered about (often in the corners).
This game is a first-person shooter in it's standard mode, but it's easy to toggle into third-person. I played the entire game in third-person and found it to play extremely well in that mode with the exception of jumping to scale an object. I tried jumping in first-person, however, and it didn't really make any difference.
I liked the story in this game. It's very simplistic. Aliens are everywhere. Sam is on his own as he quests to turn on some crazy weapons known as the "Time Lock." It's not a deep story, but it's not bad for a game that is basically chaos incarnate. Sam is an over-the-top tough guy with a touch of humor, so he's fun enough in the role of narrator.
