The story line is interesting and complex, although you shouldnt give it too much thought as it is somewhat weak. The ending was interesting and engaging. You are offered some options throughout the game but the outcomes are not as exciting as they could have been. The WASD with mouselook control was effective and accurate when fighting. I have an issue with the fact that I cannot create my own savegame, that they are all savepoints in the game. If I missed an area after going into the next area, I could not go back to look for items or supplies which left me wondering if I had screwed myself on a critical upgrade. The weapons were fun, but average. The new twist is your time weapon on your hand. It was used as a vehicle for the plot line and did some pretty cool things. Overall I like the game quite a bit but it was too short. It also gave you no reason whatsoever to play the game over again. No perks, no starting a new game with previous upgrades, no unlocks, etc. To me that makes a game worth buying. If I were you I would wait till this game comes down $20.
