TimeSplitters: Future Perfect Cheats

in the 2nd level (scotland the brave i think) there will be telescope room where you can look at other rooms (considering you havent blown up the cameras that is) in the 2nd telescope room there will be some stairs reach the top of the stairs and look outside with a sniper rifle look towards the way you came from and you should see yourself walking towards the castle, try to shoot yourself in a time paradox :)

In the final level, "Future Perfect". After you defect Splitter Crow he falls down and says "Rosebud". Just as Cain did in the begining and end of the movie.

Beating the boss in Mansion of Madness involves simply side-stepping in
one direction while aiming up and turning. The closer Cortez is to the
fountain, the greater the chance it is to avoid being swiped. When the
boss is about to die, step back and fire the last shots to avoid the
final death blow.

Beating the boss in What Lies Beneath involves simply using the Ghost
Gun and knowing where to stand. Locate a rock that shields Cortez's legs
while allowing him to fire back unimpeded. The fire attack from the boss
has to drop to the floor before moving forward; this simple rock
protects the player from most of the fire breath damage. A melee attack
will destroy the bats and allow the Ghost Gun to damage the tank.

Story levels "Machine Wars" and "Something to Crow About" play similar to "Robot Factory" in TimeSplitters 2, considering that you fight robots similar in ability to ChassisBots and SentryBots. Also, you get involved in taking out energy sources, much like the energy nodes in "Robot Factory".
