Jump deftly, throw crates to solve puzzles, use bullets, bombs, swords, missiles and turrets.
Fire a few bullets to stun an enemy, then close in and stab them to death with your sword. Fire a rocket from a distance and blow an enemy off a ledge. Deftly jump from a wall to a collapsing pile of crates to another wall, then drop down in a surprise attack. Use your sword to throw a crate onto a button to release some more crates that will form a platform over which to slide another crate to another button. Blow a door with a perfectly judged throw of a time bomb. Use a portable turret to draw fire and then sneak round the back and clean up.
