Knife duel (QTE)
Fast sequences with a mid-point checkpoint. Keep your hands on the controller through the entire cutscene — more people die here than to any boss.
Walkthrough
Laser corridor: advance when the beams rise / go vertical; the last ones are QTEs. Boss U-3 “It”: in the containers it can’t die — shoot the green buttons and dodge; in its lair use red barrels and the door trap (drops 50,000pts). Blue Stone of Treason in the camp tunnel → full Golden Lynx, 35,000pts. One last shooting gallery.
Boss — Jack Krauser
Collect the 3 pieces (Panther NE · Eagle W tower · Serpent, which he drops himself). In the tower, a 3-minute timer: shoot only his legs (the mutated arm blocks the torso) and finish with a magnum to the head — or pure knife, which deals absurd damage to him. Drops the final piece.
