Let's play : Wing Commander 3 :Heart of the Tiger - Live stream Part # 1
The Victory is assigned to the Orsini System, away from the front. Shortly after Blair's arrival, test pilot Major Jace "Flash" Dillon arrives on board the Victory with his prototype warcraft, the F-103A Excalibur heavy fighter. When Flash fails to respond to an attack on the Victory, willfully napping through the crisis, Blair accuses him of being a coward and repeatedly insinuates that he has no flying skills. This angers Flash who challenges Blair to a simulator duel. If Blair wins the duel, he forces Dillon to request reassignment to the Victory's flight wing. Immediately afterward the Victory is rerouted to the Locanda System, where the Kilrathi are deploying a potent pair of new weapons: the "Skipper" cruise missile, equipped with a cloaking device, and a genetically-engineered bioweapon for use against the Locanda colonies, the home of Flint. Blair and his wing are scrambled to defend Locanda against several of these missiles. Even if Blair destroys the missiles, Flint breaks formation and attacks the Kilrathi forces in an act of revenge. The player is given the option to follow her, though she returns safely in either case.
Thrakhath appears with a squadron of Pakthan bombers and taunts the Victory over subspace radio, calling Blair "the heart of the tiger;" the Confed pilots gather the Kilrathi have bestowed this name on him as a sign of respect. Admiral Tolwyn rendezvouses with the Victory, escorted by several destroyers. Tolwyn is responsible for the escort and defense of the TCS Behemoth; an extremely large vessel with a forward cannon capable of destroying a planet. Following a successful field test of the Behemoth in the Loki system, the Victory jumps to Kilrah and Tolwyn prepares to use the Behemoth on the Kilrathi home world. Thrakhath's forces attack the Behemoth. A traitor aboard the Victory has transmitted targeting data to the Kilrathi revealing the Behemoth's weakpoints, and the Behemoth is destroyed. Thrakhath then challenges Blair in single combat. He taunts Blair with a recording showing how he personally disemboweled Angel after her colleagues were disintegrated. Blair's instinct is to accept, but Lt. Ted "Radio" Rollins warns him that the Victory is leaving the system. When he returns to the Victory, the player chooses between getting drunk or talking to Rachel about his loss. If Blair gets drunk, he must then fly an emergency scramble drunk, with the game controls not responding reliably, making combat virtually impossible.
After a retreat to the Alcor System, Paladin arrives. He reveals that before Angel was captured, she transmitted data indicating that the Kilrathi home world is seismically unstable. Paladin suggests a weapon called the Temblor Bomb which, if dropped in the right place, will cause the planet to shake itself to pieces. Before they can complete the bomb, Hobbes kills one of the Victory's pilots, Lt. Laurel "Cobra" Buckley, steals her fighter and makes for Kilrathi space with news of the planned T-Bomb attack. Blair has the choice of chasing him or letting him go. If he gives chase, he kills Hobbes, the carrier is attacked, and Lt. Mitchell "Vaquero" Lopez is killed in the fight. Either way, afterwards Blair finds Hobbes left a message locker, explaining that he was brainwashed long before he met Blair, and this brainwashing led him to defect to the Confederation. His original personality was reactivated by the code phrase "heart of the tiger", the Kilrathi name for Blair. (How Hobbes had never heard this phrase before Thrakhath's recent transmission is never explained.)
Blair has the option to choose to initiate a romance with Flint or Rachel. Flint refuses to fly with him if he chooses Rachel, Rachel refuses to help him with his missile loadouts if he chooses Flint, and both are bitter with him if he chooses neither. Blair launches against Kilrah, with up to three wingmen of the player's choice. This attack comes just as the Kilrathi prepare for a massive and devastating strike against Earth, intending to finally force humanity into submission with the loss of their home planet. After successfully downing Prince Thrakhath above Kilrah (and Hobbes, if he was not killed earlier), Blair descends to the surface and delivers the bomb. The resulting explosion destroys Kilrah and wipes out nearly the entire Kilrathi armada assembled in orbit, but damages Blair's fighter as well; a surviving Kilrathi capital ship tractors him in. Morally devastated by the destruction of their home planet, the Kilrathi, commanded now by Thrakhath's retainer Melek nar Kiranka, surrender to Tolwyn. The surviving Kilrathi begin to colonize a new homeworld and now want to live in peace and harmony with humans.
