Note: You must have the cop uniform selected. When Alex first gets home, grab the pistol as usual by the bunk bed and continue with the game. After the 2nd visit from the crypt, go back to the bedroom again and grab the Lazer Pistol before darkness falls. At the police station all of Alex's weapons are stripped, but when Alex gets to the underground room his pistol is still in his obsession. That saves tons of time killing at least 10 Order Soldiers and Curtis.
