You must stop Dr. Spacegad.
You’ve lost your access card so you can’t get out. Walk to the right and use the toolbox to take the KEYMASTER 5000. Walk to the left twice and use the keymaster on the locker on the upper left in the window. Inside the locker is a CUTTER and TWO WIRES. Walk to the right twice, back to the toolbox and use the cuttor on the toolbox to take a metal BAR from it.
Walk back to the left. Use the wires on the hole in the door. Use the metal bar first on the wires attached to the door and then use the metal bar on the console to the left of the door. The power shortage opens the door.
Dr. Spacegad has been located and you’re teleported to the casino. But first you need to get inside. Use the scanner on the door to find you don’t have access. Walk to the right to find a dead alien body. Take the cutter from your inventory and use it on the body to take a piece of ALIEN with you. Walk to the left twice and talk to the guard. Ask for his gun and when he asks for proof of your story give him the piece of alien. He’ll give you his GUN.
Walk to the right twice again and use the part of the wall that comes forward a bit. You make a hole and find a safe but the hole isn’t big enough. Use the gun with the hole to make it larger and you’ll take the Gorgon’s HAND with fingerprint out. Walk to the left and use the hand on the door to enter. You can then overhear a conversation.
When a gun is pointed at you, take the gun. Take the WIRES that are attached to the door and walk to the right. Use the toolbox to find an ELECTRIC SHOCKER. Walk to the left twice to see the attackers that you must get rid of. Use the shocker on the window to create a hole. But it isn’t big enough. You need more power. Use the wires with the shocker on the window and then use the extension cable with the wires. Walk to the right and use the other end of the extension cable on the hole in the door. The hole will be bigger and the attackers will be killed by the vacuum.
Walk to the north to enter the casino. Talk to the man with the glasses next to the plant about b… and when he asks you if you are Dee’s man tell him you are. He’ll give you the MONEY. Walk to the south and to the right. Give the money to the barman to buy a DRINK. Give the drink to the casino owner at the bar and he’ll pass out. Use his body to find the COMBINATION to the safe.
Walk to the left and use the painting to reveal the safe behind it. Use the paper with combination from your inventory on the safe and you have your GUN. Walk to the right and use the gun on the casino owner to find out where Dr. Spacegad is. You’ll then receive a blow to the head.
Standing in front of a giant killer robot, use your gun and shoot the armor. You’ll then be teleported just in time and join Mike. Together you can capture Dr. Spacegad.
