Scriptwelder makes some ****** games, I actually played through this before he had quests for it.
Full walkthrough for quests (full game walkthrough first for The Truth/Decontamination/Lost In Space for a single play through, others are at end).
All directions are relative to the camera, orientation does not change, so NORTH, SOUTH, EAST, WEST always correspond to TOP, BOTTOM, LEFT, RIGHT of screen.
Walkthrough:
1) DO NOTHING (alternately click the panel to the right of the door and click EJECT). You get sucked out into space and die, SPACED achievement earned
2) Restart, click the PANEL to the right of the door, click 'RESTORE SAFETY PROCEDURES', then 'ABORT EJECTION PROCEDURE' (this is the only time-sensitive part of the game). Then click 'OPEN INTERIOR DOOR'. Go SOUTH
3) Pick up the DATA PAD, click on 'MAP', 'STATUS' and 'LOG 01'. Read if interested in story, then exit out and go EAST TWICE.
4) Pick up the PLASMA TORCH. Go EAST TWICE again to enter the BRIDGE.
5) Pick up the FUSE. Click on the COMMUNICATIONS CONSOLE, then click on the CAPTAINS CONSOLE and click on ACCESS MISSION ORDERS.
6) Go WEST FIVE TIMES (sign with Engineering and Lab on the walls). Open the FUSE BOX, and insert the FUSE. Then go NORTH to enter the LAB
7) Click on the DATA PAD under the table. Pick up the FLASK on the table, get some ANTIBIOTICS from the First Aid Kit on the wall. Go SOUTH, then EAST THREE TIMES to get back to the QUARTERS, go NORTH to enter QUARTERS (now lit with strobe light)
8) Take the KNIFE from the body. Use the FLASK on the body to get a BLOOD SAMPLE. Touch the FOOD DISPENSOR three times to get PANCAKES, FOOD RATION, and ALCOHOL. Then go WEST to the bathroom.
9) Open locker, take DETERGENT. Go EAST twice. Pick up the DATA DISC and FUEL TANK from the floor. Take PLANT LEAVES from the bushes.
10) Go W, S, E and use the KNIFE on the GRATE, then pick up the KEY.
11) Go Wx4 N to get back in the LAB. Use the KEY on the LOCKER. Pick up the GLASSES and a bottle of ACID
12) At this point if you are interested in doing the work yourself, you can use the ANTIBIOTICS, BLOOD SAMPLE, ALCOHOL, PLANT LEAVES, DETERGENT, and ACID on the Chemical Analyzer to give you a breakdown of the components and look at them in you datapad under 'Chem Analysis'. Then you can check the PAPER on the desk that gives you 2 formulas - 1 for Crystal Dissolving Formula (which we are making now), and another for Explosive Amplifier (which we will make later, we only have 1 flask).
13) In either case, load PLANT LEAVES, ANTIBIOTIC and BLOOD SAMPLE into the CENTRIFUGE and click MIX, then use the FLASK on the CENTRIFUGE to make CRYSTAL DISSOLVING FORMULA (it just says Chemical Mixture). Pick up some replacement ANTIBIOTICS from the First Aid Kit.
14) Go S, use the FUEL TANK on the PLASMA TORCH. Click on the DOOR to Engineering, then click on the PANEL in the center of the door. Use the GLASSES on YOURSELF, then use the PLASMA TORCH to cut through the dotted outline of the PANEL. Pull the LEVER to open the door.
15) Go W, pick up the ACCESS CARD, go E x3, use the ACCESS CARD on the ESCAPE POD and go N to enter. Pick up the TOOLS, then go S, W, N back to the AIRLOCK
16) Use the ACCESS CARD on the SUIT to get the SUIT. Put the SUIT on YOURSELF, then click the PANEL. Click CLOSE INTERIOR DOOR, DECOMPRESSION, then OPEN EXTERIOR DOOR. Click the AIRLOCK. Click the panel on the wall to tie the ROPE to yourself, then click towards the DEBRIS in the distance. Move a couple panels of wreckage out of the way and pick up the CRYSTAL. Then go back to the airlock, hit CLOSE EXTERIOR DOOR, RESTORE PRESSURE, OPEN INTERIOR DOOR, then go S, Wx2.
17) Use the TOOLS on the circuit to repair the fans, then go W then N. Pour the CHEMICAL MIXTURE into the FIRE SPRINKLER CIRCUIT ACCESS POINT. Click on the LIFE SUPPORT CONTROL, hit ACTIVATE AUXILIARY LIFE SUPPORT (this gives you 3 more hours of time), then FIRE SPRINKLER MAINTENANCE, and test them on the ISOLATION WARD. Then use the DATA DISC on the WORKSHOP STATION, and make a PORTABLE IGNITER and a DATA PAD MKII PROCESSOR. Use the DATA PAD PROCESSOR on the DATA PAD to upgrade it. Then go S and E back to the room with the BODY.
18) Now you need to go to each room with a body, open your DATA PAD, and click SECURITY CAM to decode the recording. After each one, you will get 1 number of the code to the panel in the QUARTERS. The code is different every game, so don't ask what it is. So click through the first guy dying to get the first number.
19) Go E, N, W to enter the ISOLATION WARD. Open the locker and get the EXPLOSIVES. Use SECURITY CAM to get the next number.
20) Go E, S, Ex3 to the next BODY. Us e SECURITY CAM to get the next number.
21) Go N to the last BODY, use SECURITY CAM to get the last number.
22) Go E, pick up some replacement PLANT LEAVES, then enter the CODE into the PANEL to open the door, go E and click the LIGHT SWITCH (small green light to the left). Click on the SUIT to get THE TRUTH achievement and get the BLOODY CRYSTAL. Open the LOCKER and get the CAPTAINS ACCESS CARD.
23) Go Wx2, S, Ex2 to the BRIDGE. Use the CAPTAINS ACCESS CARD on the CAPTAINS CONSOLE. Click SAFETY PROTOCOLS, and DEACTIVATE.
23) Go Wx5, N back to the LAB, and use ANTIBIOTIC, ALCOHOL and PLANT LEAVES on the CENTRIFUGE to get EXPLOSIVE AMPLIFIER (says Chemical Mixture)
24) Go S, Wx2. Use the CHEMICAL MIXTURE on the EXPLOSIVES. Use the IGNITER on the EXPLOSIVES. Put the EXPLOSIVES on the POWER CORE. Detonate the explosives to get DECONTAMINATION and LOST IN SPACE
25) Click CONTINUE and pick up the EXPLOSIVES from the POWER CORE. Go Ex2, N, W to the ISOLATION WARD (room with the crystals). Put the EXPLOSIVES on the CRYSTALS on the table and detonate to get HULL BREACH
25) Now click CONTINUE to go back to the ship. Go to the ESCAPE POD and eject it to get ESCAPE POD
There you go, six quests done!
