-Easy Mode Walkthrough (PC) by vjsmyth
- Updated: 01/27/2024

-This guide is covers Easy mode. Normal and Hard Mode puzzle solutions are the
same as except for 2 sections noted where it comes up.

-Finishing the game on Easy will not unlock Hard mode- must do it on normal.

-Differences between Easy, Normal and Hard mode save system (using the Voice
Recorder battery) outlined below. There is no way to recharge it.

Easy: Start on 99. Saving costs 3, loading is free.
Normal: Start on 64. Saving costs 3, loading costs 1.
Hard: Start on 16. Saving costs 3, loading costs 2.

-Story spoilers removed from here

-Maze directions mean keep following path until have actual crossroads then take
the next direction in the sequence. E.g. if the path has an L shape with no
turnoffs it's not "turn right" 

-Maps have been uploaded to GameFAQs separately with routes marked for the
mazes. Not to exact scale for corridor lengths but layout and directions are
right.

Disc 1
======
-Examine drawer unit in corner (Laura's keycard and voice recorder)
-Examine lab equipment (VPS scanner)
-Use terminal to call Parker and Ronny (optional?)
-Exit

-Take first right and enter Store Room
-Use terminal in corner to unlock all doors
-Exit
-Take a right and take the next right
-Straight until T junction, then left to Locker Room door
-(Note: on Normal, the box in front when you start is for charging your gun)
-Use Laura's keycard on Laura's locker (stair keycard)
-Exit

-Turn left and head all the way south to the Stair Room door
-Use stair keycard
-Keep pressing forward to enter basement

-Follow path around
-Turn left and enter Power Room
-Use power terminal: first button and the last two buttons on then power
-Exit and head straight through roller doors
-Hug left wall through maze (except for the small open area) until can enter
Parker's Room. Ignore proximity warnings, alien won't get you if you keep
running and don't stray. There is a more direct route if look at the map but
alien is always blocking it.

-Check drawers for Kimberly's code (0326)
-Stand in front of terminal and check code in inventory first
-Use terminal to call Kimberly then call Ronny
-Exit and hug right wall back through the maze until back through shutters.
Ignore proximity warnings again, as long as stay running and don't stray. Coming
back you can take the riskier direct route as alien can have moved.

-Head left back up to and through the Stair Room to the first floor

-Take first left and straight through to the T junction
-Take the right into Mercer's room (door should be broken)
-Interact straight away to Examine body (Mercer's hand)
-Use Mercer's hand on keypad scanner
-Interact with locker (gun)
NOTE: If not playing on Easy, will need to charge gun in Locker Room first
before going to Elevator

-(Can go to basement to kill alien but completely optional)


-Exit (recommend saving first) and take first right
-Take first door on left towards Elevator
-Kill alien about mid point of corridor
-Enter Elevator (lose gun)

-After cutscene, immediately turn left and run to end of corridor
-Look up (C and Up Arrow) and go through the vent

-Duct Maze Part 1 to Archives
Right, right, left, straight, right (ride conveyer belt), left, right, enter
hatch

-Use PC tower
-Use monitor
-Use PC tower again (blue keycard)
-Go to locker and use blue keycard (get gun)
-Use blue keycard on slot below vent to exit

-Duct Maze Part 2 to Tool Room
Right, left, left, right, left, enter hatch
(NOTE: CAN GO STRAIGHT TO EXIT ON EASY MODE AS GUN IS PRECHARGED WITH 3 SHOTS.
HARD MODE GUN ONLY HOLDS 1 CHARGE.)

-Use gun on charge port
-Password is "George"
-Exit (recommend saving first here)

-Kill alien and head to exit barrier:
Right, left, left, left, straight (long walk), straight x2 to T junction, right,
left and there should be an alien in this corridor right in front of the barrier
on the left. Doesn't seem to roam or move from this position.

-Kill the alien, head back to recharge gun if empty (can use conveyor belt on
the right while retracing steps to save time- turn right after getting off it)

Check personal file photo
Call David
Call George, Mercus, Ronny and Parker

DISC 2
======
-Straight, right, right (through three red doors- long walk), left (up ramp),
through doors
-Enter Elevator
-Set panel for floor 7 (all switches up)
-Enter Ronnie's Room (PRESOLVED INITIALLY ON EASY, JUST HIT ENTER)
Keypad code: 
Down Up Down
Up Down Up
Down Up Up
Down Down Up

-Use sunglasses on calendar to see PC password

George first)

-Look at photo
-Head back and talk to George
-David should now be in the basement storeroom (doing all the above is mandatory
to trigger this event) 
-Head back to Elevator and select basement (all switches down)

-Go to Basement Storeroom (recommend saving)
Head northwest through corridor, left and immediately right, take second left
and straight to the door. 2 aliens roaming, appears to be RNG for starting
location. You can make it to the door sometimes by running as fast as possible-
but have found consistently that walking will avoid aggroing the aliens. If done
everything right, the outer door will be broken open and able to go straight in.
If door is locked, need to go back up and check everything else is done.

-Charge gun on left if need to
-Pick up paper from table on right (puzzle solution for later Power Room if
needed for reference but is optional)
-Walk around the corner
-Interact with David (computer chip)

Head straight to T junction, turn right, straight until can turn left (and take
it), immediate right and head diagonally to the door

-Set panel for floor 5 (up, down, up)

Keypad code: 
Down Up Down
Up Down Up
Down Up Up
Down Down Up
-Use key on body scanner in corner
-Exit back to Elevator
-Set panel for floor 5 (up, down, up)

-Enter David's Room
-Walk around to the door and turn around
-Interact with George TWICE (orange keycard mandatory, and code for Power Room
on second one but solution is below)
-Exit back to Elevator
-Set panel for floor 6 (up, up, down)

-Head to Power Room (doors not listed here- just follow corridor until reach a
junction then take option shown). 1 Alien here, near the end.
Left, left, right, right, right, straight

-Use power terminal
180, 270, 0 (can actually just hit Enter by itself and it counts), 135

-Head to Elevator
Straight, left, left, left, right, right
-Recharge gun in George's Room (up, down, up)
-Head to floor 1 (down, down, up)
-Recommend saving before exiting Elevator
-Head straight to door controls
-Use orange keycard to trigger transition to Disc 3


DISC 3
======
Note: small enemies respawn but regular Aliens do not.
-F1, head to F2 (1 Alien- go direct and don't stop, won't catch you)
First right, left then right into elevator

-F2, head to F3 (1 Alien- go direct and don't stop, won't catch you)
Straight until reach pillar, take first left and straight until elevator

-F3 to Safe Room (F4 junction point)
Straight until reach pillar, take first right and straight until room

-Exit out far door to F4(automatically picks up new gun with unlimited charges)
SAVE BEFORE EXITING. NOTE: THIS IS THE ONLY SAVE SPOT UNTIL REACH F9 EXIT SO BE
PREPARED TO BACK TRACK TO HERE

Note: Small aliens don't require fully charged shot to kill.

WARNING: SEEMS TO USUALLY BE A SMALL ALIEN CAMPING THIS DOOR IF LEAVE FLOOR AND
COME BACK

-F4, head to F5 (small aliens only)
Right, right, straight to elevator. Watch for small aliens at junctions- you
should be able to hear them. If one passes a junction in front of you, wait as
it WILL turn around and come back.

-F5, head to F6
Keep straight all the way until path turns right, take first left to elevator. 1
alien but if run (only stopping to shoot small alien if in the way) will never
catch you.

-F6, head to F7 (2 Aliens, lots of small ones)
SHORTEST: left, straight, right, left, straight to T junction, right and left
SAFEST: Right, then keep going straight until reach elevator (not the most
direct but this route seems to usually make the aliens always be in front of you
for easier shots)
If can kill both Aliens recommend going back to F4 restroom to save. Watch for
small aliens at the junctions. This floor does seem to spawn more small aliens
if both Aliens are killed.

-F7, head to F8 (3 Aliens, no small ones)
Hug the right hand wall all the way to the elevator. There are 3 aliens here,
one will definitely be in your way on this path, possible other one will come in
behind you. Recommend going back to F4 restroom after each kill.

-F8, head to Boss (2-4 Aliens)
(Recommend shooting any small aliens next to vent entrances as they can follow
you in. If playing cautiously, every time you kill a regular alien go back up to
F4 and save. Walking instead of running seems to stop regular aliens from homing
in on you, but spawn points look to be slightly random)

Room 1: Straight across diagonally through the centre and enter vent (safer
route: hug left wall and walk all the way around)

Room 2: Hug left wall and enter vent

Room 3: Hug left wall and enter vent 

Room 4: Straight across and enter vent
(Note: Usually if you stay in the vent before entering Room 4 you can shoot the
alien in this room if hear proximity alarm)

-Head straight, killing boss enroute to F9 with one charged shot (warning- loud
death noise)

-F9 to Winter Tower
Straight to T junction, left, right, straight, left, right
(Two aliens in this section, appears to be random)

NOTE: CAN SAVE HERE- FIRST POINT AVAILABLE AFTER F4'S RESTROOM)
-Use White Keycard on panel on right of door (this is the Stair Room in Winter
Tower from Disc 1 again)
-Forward through all lifts
-Head to Parker's Room (same as Disc 1- follow path until T junction, right to
go through roller doors and keep left. Will likely have to kill 1 of the 2
Aliens roaming. This time though can take the more direct route as have gun)
-Scroll through computer log
-Exit and run back to lift. Either direct route, or safer way of hug right wall
until back through the roller doors. Once through roller doors, take the left)

-Head all the way through the lifts back to the maze
-VPS will lose power, no radar warning
-Follow directions from intercom. When told "Enemy is near" don't try to shoot,
just turn around and run to next junction and follow directions.

Game ends when run through open doorway and cutscene plays. On Hard Mode, a
bonus cutscene will play.
