[Episode 3] The Red Door
After passing through the Terminus and locating the Underground Space, Acarno must investigate the first of three key card locked doors.
After using the Red Key Card to gain access to the first door, you must progress through the room beyond in order to find a good place to plant the Plasma Bomb.
Behind the red door is a bridge encased in a glass tube. Equip the BIG MAGNUM and run straight across and into the dark opening in front of you.
In the next room you will immediately be faced with two enemy robots following a brief interaction with Snooper. The easiest way to take out the robots is to run out of their view, which will cause them to simply stand either side of the entrance to the room – this allows you to shoot them from a reasonable distance without even prompting a response. Four shots per robot will be enough.
Note that the robots sometimes drop items – there appears to be no logic to this, the game simply decides if it wants to drop them or not. They are never key items, so don’t worry if you don’t get anything.
To one side of the room there is another cargo vehicle with penetrable rear doors you can remove in order to gain some items.
Jump on top of the vehicle and equip the SPIKED BOOTS. Standing on the back of the vehicle turn to face the large, dormant robot in the middle of the room. Jump as shown below;
Now that both arms have been removed, an item is revealed on each side of the robot – see below;
After collecting all of the items the robot has to offer, leave the room the same way you came in and emerge in the glass tunnel again.
Secret; After successfully navigating the area behind the red door, your next stop is the silver door to use the relevant key card. There is however something else you can do before this if you are true “completionist”; it involves back-tracking to the room at the top of the long staircase in order to operate the trailer for which you found a KEY FOR OPERATING TRAILER earlier along with the BOTTLE (WITH OIL). If you have these two items, plus the ENERGY PACK from beyond the red door, you are able to raise the trailer and reveal a totally useless item.
Or you could save yourself the hassle and just watch the above video taken from the OverBlood2.com YouTube channel.
