[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 the next key card.
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.
To one side of the room there is another cargo vehicle with explodable rear doors 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;
Once both items have been collected, you next need to blow up three separate parts of the robot to reveal three more items – see below;
After dismantling the robot, there are now some more items to collect;
Drop carefully to the floor and exit the room back onto the bridge encased in the glass tube. You’ll notice when looking at the glass tube it is divided into three sections. Stand in the middle of the three sections equip the HAND BAZOOKA.
After collecting the final two items on the ledge, use the HOOK SHOT to exit this room via the doorway you originally entered using the Red Door. Once back in the room with the four coloured doors, head over to the silver door.
