[Episode 3] The Gold Door
After exploring what was behind both the red and silver doors, Acarno and Snooper have one final door to unlock in order to find a location to detonate the Plasma Bomb.
Unsurprisingly, the detonation spot is behind the (third and final) gold door. To progress you must find the right location.
There are some items collect in this room before proceeding any further;
There are some items to collect before making your way up-to the Anti Proton Core suspended from the ceiling in order to detonate the PLASMA BOMB;
Once the PLASMA BOMB has been set, a countdown timer will appear – simply wait for it to run out.
Following the successful detonation of the Plasma Bomb in The Underground Space, Sperio appears on his junk blade in order to try and foil Acarno’s escape.
Sperio must be dispatched before you can progress any further.
Distance yourself from Sphereo by running away and equip the BIG MAGNUM. Landing four shots on Sperio should be enough to take him out.
Following the cutscene, you will be given instructions on how to control the junk blade before you begin your escape from The Undeground Space.
The chase lasts around sixty seconds. Try your best to avoid the walls on both sides of the tunnel and the rocks sticking out of the water. Although you will no doubt sustain several blows along the way, you should easily be able to sustain some damage and still progress.
