"Within this searing crucible writhes a vengeful demon: Viper, whose fiery fury grows and threatens to engulf everything..."
Biochem Plant (化学工場 Chemical Plant) is a Boss Stage in Azure Striker Gunvolt. It is the setting for the mission Conflagration. Gunvolt's objective here is to infiltrate and destroy a Sumeragi biochemical plant.
Asimov: This time we'll be raiding a Sumeragi biochemical plant. I want you to place a bomb at the heart of the plant.
Gunvolt: Roger that. What's my means of infiltration?
Asimov: There's a freight train that makes regular supply drops there. If you hop on board, you should be able to reach your destination. I'm counting on you, GV.
Stage CompositionThe first area of this stage is the supply train. On this train are many containers, including new explosive containers that self-destruct when tagged or shocked by the Flashfield, as well as many Sumeragi soldiers. Once reaching the end of the freight train section, Gunvolt will have to fight the Spyder Unit, the miniboss of this stage.
After destroying the Spyder Unit, Gunvolt will be able to destroy a hexapyle and enter the biochem plant itself. Once inside, he'll have to deal with masses of containers, as well as bomb robots that drift towards Gunvolt and explode once damaged. There are also many conveyor belts that carry containers into the lava, which Gunvolt has to carefully maneuver through. About halfway through this section, there is a large pile of containers that must be destroyed in a certain order, as in this mass of containers lies the Jewel for this stage. After all of this is the boss, Viper.
Miniboss: Spyder UnitBefore arriving at the biochemical plant itself, Gunvolt will have to fight a miniboss: the Spyder Unit. This boss can fire bombs and a laser, as well as climb on top of the ceiling. Gunvolt can get his chance to tag the Spyder once it opens its core to fire its laser.
The Jewel is located right after the first enemy room after the hexapyle. You'll have to break the boxes in a specific order. This is a tricky Jewel to get, so, preemptively, if you haven't been passing through the checkpoint markers, go through the one in this room just to be safe. If you mess up, you can go to the pause menu and click "Retry" to try again from the last checkpoint.
First, destroy the first two heavy boxes and the two light boxes under the leftmost explosive box. This will cause the first explosive to fall. Tag it with one shot and it will destroy the light box under it. Move to where that light box was and shoot the other light box that was directly next to it, as well as the heavy box that was behind this one. This will cause another group of boxes to drop. Shoot the explosive box that is now on the ground directly in front of you. Move up and tag the heavy box just in front of the jewel. Back up once you've tagged it before you use flash field and then destroy the box, causing two more explosive boxes to fall down. Hit the explosive box and you can now access the jewel.
The slightest falter in this pattern will ruin everything, so be careful! Arguably, this is the hardest Jewel to obtain.
