In order to stem the enemy threat that is building up within this base in the mission Into the Lions Den, you are now tasked in the fourth mission of this episode to eliminate the heavy artillery that the enemy is building up. You will be taken to a new location featuring both indoor and outdoor areas.
Map and Objectives
– Primary Objectives –
Destroy all of the heavy tanks.
First things first is to head to the outdoor area (red line) that previously was the route to the exit portal, in order to trigger the pad at point A. Doing this unlocks the forcefield at point C, allowing you to progress further and spawning a Heavy Proton Tank to fight at point B. If you previously did not acquire the Storm Plow, or if you swapped it out in another level, you have a second chance to pick this weapon up at point 1.
Head back indoors and take the path to the right, traveling to the unlocked forcefield at point C where you will have to fight the second of three Heavy Proton Tanks in this mission. Try to use the concrete barrier just past the deactivated forcefield here to avoid its shots while firing your missiles when you have the opportunity. Once this room is cleared you can use the Teleporter to travel up the ledge (blue line).
Continuing onward in this mission we now follow the orange line, turning around the corner to trigger the pad at point D which deactivates the forcefield protecting the final tank at point E. If you haven’t acquired the Rocket Pod secondary weapon previously, there is one of these weapons available at point 2.
You can use the pipes that come out of the walls as a barrier when fighting the last tank at point E or if it comes into the room you come in from, the pillar in the center. After it is down you are free to leave the level, using the exit pad at point F.
