Unit 3 Level 6 - Grid Control 

Objective - destroy the security grid protecting the industrial region.

U3L6W1 (strategy)

Walk straight up the stairs, and grab the power-ups and weapons protected by the blue flashing security lasers. It’s pretty easy to watch their pattern and time it so you can squeeze in and out to snag the goodies. These lasers won’t kill you anyway so don’t worry. 

U3L6W2

Walk through the center door with the blue tinge and then go through the door on the right without pressing the button on the wall (this will activate the force-field). Now walk straight, using the same method of timing the laser blasts.

U3L6W3 (strategy)

Step on the platform, which will raise you to an outside area. This is the final showdown with this level boss Super Tank. Use the girders as protection and keep on the move. Also use something powerful to hurt this sucker. There are actually seven enemies on this level (on hard level) so save your ammo - and bravery. When the second small tank is destroyed, the ground will start shaking and the boss will emerge from the center.

U3L6W4 (strategy)

When the boss dies, the opening in the middle of the ground will be open so hop in there to the bottom. Follow along the hallway and step on the yellow platform. This will take you to the room with the power core of the huge security computer. Press the button to activate the heart of this structure (you’ll also see the flashing blue lights), then open fire to shut it down for good. Head out the door to enter Unit 4.
