What to take

The only thing you must take is the red transmitter. The regular gun and the energy recovery pills are recommended choices as well. You can, if you want, take the wide cannon: some people find it easier to shoot down the helicopter soldiers with it.

[edit] Walkthrough

Some people use the Wide Cannon to shoot down the helicopter soldiers. However, the best way to get past them is to climb quickly.

Go up until you find the transmission room. Receive all messages. Exit. If you are having trouble finding your way, remember that you can attach your grapple arm to the lights. Continue upward until you reach the second transmission room. Receive all messages. Be careful, after you wire-tap, an alarm will go off and enemies will appear. Get out of the room quickly. Continue upward until you reach the boss door. Enter. The spring pads may be a bit tricky at first. Just make sure you are facing a platform you can grapple when you climb on them. This boss gets in your way. You have to kill him. Stand on the first wide platform and shoot. Dodge his shots by either falling off the platform or using the grapple to climb up on a higher platform. Once he is dead, destroy the core.
