Shadow Complex Help

[Professor S]

I'm stuck. I'm at the point that the enemy have found my girl and are moving her and I have to move around on an elevator and somehow turn off a giant fan. The problem is that all the door and such are red, and I have nothing that will open up a red door and the game has locked my entry so I can't backtrack to find whatever opens the damn things.

Anyone know a way out of this?

You probably havnt searched everywhere good enough. Keep looking around, you will probably find a new place to go or find the missile launcher.

[Professor S]

Found it! Now I'm stuck fighting that rediculous walking monstrosity. I keep trying to hook up to the back to the take out it's "wires", but it's so damn hard to hit the sweet spot.

I didnt have the grapple when I got to that thing. I somehow missed it along the way. :p

But I still killed it.

[Professor S]

Oh, ok. Didn't know you could kill it without the grapple. I'll just shoot missiles at it until it dies...

[Thespis721]

Best thing I did was grapple up above it's head, shoot it until it stomps the ground and then I landed on it's head and keep firing. Repeat. And then I had one dead bug.

[Professor S]

Didn't it shoot you when you grappled above it's head?

[Thespis721]

Nope. I'd dodged the bullets and then grappled. Once over the head, it can't hit you so it stomps to knock you off.

[Professor S]

I'll give that a shot tonight and let you know how it goes.

For some reason I thought I HAD to disable the shields to beat the thing...

[Thespis721]

.... you can disable the shields? hah! that would of made it easier.
