Insanely Twisted Shadow Planet

In my opinion, the gun option isn't that good during this 'bossfight'. I kept getting swarmed by those tiny energy monsters. I've found a much easier solution:

There are four power nodes you have to overload by using the blue conductor, in much the same way you've been handling the other rooms in this world. However, now there are more and more energy beings that attack you once you start overloading (and even more once you actually have overloaded the node, multiplying in number each time you do so). You also need to look out for Cthulhu's babies; they try to pull the conductor away from you.

There is only one node active at the time; you can find it by looking for the yellow sparks emerging from the middle of the room. Once the fourth node has been overloaded, the achievement unlocks, and there is no fourth swarm of energy beings to overpower you.

I've found that even with the gun upgraded, the energy beings got the best of me. However, when using the "death ray" (the ray you obtain in the ice zone), you can easily destroy all the enemies. Just keep going with the ray at anything that nears you and you should have killed them all in no time.

This is a story related achievment and can't be missed.

To be perfectly honest, the electrical boss is probably the easiest in the game.

The room is dark, and in the centre is an eyeball. Ignore it. At the four clock points of 12, 3, 6 and 9 there is an electrical socket. All you have to do, is insert the conducter then overload it into each socket.

They have to be done in a certain order, whichever the boss is sending power too. For me, it was the order above : 12, 3, 6, 9.

After each overload, a ton of sparks will attack you. Just fly away and use your machine gun to kill then, Once they are dead, move onto the next point.

Once all four points are overloaded, the achievment will pop.
