Rango

You will be on a large circular platform and the Alien Probe will be in the center of the room on the ceiling. You must shoot the "eye" of it when it opens up, all while avoiding its different attacks and random enemies that appear throughout.

His attacks vary, so you'll have to watch out for what he's going to do. He can do the following:

1) Send lasers across the floor in criss-cross patterns (Just jump to avoid them)
2) He will send a shock wave blast down to the middle of the floor which will then expand outward across the entire platform (again, just jump to avoid)
3) He will shoot a laser down to the floor and it was chase you are the room for a while (just run around and dodge when needed)
4) A bunch of lasers will start coming down in one area and then come together quickly and explode there (run away or dodge)
5) After he's been damaged enough, he will begin combining some of the previous attacks at one time (especially the 2nd & 4th together), plus the remaining ones will move a lot faster and are harder to avoid.

Just keep attacking him when you can and once you hit the eye enough times, the fish controlling it will drop down into the center of the room dazed. This is when you want to unload into it to do damage against him. Keep repeating hitting the eye and then hitting him when he's dazed until you finish him off. Once you do, the trophy will pop!
