Just about every modifier except the last two are in the open and relatively easy to locate.

Especially after beating the final boss (there's a large blue orb similar to the ones from the drones and other bosses that you have to get after it dies) and unlocking the general locations of the modifier orbs on the map. All you have to do is go to around where the center of the sphere is and you should be within eyesight of it. All the modifiers give off a strong purple glow.


The last two modifier orbs however are hidden out of eyesight, inside parts of the map, and therefore much more difficult, for you can't see the purple glow that the orbs create.

The first seems like it's inside of the mountain beside the tutorial area, and it is.

Go to the top of the mountain and look around the towers there. There's a hole in the tower facing the tutorial area, inside the "O" part at the top. The hole is in the bottom of the "O"

Tower kinda looks like this:

Going through the hole takes you through a very tight squeeze, at the end of which is a large room with the modifier in the center.



The second one is within the end tail section of the Worm.

Fly to the very end of the worm, and move up the section until you get to the large rectangular indents in each side his tail section.

In one of the sides, there's a hole that takes you inside a chamber, and the orb is at the far end.

Jet Island is by far one of the most fun VR games in existence currently. It's definitely my favorite.

The modifier update made it much more fun to be able to treasure hunt and visit all the structures that you wouldn't normally stop to look at soaring at 350+ mph through the air, haha. Not to mention playing with the modifiers themselves.

I very much look forward to any future updates and hopefully there are much more planned. especially like custom bosses/maps/mod support.

Anyways, have fun and god bless
