how do you properly use tunneler?

I've been trying to use tunneler but I can't quite figure out how it works/ how to shoot it properly. Please share your tips. ( ͡° ͜ʖ ͡°)

 

Dig a hole, dig, dig a hole, quick before the hyena come

 

it travel like in air but once it reach ground the gravity becomes the opposite,what is hard with it?It can hit even before doing a tunnel,that is something that i undertood very late in SSL xD,i thougth that subsniper was just impossible to use

 

You can shoot it underground and it will hit, that is the easiest way to use it. You can also shoot it in the air like normal but you must hit directly or it'll miss.

 

Best way to use it, is by yolo shooting it off bumpers and hoping for the best.

 

This man speaks wisely ^^^^^
Just aim it like you wold a normal shot, except aim underground o.o
