I clearly remember splatting a player behind a Splash Walls he threw with my Inkzooka.
The splash wall takes like .5 seconds to actually activate. Also if you have the high ground you can direct the shot behind the wall. Though it could've just been lag.
That's because the inkzooka arcs, so if the person is too far behind the ink wall or they throw it too late and there's lag theyll get hit
As long as they stand right behind it it's fine
Pretty much that. Yeah.
