I was watching the WR video by LRock and I was wondering how the bosses were stunlocked as I want to try to run this game soon and was looking for advice and that came up.

It's actually fairly rhythmic. The way I do it is alternating button presses between Y and R. It took me some practice, but I eventually got the hang of it. The first Catwoman boss and the final Penguin boss are the hardest to stunlock properly since they can give themselves iframes, but it's certainly doable, as the WR video shows.

As it also turns out, I'm going to be doing a tutorial for this game which should explain it further, but I've been severely sidetracked since returning from AGDQ. I'm hoping to have it finished before the end of February, so we'll see.

awesome looking forward to it and ty for the quick response
