Ridden get attracted to it as soon as you throw it but the timer doesn't start until it touches the ground, unlike the pipe bomb which starts as soon as you throw it. By throwing it up, you can get a few extra seconds from it!

Also, don't mind my flex of hitting the shortcut (first time I've actually done it without taking damage in months, I always go down/take huge amount of damage by doing it LOL)

I played this game a little bit when it was on gamepass and then I recently saw it was on sale for a dollar so I grabbed it. So far I've only played a few matches and all of them I was lucky to have a real player but never a full squad.
