I am not sure if this is a glitch or if it was suppose to be like this but while doing a few fsc runs, I realized that when back into a corner or against a wall the DA charge attack just blows up. I have confirmed this a few times and every time i was against a wall, the attack showed up but blew up as if it hit something right away. Like I said I am not sure if this was supposed to be this way but with the recoil the DA has, sometimes hitting a wall is inevitable.
Use the Search bar.
It's been like that for a long, long time, along with Pulsar Charges, Antigua-line explosive-projectiles, Gran Faust etc...
Apparently it was a bug that was never fixed, for whatever reason.
But really, use the search bar. This topic has been brought up lots of times I believe.
