the effects used are humongous and quite unappealing, they last for several seconds even after the rocket has been fired. using the default Rocket Launcher with removed textures is rather boring, the console likes to complain about those missing textures as well.
inside the add-on, there is a duplicate file of "IonLauncherLaser.dts", might want to get rid of that.
if this does survive a lock and failbin, it's still not a pretty add-on to look at. I can't say I would recommend it to anyone and I can't imagine many finding it fun, it simply lacks creativity and originality.
it also uses Bushido's mininuke-rocket model without his permission.
