MFC Grenades: Super Cheap and easy to make. Really powerful with 3 ranks of Demo Expert
MFC Cluster: A great land mine type weapon. Again super easy to make sense it only requires MFC, Duct Tape and Scrap Electronics. Does a whole lot of damage
Nuka Grenades: A classic returns. Requires the Nuka Chemist perk, but that gives you an almost unlimited amount of them. Big damage, big explosion! Love it.
I am a little disappointed in the Tin Can Grenades. The duct tape is better spent making MFC Clusters. The improved Bottle Cap mine is nice too. However, Satchel charges are a lot easier to make.
So what does every else think about this perk?
