So far so good on characters, if you feel like you want to add stuff overall. I know you guys are going, "I don't want them to be overpowered," but let me make it clear -- a lot of the vamps go beyond just the strength and speed thing and they are hideously tough. The typical one can pretty much do a squad of infantry very quickly and with minimal damage to themselves. 

I put out that one character sheet to give an appreciation of the various small things that can be added in, such as retractable blades, built in firearms and magnetized feet, hands and knees. 

Don't forget your drones, either. ;)
