Re: Other Items for Wardogs
Cloak was really discussed in the very early versions of the rules. It was not included as a separate system for a variety of reasons.
Visual doesn't mask heat... Star Fist books are a good one on this where the uniforms are camo/cloaks and are detectable by thermal scans. If you were to use a cloak device in your own games, I would make it a bonus defense against melee combat only for this reason. But it's up to you in the end.
