Perhaps the best way to describe the Type Two is that they reanimated wrong. Many of them seem a bit dis-formed or gangly, and almost all show open sores or pustules, often displaying a kind of quicksilver like discharge. Tumors and discolored patches of skin can be commonly found - hair a bit less so - often its missing in spots or gone entirely. In short, almost all of them look like victims of some terrible industrial accident, horrific disease, or chemical weapon attack.
Don't let these seeming injuries fool you however. They are not slowed down, addled, or falling apart - quite the opposite really. These reanimates are more like packs of Hyenas, if Hyenas could climb walls and ignore a load of buckshot to the face. Reports commonly describe them harrying victims, or one runner driving prey into an ambush set by the rest of the pack.
Treat a Type Two as you would treat a bloodthirsty Samurai wearing a flak vest, and perhaps you will survive the encounter.
Type Two Reanimates use the Necrotic Threshold - SDI 4, NT 1 NP 3 - meaning it takes three hits of at least two damage (the first "absorbed" by the NT" each to take one down. Given that a character generally only attacks once in a combat round, this is quite deadly. This gets worse, when they appear in hunting pairs, or groups of three to eight.
Stat wise, the reanimates have low technique (2), but high for a human strength of 6, Wits 4, Quick 5, and close combat 5 and DR 3, though only ranged of one - they don't use tools often.
