(Capcom's primary storyline)
Howard is unlocked as playable in Resident Evil Outbreak but does not have a name in this game. In File #2 however, he is given a name. He can be unlocked in File #2 via Data Convert and purchased for a lower price than in the first.
There is a second version of him used for Zombies that can only be used with cheating devices. This version lacks proper stats resulting in being unable to damage enemies and running very slow. The only way to fix this is to use stat modifier cheating device codes.
