Hero Skills, also erroneously called Killstreaks, are a feature in Call of Duty: Heroes. They are special abilities available to Heroes in PvP matches that use Skill Points to activate. With every usage in that attack, the cost increases. All heroes except for Soap and Harper have three available skills; the aforementioned two have only two instead. Most skills are available to several characters, although a few are exclusive to one such - Ilona and Wallcroft are the only two Heroes that have all three skills exclusive to themselves.
