In response to a story from earlier in the week that Blizzard was banning players from StarCraft 2 who used trainers or cheats in the game’s single-player component, the company issued a clarification.
The web site Cheat Happens had claimed that gamers who used its trainers, which grants users unlimited ammo or other cheats, in SC 2's single-player element resulted in users having their Battle.net accounts suspended, or their CD keys disabled.
In an article on IGN, Blizzard stated that they are not banning players just for cheating StarCraft 2’s single player, but that it was banning for hacks installed which affected both the single player and multiplayer parts of the game:
It's important to point out first, that many of the 3rd-party hacks and cheats developed for StarCraft II contain both single and multiplayer functionality.
In order to protect the integrity of multiplayer competition, we are actively detecting cheat programs used in multiplayer modes whether there are human opponents or not.
The company stated that “any players who opt to use any type of 3rd party hacks do so at their own risk,” adding that “there are already built-in cheat codes for StarCraft II single-player that can be used safely.”
Cheat Happens, responding to the Blizzard statement, said that the newly issued proclamation “completely contradicts” earlier correspondence it had receive from Blizzard support.
