French publisher Gameloft has used its Facebook page to issue a formal apology over the recent switching of its God of War-esque slasher Hero of Sparta 2 into a free-to-play title.

The complaints mainly centred on the addition of adverts to the formally premium title - a move that understandably upset those that had originally paid money for the game.

Gonzague de Vallois, VP of worldwide publishing for Gameloft, said in a statement that the company had listened to these complaints, and admitted that "the gaming experience has been dampened in this new version".

"With the craziness of the Christmas period, this game update didn’t go through our usual quality process."

Gameloft has now removed all adverts from the game and reinstated the Bronze Award winner's £2.99 / $4.99 [buy] price tag.
