Retailers, particularly in North America, have begun discounting prices "above our expectations," say Eidos.
Many are also "restricting inventory levels" and full year revenue is expected to fall below forecasts. Batman: Arkham Asylum maybe the saving financial grace for Eidos in 2009.
"On a global basis our sell through to 31st December, which we estimate at approximately 1.5 million units, is below our internal forecasts, primarily due to a lower start in North America," said the company.
"In a difficult North American economy, we have seen retailers restricting inventory levels and...products priced discounted above our expectations."
While a videogame shifting 1.5 million units is a respectable achievement, Eidos was hoping to bring home more bacon from the latest Lady Croft adventure.
They've had to reassess their revenue predictions for the year and are now £20m down, expecting to rake in between £160 million and £180 million. Luckily Batman: Arkham Asylum should boost profits again when it releases on Xbox 360, PS3 and PC.
