Eidos Interactive have admitted this morning that of their game, Underworld, have not lived up to expectations, the company admitting that North American sales of the game are below forecasts.

This admission sees the British publisher revising its full year sales forecast, knocking 20 million GBP off their outlook, moving their prediction from 180 to 200 million GBP, down to between 160 and 180 million GBP.

Shares in the game maker lost 25% of their value, falling to 13 pence.

Eidos said heavy discounting in North America, coupled with reduced stocks on shelves, had hurt forecasts and may lead to discussions with banks regarding the firm's finances.

Eidos' big hope for 2009 appears to be Batman: Arkham Asylum. More soon.
