SCi Entertainment Group Plc extended a share offer for its rival Eidos Plc, the producer of ``Tomb Raider’’ video games. Shares of Eidos have lifted considerably in recent five years.

SCi (``The Great Escape’’game producer) offers 53.6 pence per share for Eidos.

But Eidos has earlier agreed to accept the $135 million offer from Elevation Partners, a buyout fund which valued the company at 50 pence a share.

SCi will offer one share for every six shares of Eidos, valuing Eidos at 76.1 million pounds ($144.6 million), SCI officials reported yesterday.

It was also reported that about 15% of Eidos shareholders OKed the offer.
