Ladies and Gentlemen:

par value $.000001 per share (the "Common Stock") held by certain of the
Company's stockholders.

          We are familiar with the Amended and Restated Certificate of
Incorporation, as amended, and the By-laws of the Company and have examined
originals or copies, certified or otherwise identified to our satisfaction, of
such other documents, evidence of corporate action, certificates and other
instruments, and have made such other investigations of law and fact, as we
have deemed necessary or appropriate for the purposes of this opinion.

          Based upon the foregoing, it is our opinion that:

          (a)  The Company has been duly incorporated and is validly existing
under the laws of the State of Delaware.

          (b)  The 62,652 shares of Common Stock being registered for the
account of certain of the Company's stockholders have been duly authorized and
are validly issued, fully paid and nonassessable.  The 150,000 shares of Common
Stock being registered on account of the warrant issued to id Software, Inc.
have been duly authorized and, when issued upon exercise of such warrant and
payment of the purchase price therefor, will be validly issued, fully paid and
nonassessable.

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name wherever appearing in such
Registration Statement, including the Prospectus consisting a part thereof, and
any amendment thereto.

                                   Very truly yours,
