     The stockholders of Activision,  Inc. listed in this prospectus  supplement
under the section entitled "Selling Stockholders" are offering and selling up to
32,759 shares of Activision's common stock under this prospectus.

     All of the Selling Stockholders  acquired their shares of Activision common
stock in connection  with  Activision's  acquisition  on March 26, 2002 of Shaba
Games LLC, a California based console software  development company. The Selling
Stockholders were all members of Shaba. This prospectus  supplement reflects the
release of certain  shares of  Activision  common  stock  which had been held in
escrow in order to ensure that the  representations,  warranties  and  covenants
made by certain of the Selling  Stockholders  were not breached and to provide a
source of indemnification.

     Activision  will not  receive any of the  proceeds  from the sale of shares
being offered by the Selling Stockholders.

     Activision's common stock is traded on the Nasdaq National Market under the
symbol  "ATVI." The last  reported  sale price for the common  stock on April 2,
2003 was $14.60 per share.

     No  underwriting  is being used in connection  with this offering of common
stock.  The  shares of  common  stock are  being  offered  without  underwriting
discounts. The expenses of this registration will be paid by Activision.  Normal
brokerage  commissions,  discounts  and  fees  will be  payable  by the  Selling
Stockholders.

     Activision's  principal  executive  offices  are located at 3100 Ocean Park

     Activision  entered  into an  agreement  and plan of  merger  (the  "Merger
Agreement") with Activision  Publishing,  Inc., Shaba  Acquisition,  Inc., Shaba
Games LLC and the Selling  Stockholders.  The  transaction  contemplated  by the
Merger Agreement was consummated on March 26, 2002.

     Pursuant to a warranty  escrow  agreement an aggregate of 32,759  shares of
common stock, or  approximately  10% of the total number of shares of Activision
common stock issued in connection  with the merger,  were deposited in an escrow
account in connection with the  transaction  (the "Escrow  Shares").  The Escrow
Shares were  deposited in order to ensure that the  representations,  warranties
and covenants by the Selling  Stockholders  under the Merger  Agreement were not
breached  and in order to  provide a source  of  indemnification  to  Activision
pursuant to the Merger Agreement.  The Escrow Shares are subject to release from
escrow  upon the  expiration  of the  escrow  period  set  forth  in the  escrow
agreement  and are to be issued to the  Selling  Stockholders  to the extent not
used for indemnification.  In addition,  an aggregate amount of 68,965 shares of
common  stock,  or  approximately  21.05%  of the  total  number  of  shares  of
Activision  common  stock  issued  in  connection  with the  merger,  have  been
deposited in an escrow account (the "Product Escrow Shares"). The Product Escrow

                                      -2-

Shares  are  subject  to  release  from  escrow  and  issuance  to  the  Selling
Stockholders  upon  fulfillment of certain software program delivery and ranking
requirements and certain revenue requirements.

     This prospectus  supplement  reflects the release from escrow of all of the
Escrow Shares as a result of the expiration of the escrow period.  We will issue
additional  prospectus  supplements  that  reflect any future  issuances  of the
Product Escrow Shares.

     Prior  to the  acquisition  of Shaba by  Activision,  Shaba  was a party to
various  development  agreements with Activision.  Other than such contracts and
the fact that the Selling  Stockholders  were  members of Shaba,  which became a
wholly owned  subsidiary  of Activision on March 26, 2002 pursuant to the Merger
Agreement,  none of the Selling  Stockholders  listed  above have had a material
relationship with Activision within the past three years.
