(“Zoo Entertainment”). The filing of any amendment to this Schedule 13D (including the filing of this Amendment No. 13) shall not be construed to be an admission by any person that a material change has occurred in the facts set forth in this Schedule 13D or that such amendment is required under Rule 13d-2 of the Securities Exchange Act of 1934, as amended.

Item 3 of this Schedule 13D is hereby amended to include the following information:

As previously disclosed in this Schedule 13D, on March 9, 2012, Zoo Entertainment, Zoo Games, Inc., a Delaware corporation, Zoo Publishing, Inc., a New Jersey corporation, and indiePub, Inc., a Delaware corporation, as borrowers (collectively, the “Borrowers”), entered into a Loan and Security Agreement (as amended on July 30, 2012 by the First Amendment thereto (the “First Amendment”), and as further amended, modified, supplemented or restated from time to time, the “Loan Agreement”) with MMB Holdings LLC, a Delaware limited liability company (“MMB”), as lender. Under the Loan Agreement, MMB may, at any time and from time to time, elect to convert all or any portion of the amounts owed under the Loan Agreement (including outstanding principal, accrued and unpaid interest, and unreimbursed costs owed by the Borrowers to MMB) into shares of Common Stock, subject to adjustment for stock dividends and other similar transactions.

On September 20, 2012, MMB made an additional loan under the Loan Agreement to the Borrowers in the principal amount of $68,000.

On September 24, 2012, MMB made an additional loan under the Loan Agreement to the Borrowers in the principal amount of $2,000.

On September 27, 2012, MMB made an additional loan under the Loan Agreement to the Borrowers in the principal amount of $185,000.

On September 28, 2012, MMB made an additional loan under the Loan Agreement to the Borrowers in the principal amount of $20,000.

On October 12, 2012, MMB made an additional loan under the Loan Agreement to the Borrowers in the principal amount of $141,235.

On October 16, 2012, MMB made an additional loan under the Loan Agreement to the Borrowers in the principal amount of $93,765.

On November 9, 2012, MMB and the Borrowers entered into a Second Amendment to the Loan Agreement (the “Second Amendment”) to permit the Borrowers to borrow up to an aggregate additional principal amount of $150,000 under the Loan Agreement. Concurrently with the execution and delivery of the Second Amendment, MMB made a loan under the Loan Agreement to the Borrowers in the principal amount of $98,687.

On November 13, 2012, MMB made an additional loan under the Loan Agreement to the Borrowers in the principal amount of $49,133.

On November 28, 2012, MMB and the Borrowers entered into a Third Amendment to the Loan Agreement (the “Third Amendment”) to permit the Borrowers to borrow up to an aggregate additional principal amount of $850,000 under the Loan Agreement. Concurrently with the execution and delivery of the Third Amendment, MMB made a loan under the Loan Agreement to the Borrowers in the principal amount of $252,180.

In connection with the Third Amendment, the Borrowers and MMB also: (i) cancelled the warrant issued by Zoo Entertainment to MMB on March 9, 2012, (ii) cancelled the warrant issued by Zoo Entertainment to MMB on July 30, 2012, and (iii) reduced the conversion price at which the amounts owed under the Loan Agreement may be converted into Common Stock (the “Conversion Price”) from $0.40 per share to $0.15 per share.

After giving effect to such loans and all prior loans and capitalization of interest, the current outstanding principal balance under the Loan Agreement is approximately $6,495,590. If the entirety of such outstanding principal balance were converted into shares of Common Stock pursuant to the Loan Agreement at the Conversion Price, MMB would receive, in the aggregate, 43,303,931 shares of Common Stock, subject to adjustment for stock dividends and other similar transactions. The actual number of shares (if any) that MMB may receive in connection with any exercise of its conversion rights under the Loan Agreement may be higher or lower depending upon, among other factors, (x) whether MMB elects to convert less than the full amount that MMB is entitled to convert under the Loan Agreement, and (y) whether any additional accrued or unpaid interest or unreimbursed costs owed by the Borrowers to MMB is capitalized from time to time into the loan balance instead of paid to MMB in cash.

The foregoing description of the Loan Agreement (including the First Amendment, the Second Amendment and the Third Amendment) is a summary only and is qualified in its entirety by reference to the full text thereof, which are filed, respectively as exhibits to this Schedule 13D and are hereby incorporated herein by reference.

Item 4 of this Schedule 13D is hereby amended to add the following information:

The information set forth in Item 3 above is incorporated by reference into this Item 4.

The purpose of the Second Amendment and the Third Amendment is to assist the Borrowers with their liquidity needs, including by providing working capital to the Borrowers.

MMB may at any time and from time to time, for any reason or no reason at all, exercise its rights under the Loan Agreement to convert all or any portion of the amounts owed under the Loan Agreement (including outstanding principal, accrued and unpaid interest, and unreimbursed costs owed by the Borrower to MMB) into shares of Common Stock pursuant to the Loan Agreement. Factors that MMB might consider when determining whether to exercise any such rights include the financial condition of the Borrowers, the future prospects of the Borrowers, the availability of additional financing by the Borrowers from other sources, the possibility of an extraordinary transaction involving any of the Borrowers, and any need or desire on the part of MMB to redeem, in whole or in part, the interests in MMB of one or more owners of MMB.
