GameStop Corp. was hit with a second breach-of-contract suit Thursday in Delaware federal court, with a spatial planning and logistics software company claiming more than $600,000 in contracted services remained unpaid.

Georgia-based MerchLogix Inc. was represented by Polsinelli attorneys who declined to comment on the case Friday. They said in its complaint that the money is more than a month overdue based on the terms of the contract that the companies entered into in June.
