Blitz Game Studios owned site IndieCity.com is halfway to its latest Developer Challenge target, asking developers to submit 100 games to the site's store.
If the target is reached by December 31 then the revenue structure offered to developers submitting titles will change, rising to 90 per cent for games with integrated achievements, or 80 per cent without.
"Once this tier of Challenge is complete, the next level will open up allowing developers to earn 95 per cent of their games' revenue from 250 games on the Store."
If the service hits 500 games developers will receive 100 per cent of revenue.
The site was announced November 2010, and aims to be an online destination for all indie games.
"We want to bring together developers, gamers and press to make IndieCity the one stop shop to find, download, talk about and buy these games that are being made by so many talented people."
