5th Planet is the first third-party developer to publish a game with Kabam, having just launched Clash of the Dragons on the company’s web portal.

Clash of the Dragons launched on Kongregate in December 2011, with the developer reporting 300,000 installs within 30 days. This is the second CCG 5th Planet’s put out within the past month, having launched Legacy of Heroes on Kongregate’s portal on July 9. 5th Planet Games is finding great success as it expands from Facebook to other platforms and game networks; this year the developer is on track to bring in $10 million in annual revenue.

We spoke to Kabam VP, Corporate Communications Steve Swasey this morning at Casual Connect before spotting the game on Kabam’s portal. When asked about publishing third-party titles, Swasey said the company had no official comment yet, but to stay tuned for related news.
