As of today, another game has been added to the eighth iteration of the Humble Indie Bundle. Oil Rush, a naval strategy game developed by UNIGINE Corp. has been added to the premium version of the bundle, which is received when donors offer more than the average contribution for the bundle. The game promises real time naval warfare across multiple locations, a rich technology tree, and easy-to-learn, difficult-to-master gameplay.

Oil Rush joins the likes of Hotline Miami, Proteus, Tiny and Big in Grandpa’s Leftovers, Intrusion 2 and English Country Tune in the bundle when a donation of more than $5.69 is given. Even if less than the $5.69 price point is donated though, the bundle still includes Little Inferno, Awesomenauts, Thomas Was Alone, and Dear Esther. Bought separately, the bundle would come to more than $150. All money given to the bundle supports indie developers like UNIGINE Corp. and charity funds.
