The 7th installment of the crazy fun racing game Uphill Rush is now available. Speed your way through a waterpark with fun rollercoaster rides as you knock away bystanders. Uphill Rush 7: waterpark is definitely a fun ride and we love this game for being released appropriately around summertime for some indoor summer fun. Love it. This makes me want to head to a waterpark soon, except without the risk of flying off a slide! Yikes!
