Finnish indie developer Housemarque have confirmed on twitter that they will be showing off one of their two PS4 titles in development at Gamescom in Cologne in two weeks time. One of the two titles is said to be a spiritual successor to Super Stardust HD. It remains to be seen if the title is an exclusive or not and whether this is the game shown or whether we'll get to see the second title that is still shrouded in mystery.
