If I was to stream this game through the PS4 streaming system and have that timer in the corner would that be enough or no? I know for some games it is allowed but just wanted to check if it was allowed for Dead Island Riptide? Me and my girlfriend would love to Speedrun the game :)

The rules specify "The timer does not have to be shown on the video, but the time must be verifiable."

So yeah, you should be good, have fun! :)
