I've been playing the new fear the walking dead and it reminds me of a game that is very similar . I believe it was a side scrolling runner . Running. And must jump over objects like cars and barriers . It could have been black and white starting out and in which u bought and upgraded weapons doing the same thing, shooting zombies . I'm pretty sure it's one huge map at which you start of running slow and then building speed the further u get hitting a checkpoint and it changes the background.
