It's been confirmed that entering an EMMI zone is a checkpoint, meaning if you die to an EMMI you don't have to reload the save and maybe grab a power up you found on the way after every death
Ehhhh. I love the SAX conceptually. In practise, it's stupid as **** and only appears in scripted sequences whereas EMMI will hunt you down with terrifying levels of competence, where the SAX would run in circles, EMMI just finds new entrances to get to you. It's easy to see why Sakamoto cited technical limitations for Dread'z development back then
