In this episode I talk to NoReason, who you will probably know for his  challenging slaughter maps, starting with his early releases Disparate  Realities and Death in Excess as well as his 3 NoSp speedmapping  projects and the gargantuan Cosmogenesis.  

We talk about the benefits and pitfalls of speedmapping, the making of a  giant slaughter map, and the benefits of MBF21.
