The beta is available to backers, so I took a look at it. The only class is the “operator”, which gets two edges. Edges are (more or less) class features from classes in SWN and WWN that you can mix and match. Magic is handled through an edge. You get an effort pool and four spells. Casting seems like a mix of psionics and mages from SWN and WWN respectively. You prepare spells, but casting them takes effort. If you run out of effort (or don’t want to commit any), you can overcast. In some ways it’s not as bad as torching (you can’t lose any attributes), but in some ways it’s worse (you’re likely to lose some of your next turn and may die).
