The relaunched Mythos MMO has released a trailer explaining the classes. You have a Pyromancer, a Bloodletter, and the one Alec will choose, Gadgeteer. See them fight! See them also fight! See them fight! It's hack-n-slash MMOing, which is something every sane mind wants. As is traditional in our custom, you can watch the video below.
The game's due next year, although specifics aren't available. However, you can currently sign up for the forthcoming beta.
