As of today, EoN's alpha server is back in business, with the invite-only testing build boasting "noticeably quicker and more dynamic MOBA gameplay, streamlined UI, cleaner graphics, smaller teams, and more powerful heroes," Trion says.
Teams now feature two to four players, the objectives are more focused, and there's more of an emphasis on commander abilities plus four new classes. Finally, Trion has added something called "streamlined tactical leveling" that allows players to advance on the fly. You can register for an alpha or summer 2013 beta invitation via the official site link below.
